Kazakh language
–
Kazakh belongs to the Kipchak branch of the Turkic languages. It is closely related to Nogai, Kyrgyz, and especially Karakalpak, Kazakh is also spoken by many ethnic Kazakhs through the former Soviet Union, Afghanistan, Iran, Turkey, and Germany. Like other Turkic languages, Kazakh is a language. The Kazakh language has its speakers spread over a vast territory from the Tian Shan to the shore of Caspian Sea. Kazakh is the state language of Kazakhstan, in which nearly 10 million speakers are reported to live. In China, more than one million ethnic Kazakhs and Kazakh speakers reside in Ili Kazakh Autonomous Prefecture in Xinjiang. Today, Kazakh is written in Cyrillic in Kazakhstan and Mongolia, the oldest known written records of languages closely related to Kazakh were written in the Old Turkic alphabet. However, it is not believed any of these varieties were direct predecessors of Kazakh. Modern Kazakh has historically been written using versions of the Latin, in October 2006, Nursultan Nazarbayev, the President of Kazakhstan, brought up the topic of using the Latin alphabet instead of the Cyrillic alphabet as the official script for Kazakh in Kazakhstan. A Kazakh government study released in September 2007 said that Kazakhstan could feasibly switch to a Latin script over a 10- to 12-year period, the transition was halted temporarily on December 13,2007, with President Nazarbayev declaring, “For 70 years the Kazakhstanis read and wrote in Cyrillic. More than 100 nationalities live in our state, thus we need stability and peace. We should be in no hurry in the issue of alphabet transformation”, Kazakh exhibits tongue-root vowel harmony, with some words of recent foreign origin as exceptions. There is also a system of rounding harmony which resembles that of Kyrgyz, the following chart depicts the consonant inventory of standard Kazakh, many of the sounds, however, are allophones of other sounds or appear only in recent loan-words. The 18 consonant phonemes listed by Vajda are in bold—since these are phonemes, their place and manner of articulation are very general. The borrowed phonemes /f/, /v/, /ɕ/, /t͡ɕ/ and /x/, only occur in recent mostly Russian borrowings, in the table, the elements left of a divide are voiceless, while those to the right are voiced. Kazakh has a system of nine phonemic vowels, three of which are diphthongs, the rounding contrast and /æ/ generally only occur as phonemes in the first syllable of a word, but do occur later allophonically, see the section on harmony below for more information. According to Vajda, the quality of vowels is actually one of neutral versus retracted tongue root. Per convention, rounded vowels are presented to the right of their unrounded counterparts, phonetic values are paired with the corresponding character in Kazakhs Cyrillic alphabet

Uzbek language
–
Uzbek is a Turkic language and the official language of Uzbekistan. It has 27 million native speakers and is spoken by the Uzbeks in Uzbekistan, Uzbek belongs to the Eastern Turkic, or Karluk, branch of the Turkic language family. External influences include Persian, Arabic and Russian, one of the most noticeable distinctions of Uzbek from other Turkic languages is the rounding of the vowel /a/ to /ɒ/ or /ɔ/, a feature that was influenced by Persian. In the language itself, Uzbek is oʻzbek tili or oʻzbekcha, in Cyrillic, the same names are written ўзбек тили and ўзбекча, in Arabic script, ازبېک تیلی and ازبېجه. The first Turkic dynasty in the region was that of the Kara-Khanid Khanate in the 9th–12th centuries, the language was championed by Ali-Shir Navai in the 15th and 16th centuries. Navai was the greatest representative of Chagatai language literature and he significantly contributed to the development of the Chagatay language and its direct descendant Uzbek and is widely considered to be the founder of Uzbek literature. Ultimately based on the Karluk variant of the Turkic languages, Chagatay contained large numbers of Persian, by the 19th century it was rarely used for literary composition, but disappeared only in the early 20th century. The term Uzbek as applied to language has meant different things at different times, all three dialects continue to exist within modern spoken Uzbek. Edward A. Allworth argued that this badly distorted the history of the region and was used to give authors such as the 15th century author Ali-Shir Navai an Uzbek identity. Estimates of the number of speakers of Uzbek vary widely, the Swedish encyclopedia Nationalencyklopedin estimates the number of native speakers to be 26 million, and the CIA World Factbook estimates 25 million. The influence of Islam, and by extension, Arabic, is evident in Uzbek loanwords, there is also a residual influence of Russian, from the time when Uzbeks were under the rule of the Russian Empire and the Soviet Union. Uzbek vocabulary has also heavily influenced by Persian through its historic roots. The Uzbek language has many dialects, varying widely from region to region, however, there is a commonly understood dialect which is used in mass media and in most printed materials. Among the most-widespread dialects are the Tashkent dialect, Afghan dialect, the Ferghana dialect, the Khorezm dialect, the Chimkent-Turkestan dialect, 1928–1940, the Latin-based Yañalif used officially. 1940–1992, the Cyrillic script used officially, since 1992, Yañalif is official in Uzbekistan, although the Cyrillic script is still widely used. Despite the official status of the Latin script in Uzbekistan, the use of Cyrillic is still widespread, especially in advertisements, in newspapers, scripts may be mixed, with headlines in Latin and articles in Cyrillic. The Arabic script is no longer used in Uzbekistan except symbolically in limited texts or for the studies of Chagatai. In the western Chinese region of Xinjiang, where there is an Uzbek minority, however, the Uyghur Arabic alphabet is sometimes used

Russian language
–
Russian is an East Slavic language and an official language in Russia, Belarus, Kazakhstan, Kyrgyzstan and many minor or unrecognised territories. Russian belongs to the family of Indo-European languages and is one of the four living members of the East Slavic languages, written examples of Old East Slavonic are attested from the 10th century and beyond. It is the most geographically widespread language of Eurasia and the most widely spoken of the Slavic languages and it is also the largest native language in Europe, with 144 million native speakers in Russia, Ukraine and Belarus. Russian is the eighth most spoken language in the world by number of native speakers, the language is one of the six official languages of the United Nations. Russian is also the second most widespread language on the Internet after English, Russian distinguishes between consonant phonemes with palatal secondary articulation and those without, the so-called soft and hard sounds. This distinction is found between pairs of almost all consonants and is one of the most distinguishing features of the language, another important aspect is the reduction of unstressed vowels. Russian is a Slavic language of the Indo-European family and it is a lineal descendant of the language used in Kievan Rus. From the point of view of the language, its closest relatives are Ukrainian, Belarusian, and Rusyn. An East Slavic Old Novgorod dialect, although vanished during the 15th or 16th century, is considered to have played a significant role in the formation of modern Russian. In the 19th century, the language was often called Great Russian to distinguish it from Belarusian, then called White Russian and Ukrainian, however, the East Slavic forms have tended to be used exclusively in the various dialects that are experiencing a rapid decline. In some cases, both the East Slavic and the Church Slavonic forms are in use, with different meanings. For details, see Russian phonology and History of the Russian language and it is also regarded by the United States Intelligence Community as a hard target language, due to both its difficulty to master for English speakers and its critical role in American world policy. The standard form of Russian is generally regarded as the modern Russian literary language, mikhail Lomonosov first compiled a normalizing grammar book in 1755, in 1783 the Russian Academys first explanatory Russian dictionary appeared. By the mid-20th century, such dialects were forced out with the introduction of the education system that was established by the Soviet government. Despite the formalization of Standard Russian, some nonstandard dialectal features are observed in colloquial speech. Thus, the Russian language is the 6th largest in the world by number of speakers, after English, Mandarin, Hindi/Urdu, Spanish, Russian is one of the six official languages of the United Nations. Education in Russian is still a choice for both Russian as a second language and native speakers in Russia as well as many of the former Soviet republics. Russian is still seen as an important language for children to learn in most of the former Soviet republics, samuel P. Huntington wrote in the Clash of Civilizations, During the heyday of the Soviet Union, Russian was the lingua franca from Prague to Hanoi

Kazakhstan
–
Kazakhstan, officially the Republic of Kazakhstan, is a transcontinental country in northern Central Asia and Eastern Europe. Kazakhstan is the worlds largest landlocked country, and the ninth largest in the world, Kazakhstan is the dominant nation of Central Asia economically, generating 60% of the regions GDP, primarily through its oil/gas industry. It also has vast mineral resources, Kazakhstan is officially a democratic, secular, unitary, constitutional republic with a diverse cultural heritage. Kazakhstan shares borders with Russia, China, Kyrgyzstan, Uzbekistan, and Turkmenistan, the terrain of Kazakhstan includes flatlands, steppe, taiga, rock canyons, hills, deltas, snow-capped mountains, and deserts. Kazakhstan has an estimated 18 million people as of 2014, Given its large area, its population density is among the lowest. The capital is Astana, where it was moved in 1997 from Almaty, the territory of Kazakhstan has historically been inhabited by nomadic tribes. This changed in the 13th century, when Genghis Khan occupied the country as part of the Mongolian Empire, following internal struggles among the conquerors, power eventually reverted to the nomads. By the 16th century, the Kazakh emerged as a distinct group, the Russians began advancing into the Kazakh steppe in the 18th century, and by the mid-19th century, they nominally ruled all of Kazakhstan as part of the Russian Empire. Following the 1917 Russian Revolution, and subsequent civil war, the territory of Kazakhstan was reorganised several times, in 1936, it was made the Kazakh Soviet Socialist Republic, part of the Soviet Union. Kazakhstan was the last of the Soviet republics to declare independence during the dissolution of the Soviet Union in 1991, Kazakhstan has worked to develop its economy, especially its dominant hydrocarbon industry. Kazakhstans 131 ethnicities include Kazakhs, Russians, Uzbeks, Ukrainians, Germans, Tatars, the Kazakh language is the state language, and Russian has equal official status for all levels of administrative and institutional purposes. The name Kazakh comes from the ancient Turkic word qaz, to wander, the name Cossack is of the same origin. The Persian suffix -stan means land or place of, so Kazakhstan can be translated as land of the wanderers. Kazakhstan has been inhabited since the Neolithic Age, the regions climate, archaeologists believe that humans first domesticated the horse in the regions vast steppes. Central Asia was originally inhabited by the Scythians, the Cuman entered the steppes of modern-day Kazakhstan around the early 11th century, where they later joined with the Kipchak and established the vast Cuman-Kipchak confederation. Under the Mongol Empire, the largest in history, administrative districts were established. These eventually came under the rule of the emergent Kazakh Khanate, throughout this period, traditional nomadic life and a livestock-based economy continued to dominate the steppe. Nevertheless, the region was the focus of ever-increasing disputes between the native Kazakh emirs and the neighbouring Persian-speaking peoples to the south, at its height the Khanate would rule parts of Central Asia and control Cumania

Uzbekistan
–
Uzbekistan, officially the Republic of Uzbekistan, is one of only two doubly landlocked countries in the world. Located in Central Asia, it is a unitary, constitutional, presidential republic, comprising twelve provinces, one autonomous republic and a capital city. Uzbekistan is bordered by five landlocked countries, Kazakhstan to the north, Tajikistan to the southeast, Kyrgyzstan to the northeast, Afghanistan to the south, and Turkmenistan to the southwest. Once part of the Turkic Khaganate and later Timurid Empires, the region that includes the Republic of Uzbekistan was conquered in the early 16th century by Eastern Turkic-speaking nomads. Following the breakup of the Soviet Union, it declared independence as the Republic of Uzbekistan on 31 August 1991, Uzbekistan is officially a democratic, secular, unitary, constitutional republic with a diverse cultural heritage. The countrys official language is Uzbek, a Turkic language written in the Latin alphabet and spoken natively by approximately 85% of the population, however, Uzbeks constitute 81% of the population, followed by Russians, Tajiks, Kazakhs, and others. A majority of Uzbeks are non-denominational Muslims, Uzbekistan is a member of the Commonwealth of Independent States, Organization for Security and Co-operation in Europe, UN, and the SCO. While officially a republic, non-governmental human rights organizations define Uzbekistan as an authoritarian state with limited civil rights. Uzbekistans economy relies mainly on commodity production, including cotton, gold, uranium, despite the declared objective of transition to a market economy, its government continues to maintain economic controls which imports in favour of domestic import substitution. Uzbekistan has an area of 447,400 square kilometres and it is the 56th largest country in the world by area and the 42nd by population. Among the CIS countries, it is the 4th largest by area, Uzbekistan lies between latitudes 37° and 46° N, and longitudes 56° and 74° E. It stretches 1,425 kilometres from west to east and 930 kilometres from north to south, Uzbekistan also shares a short border with Afghanistan to the south. Uzbekistan is a dry, landlocked country and it is one of two doubly landlocked countries in the world, the other being Liechtenstein. In addition, due to its location within a series of endorheic basins, less than 10% of its territory is intensively cultivated irrigated land in river valleys and oases. The rest is vast desert and mountains, the climate in the Republic of Uzbekistan is continental, with little precipitation expected annually. The average summer high temperature tends to be 40 °C, while the winter low temperature is around −23 °C. Uzbekistan has a rich and diverse natural environment, the Aral Sea used to be the fourth-largest inland sea on Earth, acting as an influencing factor in the air moisture and arid land use. Since the 1960s, the decade when the misuse of the Aral Sea water began, it has shrunk to less than 50% of its former area, reliable, or even approximate data, have not been collected, stored or provided by any organization or official agency

Central Asia
–
Central Asia stretches from the Caspian Sea in the west to China in the east and from Afghanistan in the south to Russia in the north. It is also referred to as the -stans as the five countries generally considered to be within the region all have names ending with the Persian suffix -stan. Central Asias five former Soviet republics are Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, Central Asia has historically been closely tied to its nomadic peoples and the Silk Road. It has acted as a crossroads for the movement of people, goods, the Silk Road connected Muslim lands with the people of Europe, India, and China. This crossroads position has intensified the conflict between tribalism and traditionalism and modernization, in pre-Islamic and early Islamic times, Central Asia was predominantly Iranian, peopled by Eastern Iranian-speaking Bactrians, Sogdians and Chorasmians and the semi-nomadic Scythians and Parthians. Central Asia is sometimes referred to as Turkestan, the idea of Central Asia as a distinct region of the world was introduced in 1843 by the geographer Alexander von Humboldt. The borders of Central Asia are subject to multiple definitions, historically built political geography and geoculture are two significant parameters widely used in the scholarly literature about the definitions of the Central Asia. The most limited definition was the one of the Soviet Union. This definition was also used outside the USSR during this period. However, the Russian culture has two terms, Средняя Азия and Центральная Азия. Since then, this has become the most common definition of Central Asia, the UNESCO general history of Central Asia, written just before the collapse of the USSR, defines the region based on climate and uses far larger borders. An alternative method is to define the region based on ethnicity and these areas include Xinjiang Uyghur Autonomous Region, the Turkic regions of southern Siberia, the five republics, and Afghan Turkestan. Afghanistan as a whole, the northern and western areas of Pakistan, the Tibetans and Ladakhi are also included. Insofar, most of the peoples are considered the indigenous peoples of the vast region. Central Asia is a large region of varied geography, including high passes and mountains, vast deserts. The vast steppe areas of Central Asia are considered together with the steppes of Eastern Europe as a geographical zone known as the Eurasian Steppe. Much of the land of Central Asia is too dry or too rugged for farming, the Gobi desert extends from the foot of the Pamirs, 77° E, to the Great Khingan Mountains, 116°–118° E. Central Asia has the following geographic extremes, The worlds northernmost desert, at Buurug Deliin Els, Mongolia, the Northern Hemispheres southernmost permafrost, at Erdenetsogt sum, Mongolia, 46°17′ N

Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Body of water
–
A body of water or waterbody is any significant accumulation of water, generally on a planets surface. The term most often refers to oceans, seas, and lakes, a body of water does not have to be still or contained, Rivers, streams, canals, and other geographical features where water moves from one place to another are also considered bodies of water. Most are naturally occurring geographical features, but some are artificial, there are types that can be either. For example, most reservoirs are created by engineering dams, similarly, most harbors are naturally occurring bays, but some harbors have been created through construction. Bodies of water that are navigable are known as waterways, some bodies of water collect and move water, such as rivers and streams, and others primarily hold water, such as lakes and oceans. The term body of water can also refer to a reservoir of water held by a plant, note that there are some geographical features involving water that are not bodies of water, for example waterfalls, geysers and rapids. Arm of the sea - also sea arm, used to describe a sea loch, arroyo - a usually dry creek bed or gulch that temporarily fills with water after a heavy rain, or seasonally. Artificial lake or artificial pond - see reservoir or impoundment, barachois - a lagoon separated from the ocean by a sand bar. Bay - an area of water bordered by land on three sides, similar to, but smaller than a gulf, bayou - a slow-moving stream or a marshy lake. Bight - a large and often only slightly receding bay, or a bend in any geographical feature, billabong - see Oxbow lake, a pond or still body of water created when a river changes course and some water becomes trapped. Boil - see Seep Brook - a small stream, canal - an artificial waterway, usually connected to existing lakes, rivers, or oceans. Channel - the physical confine of a river, slough or ocean consisting of a bed. See also stream bed and strait, earth scientists generally use the term to describe a circular or round inlet with a narrow entrance, though colloquially the term is sometimes used to describe any sheltered bay. Basin - a region of land where water from rain or snowmelt drains downhill into another body of water, such as a river, lake, creek - an inlet of the sea, narrower than a cove. Delta - the location where a river flows into an ocean, sea, estuary, lake, distributary or distributary channel - a stream that branches off and flows away from a main stream channel. Draw - a usually dry creek bed or gulch that temporarily fills with water after a heavy rain, fjord - a submergent landform which has occurred due to glacial activity. Glacier - a large collection of ice or a river that moves slowly down a mountain. Glacial Pothole - see Kettle Gulf - a part of a lake or ocean that extends so that it is surrounded by land on three sides, similar to, but larger than a bay, headland - an area of water bordered by land on three sides

Endorheic basin
–
Such a basin may also be referred to as a closed or terminal basin or as an internal drainage system. However, in a basin, rain that falls within it does not flow out but may only leave the drainage system by evaporation. The bottom of such a basin is occupied by a salt lake or salt pan. Endorheic regions, in contrast to regions which flow to the ocean in geologically defined patterns, are closed hydrologic systems. Their surface waters drain to inland terminal locations where the water evaporates or seeps into the ground, endorheic water bodies include some of the largest lakes in the world, such as the Aral Sea and the Caspian Sea, the worlds largest saline inland sea. Most endorheic basins are arid, although there are notable exceptions, such as the Valley of Mexico, the Lake Tahoe region. Endorheic basins can be massively and rapidly affected by change and excessive water removal. An exorheic lake naturally remains at a level, so water flow into the lake may be many times more than is needed to maintain its present size. In contrast, an endorheic basin does not have enough inflow that it overflows to the ocean, endorheic lakes are bodies of water that do not flow into the sea. Most of the water falling on Earth finds its way to the oceans through a network of rivers, lakes, however, there is a class of water bodies that are located in closed or endorheic watersheds where the topography prevents their drainage to the oceans. These endorheic watersheds are often called terminal lakes or sink lakes, endorheic lakes are usually in the interior of a landmass, far from an ocean in areas of relatively low rainfall. Their watersheds are often confined by natural geologic land formations such as a mountain range, the inland water flows into dry watersheds where the water evaporates, leaving a high concentration of minerals and other inflow erosion products. Over time this input of erosion products can cause the lake to become relatively saline. Endorheic regions can occur in any climate but are most commonly found in desert locations, the Black Sea was likely such a lake, having once been an independent hydrological system before the Mediterranean Sea broke through the terrain separating the two. Lake Bonneville was another such lake, overflowing its basin in the Bonneville flood, malheur/Harney Lake in Oregon is normally cut off from drainage to the ocean, but has an outflow channel to the Malheur River that is normally dry, but flows in years of peak precipitation. Examples of relatively humid regions in endorheic basins often exist at high elevation and these regions tend to be marshy and are subject to substantial flooding in wet years. The area containing Mexico City is one case, with annual precipitation of 850 mm. Endorheic regions tend to be far inland with their boundaries defined by mountains or other features that block their access to oceans

Lake
–
A lake is an area of variable size filled with water, localized in a basin, that is surrounded by land, apart from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, and therefore are distinct from lagoons, Lakes can be contrasted with rivers or streams, which are usually flowing. Most lakes are fed and drained by rivers and streams, natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, in some parts of the world there are many lakes because of chaotic drainage patterns left over from the last Ice Age. All lakes are temporary over geologic time scales, as they will fill in with sediments or spill out of the basin containing them. The word lake comes from Middle English lake, from Old English lacu, from Proto-Germanic *lakō, cognates include Dutch laak, Middle Low German lāke as in, de, Moorlake, de, Wolfslake, de, Butterlake, German Lache, and Icelandic lækur. Also related are the English words leak and leach, none of these definitions completely excludes ponds and all are difficult to measure. For this reason, simple size-based definitions are used to separate ponds. One definition of lake is a body of water of 2 hectares or more in area, however, others have defined lakes as waterbodies of 5 hectares and above, or 8 hectares and above. Charles Elton, one of the founders of ecology, regarded lakes as waterbodies of 40 hectares or more. The term lake is used to describe a feature such as Lake Eyre. In common usage, many bear names ending with the word pond. One textbook illustrates this point with the following, In Newfoundland, for example, almost every lake is called a pond, whereas in Wisconsin, the majority of lakes on Earth are fresh water, and most lie in the Northern Hemisphere at higher latitudes. Canada, with a drainage system has an estimated 31,752 lakes larger than 3 square kilometres and an unknown total number of lakes. Finland has 187,888 lakes 500 square metres or larger, most lakes have at least one natural outflow in the form of a river or stream, which maintain a lakes average level by allowing the drainage of excess water. Some lakes do not have an outflow and lose water solely by evaporation or underground seepage or both. Many lakes are artificial and are constructed for power generation, aesthetic purposes, recreational purposes, industrial use. Globally, lakes are greatly outnumbered by ponds, of an estimated 304 million standing water bodies worldwide, 91% are 1 hectare or less in area
11.
Reservoir
–
A reservoir is a storage space for fluids. These fluids may be water, hydrocarbons or gas, a reservoir usually means an enlarged natural or artificial lake, storage pond or impoundment created using a dam or lock to store water. Reservoirs can be created by controlling a stream that drains a body of water. They can also be constructed in river valleys using a dam, alternately, a reservoir can be built by excavating flat ground or constructing retaining walls and levees. Tank reservoirs store liquids or gases in storage tanks that may be elevated, at grade level, tank reservoirs for water are also called cisterns. Underground reservoirs are used to store liquids, principally either water or petroleum, a dam constructed in a valley relies on the natural topography to provide most of the basin of the reservoir. Dams are typically located at a part of a valley downstream of a natural basin. The valley sides act as walls, with the dam located at the narrowest practical point to provide strength. In many reservoir construction projects, people have to be moved and re-housed, construction of a reservoir in a valley will usually need the river to be diverted during part of the build, often through a temporary tunnel or by-pass channel. In hilly regions, reservoirs are constructed by enlarging existing lakes. Sometimes in such reservoirs the new top water level exceeds the height on one or more of the feeder streams such as at Llyn Clywedog in Mid Wales. In such cases additional side dams are required to contain the reservoir, where water is pumped or siphoned from a river of variable quality or quantity, bank-side reservoirs may be built to store the water. Such reservoirs are usually formed partly by excavation and partly by building a complete encircling bund or embankment, the water stored in such reservoirs may stay there for several months, during which time normal biological processes may substantially reduce many contaminants and almost eliminate any turbidity. The use of reservoirs also allows water abstraction to be stopped for some time. Service reservoirs store fully treated potable water close to the point of distribution, many service reservoirs are constructed as water towers, often as elevated structures on concrete pillars where the landscape is relatively flat. Other service reservoirs can be almost entirely underground, especially in hilly or mountainous country. In the United Kingdom, Thames Water has many underground reservoirs, sometimes called cisterns, built in the 1800s. A good example is the Honor Oak Reservoir in London, constructed between 1901 and 1909, when it was completed it was said to be the largest brick built underground reservoir in the world and it is still one of the largest in Europe

Inflow (hydrology)
–
In hydrology, the inflow of a body of water is the source of the water in the body of water. It can also refer to the volume of incoming water in unit time. All bodies of water have multiple inflows, but often, one inflow may predominate, however, in many cases, no single inflow will predominate and there will be multiple primary inflows. For a lake, the inflow may be a river or stream that flows into the lake. Inflow may also be, strictly speaking, not flows, but rather precipitation, inflow can also be used to refer to groundwater recharge. The dictionary definition of inflow at Wiktionary

Syr Darya
–
The Syr Darya /ˌsɪərˈdɑːrjə/ is a river in Central Asia. It is the northern and eastern of the two rivers in the endorrheic basin of the Aral Sea, the other being the Amu Darya. The second part of the name river in Persian. The current name only from the 18th century. The earliest recorded name comes down to us as Jaxartes /ˌdʒæɡˈzɑːrtiːz/ or Iaxartes /ˌaɪ. əɡˈzɑːrtiːz/ in Ancient Greek and this name is recorded by several sources, including those relating to Alexander the Great kage the great. The Greek preserves the Old Persian name Yakhsha Arta, perhaps a reference to the color of its glacially-fed water, more evidence for the Persian etymology comes from its Turkic name up to the time of the Arab conquest, the Yinchu, or Pearl river. Following the Muslim conquest, the river appears in the sources uniformly as the Seyhun, the current local name of the river, Syr, does not appear before the 16th century. In the 17th century, Abu al-Ghazi Bahadur Khan, historian and ruler of Khiva, calls the Aral Sea the Sea of Sïr and its annual flow is a very modest 37 cubic kilometres per year—half that of its sister river, the Amu Darya. Along its course, the Syr Darya irrigates the most productive cotton-growing region in the whole of Central Asia, together with the towns of Kokand, Khujand, Kyzylorda, various local governments throughout history have built and maintained an extensive system of canals. These canals are of importance in this arid region. Many fell into disuse in the 17th and early 18th century, massive expansion of irrigation canals in Middle and Lower Syr Darya during the Soviet period to water cotton and rice fields caused ecological damage to the area. The amount of water taken from the river was such that in some periods of the year, no water at all reaches the Aral Sea, similar to the Amu Darya situation in Uzbekistan and Turkmenistan. During the era of Alexander the Great, the Syr Darya marked the northernmost limit of Hellenic conquests and also the site of a famous battle, the Battle of Jaxartes. It was on the shores of the Syr Darya that Alexander placed a garrison in the City of Cyrus, for most of its history since at least the Muslim Conquest of Central Asia, the name of this city has been Khujand. In return, Kyrgyzstan and Tajikistan received Kazakh, Turkmen, and Uzbek coal, gas, after the fall of the Soviet Union this system disintegrated and the Central Asian nations have failed to reinstate it. Inadequate infrastructure, poor management, and outdated irrigation methods all exacerbate the issue. Britannica. com Livius. org, Jaxartes BBC News, Syn Darya in pictures

Groundwater
–
Groundwater is the water present beneath Earths surface in soil pore spaces and in the fractures of rock formations. A unit of rock or a deposit is called an aquifer when it can yield a usable quantity of water. The depth at which pore spaces or fractures and voids in rock become completely saturated with water is called the water table. Groundwater is recharged from, and eventually flows to, the naturally, natural discharge often occurs at springs and seeps. Groundwater is also withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction wells. The study of the distribution and movement of groundwater is hydrogeology, Groundwater is hypothesized to provide lubrication that can possibly influence the movement of faults. It is likely that much of Earths subsurface contains some water, Groundwater may not be confined only to Earth. The formation of some of the landforms observed on Mars may have influenced by groundwater. There is also evidence that water may also exist in the subsurface of Jupiters moon Europa. Groundwater is often cheaper, more convenient and less vulnerable to pollution than surface water, therefore, it is commonly used for public water supplies. For example, groundwater provides the largest source of water storage in the United States. Underground reservoirs contain far more water than the capacity of all surface reservoirs and lakes in the US, many municipal water supplies are derived solely from groundwater. Polluted groundwater is less visible, but more difficult to clean up, than pollution in rivers, Groundwater pollution most often results from improper disposal of wastes on land. An aquifer is a layer of substrate that contains and transmits groundwater. When water can flow directly between the surface and the zone of an aquifer, the aquifer is unconfined. The deeper parts of unconfined aquifers are more saturated since gravity causes water to flow downward. The upper level of this layer of an unconfined aquifer is called the water table or phreatic surface. Below the water table, where in general all pore spaces are saturated with water, is the phreatic zone, substrate with low porosity that permits limited transmission of groundwater is known as an aquitard

Amu Darya
–
The Amu Darya, also called the Amu River and historically known by its Latin name, Oxus, is a major river in Central Asia. It is formed by the junction of the Vakhsh and Panj rivers, at Qaleh-ye Panjeh in Afghanistan, in ancient times, the river was regarded as the boundary between Greater Iran and Turan. In classical antiquity, the river was known as the Ōxus in Latin and Ὦξος Ôxos in Greek—a clear derivative of Vakhsh, in Vedic Sanskrit, the river is also referred to as Vakṣu. The Avestan texts too refer to the River as Yakhsha/Vakhsha, in Middle Persian sources of the Sassanid period the river is known as Wehrōd. The name Amu is said to have come from the city of Āmul, in modern Turkmenistan. Medieval Arabic and Muslim sources call the river Jayhoun which is derived from Gihon, however, this name is no longer used. Hara and to the river of Gozan (that is to say, the Amu. the Gozan River is the River Balkh, i. e. the Oxus or the Amu Darya. and were brought into Halah, and Habor, and Hara, and to the river Gozan. The rivers total length is 2,400 kilometres and its drainage basin totals 534,739 square kilometres in area, the river is navigable for over 1,450 kilometres. All of the water comes from the mountains in the south where annual precipitation can be over 1,000 mm. An ice cave at the end of the Wakhjir valley, in the Wakhan Corridor, in the Pamir Mountains, a glacier turns into the Wakhan River and joins the Pamir River about 50 kilometres downstream. Therefore, the Chelab stream may be considered the true source or parent stream of the Oxus. The Panj River forms the border of Afghanistan and Tajikistan and it flows west to Ishkashim where it turns north and then north-west through the Pamirs passing the Tajikistan–Afghanistan Friendship Bridge. It subsequently forms the border of Afghanistan and Uzbekistan for about 200 kilometres, passing Termez and it delineates the border of Afghanistan and Turkmenistan for another 100 kilometres before it flows into Turkmenistan at Atamurat. As the Amudarya, it flows across Turkmenistan south to north, passing Türkmenabat, use of water from the Amu Darya for irrigation has been a major contributing factor to the shrinking of the Aral Sea since the late 1950s. Historical records state that in different periods, the river flowed into the Aral Sea, into the Caspian Sea, about 1,385,045 square kilometres of land is drained by the Amu Darya into the Aral Sea endorheic basin. This includes most of Tajikistan, the southwest corner of Kyrgyzstan, the northeast corner of Afghanistan, part of the Amu Daryas drainage divide in Tajikistan forms that countrys border with China and Pakistan. About 61% of the lies within Tajikistan, Uzbekistan and Turkmenistan. Of the area drained by the Amu Darya, only about 200,000 square kilometres actively contribute water to the river and this is because many of the rivers major tributaries have been diverted, and much of the rivers drainage is dominated by outlying desert and steppe

Drainage basin
–
A drainage basin or catchment area is any area of land where precipitation collects and drains off into a common outlet, such as into a river, bay, or other body of water. Drainage basins connect into other drainage basins at elevations in a hierarchical pattern, with smaller sub-drainage basins. Other terms used to describe drainage basins are catchment, catchment basin, drainage area, river basin and water basin. In closed drainage basins the water converges to a point inside the basin, known as a sink, which may be a permanent lake. The drainage basin acts as a funnel by collecting all the water within the covered by the basin. Each drainage basin is separated topographically from adjacent basins by a perimeter, drainage basins are similar but not identical to hydrologic units, which are drainage areas delineated so as to nest into a multi-level hierarchical drainage system. Hydrologic units are defined to allow multiple inlets, outlets, or sinks, in a strict sense, all drainage basins are hydrologic units but not all hydrologic units are drainage basins. Drainage basins of the oceans and seas of the world. Grey areas are endorheic basins that do not drain to the oceans, the following is a list of the major ocean basins, About 48. 7% of the worlds land drains to the Atlantic Ocean. The two major mediterranean seas of the world also flow to the Atlantic, The Caribbean Sea and Gulf of Mexico basin includes most of the U. S. The Mediterranean Sea basin includes much of North Africa, east-central Africa, Southern, Central, and Eastern Europe, Turkey, and the areas of Israel, Lebanon. Just over 13% of the land in the world drains to the Pacific Ocean, the Indian Oceans drainage basin also comprises about 13% of Earths land. It drains the eastern coast of Africa, the coasts of the Red Sea and the Persian Gulf, the Indian subcontinent, Burma, antarctica comprises approximately eight percent of the Earths land. The five largest river basins, from largest to smallest, are the basins of the Amazon, the Río de la Plata, the Congo, the Nile, and the Mississippi. The three rivers that drain the most water, from most to least, are the Amazon, Ganga, endorheic drainage basins are inland basins that do not drain to an ocean. Around 18% of all land drains to endorheic lakes or seas or sinks, the largest of these consists of much of the interior of Asia, which drains into the Caspian Sea, the Aral Sea, and numerous smaller lakes. Some of these, such as the Great Basin, are not single drainage basins but collections of separate, in endorheic bodies of standing water where evaporation is the primary means of water loss, the water is typically more saline than the oceans. An extreme example of this is the Dead Sea, drainage basins have been historically important for determining territorial boundaries, particularly in regions where trade by water has been important

Kyrgyzstan
–
Kyrgyzstan, officially the Kyrgyz Republic, is a country in Central Asia. Landlocked and mountainous, Kyrgyzstan is bordered by Kazakhstan to the north, Uzbekistan to the west and southwest, Tajikistan to the southwest and its capital and largest city is Bishkek. Kyrgyzstans recorded history spans over 2,000 years, encompassing a variety of cultures and empires, ethnic Kyrgyz make up the majority of the countrys 5.7 million people, followed by significant minorities of Uzbeks and Russians. Kyrgyz is closely related to other Turkic languages, although Russian remains widely spoken and is the official language, the majority of the population are non-denominational Muslims. In addition to its Turkic origins, Kyrgyz culture bears elements of Persian, Mongolian and Russian influence. Kyrgyz is believed to have derived from the Turkic word for forty, in reference to the forty clans of Manas. Literally, Kyrgyz means We are forty, at the time, in the early 9th century AD, the Uyghurs dominated much of Central Asia, Mongolia, and parts of Russia and China. King, Scythians were early settlers in present-day Kyrgyzstan, the Kyrgyz state reached its greatest expansion after defeating the Uyghur Khaganate in 840 A. D. From the 10th century the Kyrgyz migrated as far as the Tian Shan range, in the twelfth century the Kyrgyz dominion had shrunk to the Altay Range and Sayan Mountains as a result of the Mongol expansion. With the rise of the Mongol Empire in the thirteenth century, the Kyrgyz peacefully became a part of the Mongol Empire in 1207. The descent of the Kyrgyz from the autochthonous Siberian population is confirmed on the hand by the recent genetic studies. Issyk Kul Lake was a stopover on the Silk Road, a route for traders, merchants. Kyrgyz tribes were overrun in the 17th century by the Mongols, in the century by the Manchurian Qing Dynasty. In the late century, the majority part of what is today Kyrgyzstan was ceded to Russia through two treaties between China and Russia. The territory, then known in Russian as Kirghizia, was incorporated into the Russian Empire in 1876. The Russian takeover was met with numerous revolts against Tsarist authority, in addition, the suppression of the 1916 rebellion against Russian rule in Central Asia caused many Kyrgyz later to migrate to China. Soviet power was established in the region in 1919. On 5 December 1936, the Kirghiz Soviet Socialist Republic was established as a republic of the Soviet Union

Tajikistan
–
Tajikistan, officially the Republic of Tajikistan, is a mountainous, landlocked country in Central Asia with an estimated 8 million people in 2013, and an area of 143,100 km2. It is bordered by Islamic Republic of Afghanistan to the south, the Republic of Uzbekistan to the west, the Kyrgyz Republic to the north, the Islamic Republic of Pakistan lies to the south, separated by the narrow Wakhan Corridor. Traditional homelands of Tajik people included present-day Tajikistan, Afghanistan and Uzbekistan, a civil war was fought almost immediately after independence, lasting from 1992 to 1997. Since the end of the war, newly established political stability, Tajikistan is a presidential republic consisting of four provinces. Most of Tajikistans 8 million people belong to the Tajik ethnic group, many Tajiks also speak Russian as their second language. Mountains cover more than 90% of the country and it has a transition economy that is highly dependent on remittances, aluminium and cotton production. Tajikistan means the Land of the Tajiks, the suffix -stan is Persian for place of or country and Tajik is, most likely, the name of a pre-Islamic tribe. Tajikistan appeared as Tadjikistan or Tadzhikistan in English prior to 1991 and this is due to a transliteration from the Russian, Таджикистан. In Russian, there is no single letter j to represent the phoneme /ʤ/ and дж, Tadzhikistan is the most common alternate spelling and is widely used in English literature derived from Russian sources. Tadjikistan is the spelling in French and can occasionally be found in English language texts, the way of writing Tajikistan in the Perso-Arabic script is. The earliest recorded history of the dates back to about 500 BCE when much, if not all. After the regions conquest by Alexander the Great it became part of the Greco-Bactrian Kingdom, northern Tajikistan was part of Sogdia, a collection of city-states which was overrun by Scythians and Yuezhi nomadic tribes around 150 BCE. The Silk Road passed through the region and following the expedition of Chinese explorer Zhang Qian during the reign of Wudi commercial relations between Han China and Sogdiana flourished. Sogdians played a role in facilitating trade and also worked in other capacities, as farmers, carpetweavers, glassmakers. Later the Hephthalite Empire, a collection of tribes, moved into the region. Central Asia continued in its role as a crossroads, linking China, the steppes to the north. It was temporarily under the control of the Tibetan empire and Chinese from 650–680, the Samanid Empire,819 to 999, restored Persian control of the region and enlarged the cities of Samarkand and Bukhara which became the cultural centres of Iran and the region was known as Khorasan. The Kara-Khanid Khanate conquered Transoxania and ruled between 999–1211, during Genghis Khans invasion of Khwarezmia in the early 13th century the Mongol Empire took control over nearly all of Central Asia

Turkmenistan
–
Turkmenistan has been at the crossroads of civilizations for centuries. In medieval times, Merv was one of the cities of the Islamic world and an important stop on the Silk Road. Annexed by the Russian Empire in 1881, Turkmenistan later figured prominently in the movement in Central Asia. In 1924, Turkmenistan became a constituent republic of the Soviet Union, Turkmen Soviet Socialist Republic, Turkmenistan possesses the worlds fourth largest reserves of natural gas resources. Most of the country is covered by the Karakum Desert, since 1993, citizens have received government-provided electricity, water and natural gas free of charge. Turkmenistan was ruled by President for Life Saparmurat Niyazov until his death in 2006, Gurbanguly Berdimuhamedow was elected president in 2007. According to Human Rights Watch, Turkmenistan remains one of the world’s most repressive countries, after suspending the death penalty, the use of capital punishment was formally abolished in the 2008 constitution. Historically inhabited by the Indo-Iranians, the history of Turkmenistan begins with its annexation by the Achaemenid Empire of Ancient Iran. In the 8th century AD, Turkic-speaking Oghuz tribes moved from Mongolia into present-day Central Asia, part of a powerful confederation of tribes, these Oghuz formed the ethnic basis of the modern Turkmen population. In the 10th century, the name Turkmen was first applied to Oghuz groups that accepted Islam, There they were under the dominion of the Seljuk Empire, which was composed of Oghuz groups living in present-day Iran and Turkmenistan. Turkmen soldiers in the service of the played a important role in the spreading of Turkic culture when they migrated westward into present-day Azerbaijan. In the 12th century, Turkmen and other tribes overthrew the Seljuk Empire, in the next century, the Mongols took over the more northern lands where the Turkmens had settled, scattering the Turkmens southward and contributing to the formation of new tribal groups. The sixteenth and eighteenth centuries saw a series of splits and confederations among the nomadic Turkmen tribes, by the 16th century, most of those tribes were under the nominal control of two sedentary Uzbek khanates, Khiva and Bukhoro. Turkmen soldiers were an important element of the Uzbek militaries of this period, in the 19th century, raids and rebellions by the Yomud Turkmen group resulted in that groups dispersal by the Uzbek rulers. According to Paul R. Spickard, Prior to the Russian conquest, Russian forces began occupying Turkmen territory late in the 19th century. From their Caspian Sea base at Krasnovodsk, the Russians eventually overcame the Uzbek khanates, in 1916 the Russian Empires participation in World War I resonated in Turkmenistan, as an anticonscription revolt swept most of Russian Central Asia. In 1924 the Turkmen Soviet Socialist Republic was formed from the tsarist province of Transcaspia, by the late 1930s, Soviet reorganization of agriculture had destroyed what remained of the nomadic lifestyle in Turkmenistan, and Moscow controlled political life. The Ashgabat earthquake of 1948 killed over 110,000 people, during the next half-century, Turkmenistan played its designated economic role within the Soviet Union and remained outside the course of major world events

Russia
–
Russia, also officially the Russian Federation, is a country in Eurasia. The European western part of the country is more populated and urbanised than the eastern. Russias capital Moscow is one of the largest cities in the world, other urban centers include Saint Petersburg, Novosibirsk, Yekaterinburg, Nizhny Novgorod. Extending across the entirety of Northern Asia and much of Eastern Europe, Russia spans eleven time zones and incorporates a range of environments. It shares maritime borders with Japan by the Sea of Okhotsk, the East Slavs emerged as a recognizable group in Europe between the 3rd and 8th centuries AD. Founded and ruled by a Varangian warrior elite and their descendants, in 988 it adopted Orthodox Christianity from the Byzantine Empire, beginning the synthesis of Byzantine and Slavic cultures that defined Russian culture for the next millennium. Rus ultimately disintegrated into a number of states, most of the Rus lands were overrun by the Mongol invasion. The Soviet Union played a role in the Allied victory in World War II. The Soviet era saw some of the most significant technological achievements of the 20th century, including the worlds first human-made satellite and the launching of the first humans in space. By the end of 1990, the Soviet Union had the second largest economy, largest standing military in the world. It is governed as a federal semi-presidential republic, the Russian economy ranks as the twelfth largest by nominal GDP and sixth largest by purchasing power parity in 2015. Russias extensive mineral and energy resources are the largest such reserves in the world, making it one of the producers of oil. The country is one of the five recognized nuclear weapons states and possesses the largest stockpile of weapons of mass destruction, Russia is a great power as well as a regional power and has been characterised as a potential superpower. The name Russia is derived from Rus, a state populated mostly by the East Slavs. However, this name became more prominent in the later history, and the country typically was called by its inhabitants Русская Земля. In order to distinguish this state from other states derived from it, it is denoted as Kievan Rus by modern historiography, an old Latin version of the name Rus was Ruthenia, mostly applied to the western and southern regions of Rus that were adjacent to Catholic Europe. The current name of the country, Россия, comes from the Byzantine Greek designation of the Kievan Rus, the standard way to refer to citizens of Russia is Russians in English and rossiyane in Russian. There are two Russian words which are translated into English as Russians

Iran, also known as Persia, officially the Islamic Republic of Iran, is a sovereign state in Western Asia. Comprising a land area of 1,648,195 km2, it is the second-largest country in the Middle East, with 82.8 million inhabitants, Iran is the worlds 17th-most-populous country. It is the country with both a Caspian Sea and an Indian Ocean coastline. The countrys central location in Eurasia and Western Asia, and its proximity to the Strait of Hormuz, Tehran is the countrys capital and largest city, as well as its leading economic and cultural center. Iran is the site of to one of the worlds oldest civilizations, the area was first unified by the Iranian Medes in 625 BC, who became the dominant cultural and political power in the region. The empire collapsed in 330 BC following the conquests of Alexander the Great, under the Sassanid Dynasty, Iran again became one of the leading powers in the world for the next four centuries. Beginning in 633 AD, Arabs conquered Iran and largely displaced the indigenous faiths of Manichaeism and Zoroastrianism by Islam, Iran became a major contributor to the Islamic Golden Age that followed, producing many influential scientists, scholars, artists, and thinkers. During the 18th century, Iran reached its greatest territorial extent since the Sassanid Empire, through the late 18th and 19th centuries, a series of conflicts with Russia led to significant territorial losses and the erosion of sovereignty. Popular unrest culminated in the Persian Constitutional Revolution of 1906, which established a monarchy and the countrys first legislative body. Following a coup instigated by the U. K. Growing dissent against foreign influence and political repression led to the 1979 Revolution, Irans rich cultural legacy is reflected in part by its 21 UNESCO World Heritage Sites, the third-largest number in Asia and 11th-largest in the world. Iran is a member of the UN, ECO, NAM, OIC. Its political system is based on the 1979 Constitution which combines elements of a democracy with a theocracy governed by Islamic jurists under the concept of a Supreme Leadership. A multicultural country comprising numerous ethnic and linguistic groups, most inhabitants are Shia Muslims, the largest ethnic groups in Iran are the Persians, Azeris, Kurds and Lurs. Historically, Iran has been referred to as Persia by the West, due mainly to the writings of Greek historians who called Iran Persis, meaning land of the Persians. As the most extensive interactions the Ancient Greeks had with any outsider was with the Persians, however, Persis was originally referred to a region settled by Persians in the west shore of Lake Urmia, in the 9th century BC. The settlement was then shifted to the end of the Zagros Mountains. In 1935, Reza Shah requested the international community to refer to the country by its native name, opposition to the name change led to the reversal of the decision, and Professor Ehsan Yarshater, editor of Encyclopædia Iranica, propagated a move to use Persia and Iran interchangeably

Aral, Kazakhstan
–
Aral, also known as Aralsk or Aralsk, is a small city in south-western Kazakhstan, located in the oblast of Kyzylorda. It serves as the center of Aral District. Aral was formerly a port and harbour city on the banks of the Aral Sea. In 1817, there was a village Alty-Kuduk near the present city of Aralsk and this is currently a railway passing-track in the southern part of the city. Since the 1870s, this was recorded as the Aralsky settlement, the development of Aralsk began when the Orenburg-Tashkent railway was being constructed. In 1905, the station was constructed and continues to operate. The official history of Aralsk began that same year, in 1905, Russian merchants organized large fishing companies and formed a joint-stock firm in Aralsk. This was the beginning of fishery in the Aral Sea and ship-building plants soon followed in Aralsk, after the Revolution, the station “Aralskoye more ” with the adjoining settlement received the name Aralsk. In 1938, Aralsk and the Aralsky district became a part of newly formed Kzyl-Orda oblast of Kazakh SSR, Aralsk is not to be confused with Fort Aralsk which was about 120km south. In 1847 Russia built Raimsk, later called Fort Aralsk, near the mouth of the Syr Darya, in either 1848 or 1853 or 1855 Raimsk was abandoned and Fort Aralsk moved upriver to Fort Number One, or Kazalinsk. Further upriver were forts No.2 and 3 which were the old Kokandi forts of Karmaktschy, Fort Aralsk was used to launch ships to map the Aral Sea and as a base to attack Ak Mechet. Aral has greatly diminished in population and socioeconomic significance, resulting in levels of unemployment. For the last 25 years it has not been possible to see the sea from the town, in less than 2 weeks, approximately 50,000 residents of Aral were vaccinated. Household quarantine of potentially exposed individuals was enacted, and hundreds were isolated in a facility at the edge of the city. All traffic in and out of the city was stopped, the original outbreak sickened ten people in Aral, of whom 3 died. Aral has a desert climate with cold winters and hot summers.

Royal Geographical Society
–
The Royal Geographical Society is the UKs learned society and professional body for geography, founded in 1830 for the advancement of geographical sciences. Today, it is the centre for geographers and geographical learning. The Society has over 16,500 members and its work reaches millions of people each year through publications, research groups, the Geographical Society of London was founded in 1830 under the name Geographical Society of London as an institution to promote the advancement of geographical science. It later absorbed the older African Association, which had been founded by Sir Joseph Banks in 1788, as well as the Raleigh Club and the Palestine Association. Like many learned societies, it had started as a club in London. Founding members of the Society included Sir John Barrow, Sir John Franklin, under the patronage of King William IV it later became known as The Royal Geographical Society and was granted its Royal Charter under Queen Victoria in 1859. From 1830 –1840 the RGS met in the rooms of the Horticultural Society in Regent Street, London and from 1854 -1870 at 15 Whitehall Place, London. In 1870, the Society finally found a home when it moved to 1 Savile Row, London – an address that became associated with adventure. The Society also used a lecture theatre in Burlington Gardens, London which was lent to it by the Civil Service Commission, however, the arrangements were thought to be rather cramped and squalid. A new impetus was given to the Societys affairs in 1911, with the election of Earl Curzon, the premises in Savile Row were sold and the present site, Lowther Lodge in Kensington Gore, was purchased for £100,000 and opened for use in April 1913. In the same year the Societys ban on women was lifted, Lowther Lodge was built in 1874 for the Hon William Lowther by Norman Shaw, one of the most outstanding domestic architects of his day. Extensions to the east wing were added in 1929, and included the New Map Room, the extension was formally opened by HRH the Duke of York at the Centenary Celebrations on 21 October 1930. The history of the Society was closely allied for many of its years with colonial exploration in Africa, the Indian subcontinent, the polar regions. It has been a key associate and supporter of many explorers and expeditions, including those of Darwin, Livingstone, Stanley, Scott, Shackleton, Hunt. The early history of the Society is inter-linked with the history of British Geography, exploration, information, maps, charts and knowledge gathered on expeditions was sent to the RGS, making up its now unique geographical collections. The Society published its first journal in 1831 and from 1855, accounts of meetings, in 1893, this was replaced by The Geographical Journal which is still published today. With the advent of a systematic study of geography, the Institute of British Geographers was formed in 1933, by some academic Society fellows. Its activities included organising conferences, field trips, seminars and specialist research groups and publishing the journal, the RGS and IBG co-existed for 60 years until 1992 when a merger was discussed

Karakalpakstan
–
Karakalpakstan, officially the Republic of Karakalpakstan is an autonomous republic within Uzbekistan. It occupies the northwestern end of Uzbekistan. The Republic of Karakalpakstan has an area of 160,000 square kilometres and its territory covers the classical land of Khwarezm, though in classical Persian literature the area was known as Kāt. From about 500 BC to 500 AD, the region of Karakalpakstan was an agricultural area supported by extensive irrigation. The Karakalpak people, who used to be nomadic herders and fishers, were first recorded in the 16th century, Karakalpakstan was ceded to the Russian Empire by the Khanate of Khiva in 1873. Under Soviet rule, it was an area within Russia before becoming part of Uzbekistan in 1936. The region was probably at its most prosperous in the 1960s and 1970s, today, however, the drainage of the Aral Sea has rendered Karakalpakstan one of Uzbekistans poorest regions. The region is suffering from drought, partly due to weather patterns. Crop failures have deprived about 48,000 people of their source of income. Karakalpakstan is now mostly desert and is located in western Uzbekistan near the Aral Sea and it has an area of 164,900 km² and is surrounded by desert. The Kyzyl Kum desert is located to the east and the Kara Kum desert is located to the south, a rocky plateau extends west to the Caspian Sea. The Republic of Karakalpakstan is formally sovereign and shares veto power over decisions concerning it with Uzbekistan, according to the constitution, relations between Karakalpakstan and Uzbekistan are regulated by treaties and agreements and any disputes are settled by way of reconciliation. Its right to secede is limited by the power of Uzbekistans legislature over any decision to secede. Their name means Black Hat, but Karakalpak culture was so lost through Sovietization that the meaning of the black hat is now unknown. The Karakalpak language is considered closer to Kazakh than to Uzbek, the language was written in a modified Cyrillic in Soviet times and in the Latin alphabet since 1996. Other than the capital Nukus, large cities include Xojeli, Taxiatosh, Shimbai, Konirat and Moynaq, the economy of the region used to be heavily dependent on fisheries in the Aral Sea. It is now supported by cotton, rice and melons, hydroelectric power from a large Soviet-built station on the Amu Darya is also important. The Amu Darya delta was once populated, and supported extensive irrigation based agriculture for thousands of years

Turkic languages
–
The Turkic languages are a language family of at least thirty-five languages, spoken by Turkic peoples from Southeastern Europe and the Mediterranean to Siberia and Western China. Turkic languages are spoken as a language by some 170 million people. The Turkic language with the greatest number of speakers is Turkish, spoken mainly in Anatolia and the Balkans, characteristic features of Turkish, such as vowel harmony, agglutination, and lack of grammatical gender, are universal within the Turkic family. Apparent similarities with the Uralic languages family even caused these families to be regarded as one for a time under the hypothesis of Ural-Altaic languages. Turkic languages are languages, have vowel harmony, extensive agglutination by means of suffixes, and lack of grammatical articles, noun classes. Subject–object–verb word order is universal within the family, the geographical distribution of Turkic-speaking peoples across Eurasia ranges from the North-East of Siberia to Turkey in the West, since the Ottoman era. The two groups shared a religion, Tengrism, and there exists a multitude of evident loanwords between Turkic languages and Mongolic languages, although the loans were bidirectional, today Turkic loanwords constitute the largest foreign component in Mongolian vocabulary. The most famous of these loanwords include lion, gold, the Compendium of the Turkic Dialects, written during the 11th century AD by Kaşgarlı Mahmud of the Kara-Khanid Khanate, constitutes an early linguistic treatment of the family. The Compendium is the first comprehensive dictionary of the Turkic languages and it mainly pertains to the Southwestern branch of the family. The earliest records of the language spoken by Volga Bulgars, the parent to todays Chuvash language, are dated to the 13th–14th centuries AD. With the Turkic expansion during the Early Middle Ages, Turkic languages, in the course of just a few centuries, spread across Central Asia, various terminologies from the Turkic languages have passed into Persian, Hindustani, Russian, Chinese, and to a lesser extent, Arabic. This has obscured the historical developments within each language and/or language group, the modern genetic classification schemes for Turkic are still largely indebted to Samoilovich. It is not clear when two major types of Turkic can be assumed to have actually diverged. With less certainty, the Southwestern, Northwestern, Southeastern and Oghur groups may further be summarized as West Turkic, the following isoglosses are traditionally used in the classification of the Turkic languages, Rhoticisation, e. g. in the last consonant of the word for nine *toqqız. This separates the Oghur branch, which exhibits /r/, from the rest of Turkic, in this case, rhoticisation refers to the development of *-/r/, *-/z/, and *-/d/ to /r/, *-/k/, *-/kh/ in this branch. See Antonov and Jacques on the debate concerning rhotacism and lambdacism in Turkic and this separates Khalaj as a peripheral language. The following table is based upon the classification presented by Lars Johanson The following is a brief comparison of cognates among the basic vocabulary across the Turkic language family. Also, there may be shifts in the meaning from one language to another, in some cases the form given is found only in some dialects of the language, or a loanword is much more common

Soviet Union
–
The Soviet Union, officially the Union of Soviet Socialist Republics was a socialist state in Eurasia that existed from 1922 to 1991. It was nominally a union of national republics, but its government. The Soviet Union had its roots in the October Revolution of 1917 and this established the Russian Socialist Federative Soviet Republic and started the Russian Civil War between the revolutionary Reds and the counter-revolutionary Whites. In 1922, the communists were victorious, forming the Soviet Union with the unification of the Russian, Transcaucasian, Ukrainian, following Lenins death in 1924, a collective leadership and a brief power struggle, Joseph Stalin came to power in the mid-1920s. Stalin suppressed all opposition to his rule, committed the state ideology to Marxism–Leninism. As a result, the country underwent a period of rapid industrialization and collectivization which laid the foundation for its victory in World War II and postwar dominance of Eastern Europe. Shortly before World War II, Stalin signed the Molotov–Ribbentrop Pact agreeing to non-aggression with Nazi Germany, in June 1941, the Germans invaded the Soviet Union, opening the largest and bloodiest theater of war in history. Soviet war casualties accounted for the highest proportion of the conflict in the effort of acquiring the upper hand over Axis forces at battles such as Stalingrad. Soviet forces eventually captured Berlin in 1945, the territory overtaken by the Red Army became satellite states of the Eastern Bloc. The Cold War emerged by 1947 as the Soviet bloc confronted the Western states that united in the North Atlantic Treaty Organization in 1949. Following Stalins death in 1953, a period of political and economic liberalization, known as de-Stalinization and Khrushchevs Thaw, the country developed rapidly, as millions of peasants were moved into industrialized cities. The USSR took a lead in the Space Race with Sputnik 1, the first ever satellite, and Vostok 1. In the 1970s, there was a brief détente of relations with the United States, the war drained economic resources and was matched by an escalation of American military aid to Mujahideen fighters. In the mid-1980s, the last Soviet leader, Mikhail Gorbachev, sought to reform and liberalize the economy through his policies of glasnost. The goal was to preserve the Communist Party while reversing the economic stagnation, the Cold War ended during his tenure, and in 1989 Soviet satellite countries in Eastern Europe overthrew their respective communist regimes. This led to the rise of strong nationalist and separatist movements inside the USSR as well, in August 1991, a coup détat was attempted by Communist Party hardliners. It failed, with Russian President Boris Yeltsin playing a role in facing down the coup. On 25 December 1991, Gorbachev resigned and the twelve constituent republics emerged from the dissolution of the Soviet Union as independent post-Soviet states

North Aral Sea
–
The North Aral Sea is the portion of the former Aral Sea that is fed by the Syr Darya River. It split from the South Aral Sea in 1986 as water levels dropped due to diversion for agriculture. The poorly built Dike Kokaral intended to contain the North Aral Sea and save its fisheries failed twice, since then, water levels have risen faster than expected and fish stocks have increased. Plans to build a dike to increase water levels further were due to begin in 2010. In 1986, due to a loss of water, the Aral Sea split into northern and southern parts. There is now an effort in Kazakhstan to save and replenish the North Aral Sea. As part of effort, a dam project was completed in 2005, in 2008. After the fall of the Soviet Union, the government of independent Kazakhstan decided to restore the lake fed by Syr Darya. In 2003, the lake was 30 m in depth and 2,550 km2 in area, by 2008 it had reached 42 m in depth and 3,300 km2 in area

Aralkum Desert
–
The Aralkum Desert is a desert that has appeared since 1960 on the seabed once occupied by the Aral Sea. It lies to the south and east of what remains of the Aral Sea in Uzbekistan and Kazakhstan. While the level of the Aral Sea has fluctuated over its existence, the severely reduced inflow subsequently caused the water level in the Aral Sea to drop. While the North Aral Sea is rising due to a dike, the South Aral Sea kept dropping, thus expanding the size of the desert, until 2010, the water level of the South Aral Sea then began to drop again, this time more severely. The sands of the Aralkum and the dust that originates from it contain pollutants, the deserts location on a powerful east-west airstream has resulted in pesticides in the dust being found in the blood of penguins in Antarctica. Aral dust has also found in the fields of Russia, the forests of Norway.

UNESCO
–
The United Nations Educational, Scientific and Cultural Organization is a specialized agency of the United Nations based in Paris. It is the heir of the League of Nations International Committee on Intellectual Cooperation, UNESCO has 195 member states and nine associate members. Most of its offices are cluster offices covering three or more countries, national and regional offices also exist. UNESCO pursues its objectives through five major programs, education, natural sciences, social/human sciences, culture and it is also a member of the United Nations Development Group. UNESCO and its mandate for international cooperation can be traced back to a League of Nations resolution on 21 September 1921, on 18 December 1925, the International Bureau of Education began work as a non-governmental organization in the service of international educational development. However, the work of predecessor organizations was largely interrupted by the onset of World War II. On 30 October 1943, the necessity for an organization was expressed in the Moscow Declaration, agreed upon by China, the United Kingdom, the United States. This was followed by the Dumbarton Oaks Conference proposals of 9 October 1944, a prominent figure in the initiative for UNESCO was Rab Butler, the Minister of Education for the United Kingdom. At the ECO/CONF, the Constitution of UNESCO was introduced and signed by 37 countries, the Preparatory Commission operated between 16 November 1945, and 4 November 1946—the date when UNESCOs Constitution came into force with the deposit of the twentieth ratification by a member state. The first General Conference took place between 19 November to 10 December 1946, and elected Dr. Julian Huxley to Director-General and this change in governance distinguished UNESCO from its predecessor, the CICI, in how member states would work together in the organizations fields of competence. In 1956, the Republic of South Africa withdrew from UNESCO claiming that some of the organizations publications amounted to interference in the racial problems. South Africa rejoined the organization in 1994 under the leadership of Nelson Mandela, UNESCOs early work in the field of education included the pilot project on fundamental education in the Marbial Valley, Haiti, started in 1947. This project was followed by missions to other countries, including, for example. In 1948, UNESCO recommended that Member States should make free primary education compulsory, in 1990, the World Conference on Education for All, in Jomtien, Thailand, launched a global movement to provide basic education for all children, youths and adults. Ten years later, the 2000 World Education Forum held in Dakar, Senegal, UNESCOs early activities in culture included, for example, the Nubia Campaign, launched in 1960. The purpose of the campaign was to move the Great Temple of Abu Simbel to keep it from being swamped by the Nile after construction of the Aswan Dam, during the 20-year campaign,22 monuments and architectural complexes were relocated. This was the first and largest in a series of campaigns including Mohenjo-daro, Fes, Kathmandu, Borobudur, the organizations work on heritage led to the adoption, in 1972, of the Convention concerning the Protection of the World Cultural and Natural Heritage. The World Heritage Committee was established in 1976 and the first sites inscribed on the World Heritage List in 1978, since then important legal instruments on cultural heritage and diversity have been adopted by UNESCO member states in 2003 and 2005

Memory of the World Programme
–
This recorded memory reflects the diversity of languages, people, and cultures. UNESCO, the agency responsible for the protection of the worlds cultural and natural heritage. To this end, the Memory of the World Programme was established with the aim of preserving and digitizing humanitys documentary heritage, the program is administered by the International Advisory Committee, whose 14 members are appointed by the UNESCO Director-General. The IAC is responsible for the formulation of policies, including the technical, legal and financial framework for the program. Technical Sub-Committee, Develops, regularly revises and promulgates information guides on the preservation of documentary heritage, the Memory of the World Register is a compendium of documents, manuscripts, oral traditions, audio-visual materials, library, and archival holdings of universal value. The program also has the goal of using state-of-the-art technologies to provide wider accessibility, any organization or individual can nominate a documentary item for inscription on the Register. During its meetings, the IAC examines the full documentation of the description, origin, world significance. The body uses a set of criteria in examining each of the nominations, Time, Absolute age, of itself, does not make a document significant, but every document is a creature of its time. Some documents are especially evocative of their time, which may have one of crisis. A document may represent new discovery or be the first of its kind, place, The place of its creation is a key attribute of its importance. It may be descriptive of physical environments, cities or institutions since vanished, people, The social and cultural context of its creation may reflect significant aspects of human behaviour, or of social, industrial, artistic or political development. It may capture the essence of great movements, transitions, advances or regression and it may reflect the impact of key individuals or groups. Subject and Theme, The subject matter may represent particular historical or intellectual developments in natural, social and human sciences, politics, ideology, sports and the arts. Social/Spiritual/Community Significance, This concept is another way of expressing the significance of a document or set of documents in terms of its spiritual or sacred values. It allows a community to demonstrate its emotional attachment to the document or documents for the way in which these contribute to that communitys identity. Application of this criterion must reflect living significance – the documentary heritage must have a hold on people who are alive today. Other matters that will also be taken into account for each nomination are, Rarity, integrity, Within the natural physical limitations of carrier survival, is it complete or partial. Has it been altered or damaged, threat, Is its survival in danger

Holocene
–
The Holocene is the geological epoch that began after the Pleistocene at approximately 11,700 years before present. The term Recent has often used as an exact synonym of Holocene. The Holocene is part of the Quaternary period and its name comes from the Ancient Greek words ὅλος and καινός, meaning entirely recent. It has been identified with the current warm period, known as MIS1, given these, a new term, Anthropocene, is specifically proposed and used informally only for the very latest part of modern history involving significant human impact. It is accepted by the International Commission on Stratigraphy that the Holocene started approximately 11,700 years ago, the epoch follows the Pleistocene and the last glacial period. The Holocene can be subdivided into five time intervals, or chronozones, based on climatic fluctuations, Preboreal, Boreal, Atlantic, Subboreal and they find a general correspondence across Eurasia and North America, though the method was once thought to be of no interest. The scheme was defined for Northern Europe, but the changes were claimed to occur more widely. The periods of the include a few of the final pre-Holocene oscillations of the last glacial period. Paleontologists have not defined any faunal stages for the Holocene, if subdivision is necessary, periods of human technological development, such as the Mesolithic, Neolithic, and Bronze Age, are usually used. However, the time periods referenced by these terms vary with the emergence of those technologies in different parts of the world, climatically, the Holocene may be divided evenly into the Hypsithermal and Neoglacial periods, the boundary coincides with the start of the Bronze Age in Europe. According to some scholars, a division, the Anthropocene, has now begun. Continental motions due to plate tectonics are less than a kilometre over a span of only 10,000 years, however, ice melt caused world sea levels to rise about 35 m in the early part of the Holocene. The sea level rise and temporary land depression allowed temporary marine incursions into areas that are now far from the sea, Holocene marine fossils are known, for example, from Vermont and Michigan. Other than higher-latitude temporary marine incursions associated with depression, Holocene fossils are found primarily in lakebed, floodplain. Holocene marine deposits along low-latitude coastlines are rare because the rise in sea levels during the period exceeds any likely tectonic uplift of non-glacial origin, post-glacial rebound in the Scandinavia region resulted in the formation of the Baltic Sea. The region continues to rise, still causing weak earthquakes across Northern Europe, the equivalent event in North America was the rebound of Hudson Bay, as it shrank from its larger, immediate post-glacial Tyrrell Sea phase, to near its present boundaries. Climate has been stable over the Holocene. It appears that this was influenced by the glacial ice remaining in the Northern Hemisphere until the later date

Caspian Sea
–
The Caspian Sea is the largest enclosed inland body of water on Earth by area, variously classed as the worlds largest lake or a full-fledged sea. It is in a basin located between Europe and Asia. It is bounded by Kazakhstan to the northeast, Russia to the northwest, Azerbaijan to the west, Iran to the south, the Caspian Sea lies to the east of the Caucasus Mountains and to the west of the vast steppe of Central Asia. In its northern part, the Caspian Depression lies 28 to 130 m below sea level, the sea bed in the southern part reaches as low as 1023 m below sea level, which is the second lowest natural depression on earth after Lake Baikal. The ancient inhabitants of its coast perceived the Caspian Sea as an ocean, probably because of its saltiness, the sea has a surface area of 371,000 km2 and a volume of 78,200 km3. It has a salinity of approximately 1. 2%, about a third of the salinity of most seawater, the word Caspian is derived from the name of the Caspi, an ancient people who lived to the southwest of the sea in Transcaucasia. Strabo wrote that to the country of the Albanians belongs also the territory called Caspiane, which was named after the Caspian tribe, as was also the sea, but the tribe has now disappeared. Moreover, the Caspian Gates, which is the name of a region in Irans Tehran province, the Iranian city of Qazvin shares the root of its name with that of the sea. In fact, the traditional Arabic name for the sea itself is Bahr al-Qazwin, in classical antiquity among Greeks and Persians it was called the Hyrcanian Ocean. In Persian antiquity, as well as in modern Iran, it is known as the دریای خزر, Daryā-e Khazar, ancient Arabic sources refer to it as Baḥr Gīlān meaning the Gilan Sea. Turkic languages refer to the lake as Khazar Sea, in Turkmen, the name is Hazar deňizi, in Azeri, it is Xəzər dənizi, and in modern Turkish, it is Hazar denizi. An exception is Kazakh, where it is called Каспий теңізі, old Russian sources call it the Khvalyn or Khvalis Sea after the name of Khwarezmia. In modern Russian, it is called Каспи́йское мо́ре, Kaspiyskoye more, the Caspian Sea, like the Black Sea, Namak Lake, and Lake Urmia, is a remnant of the ancient Paratethys Sea. It became landlocked about 5.5 million years ago due to tectonic uplift and a fall in sea level. Due to the current inflow of water, the Caspian Sea is a freshwater lake in its northern portions, and is most saline on the Iranian shore. Currently, the salinity of the Caspian is one third that of Earths oceans. The Caspian Sea is the largest inland body of water in the world, the coastlines of the Caspian are shared by Azerbaijan, Iran, Kazakhstan, Russia, and Turkmenistan. The Caspian is divided into three distinct regions, the Northern, Middle, and Southern Caspian

Uzboy
–
Now a dry river channel and a center for archaeological excavations, the Uzboy flowed some 750 kilometres, from a branch in the Amu Darya River via Sarykamysh Lake to the Caspian Sea. The Uzboy dried up, and the tribes which had inhabited the banks were abruptly dispersed. In the early 1950s, construction started to build a major irrigation canal roughly along the river bed of the former Uzboy. However, the project was abandoned soon after the death of Joseph Stalin in 1953, later on, Qaraqum Canal was constructed along a different, much more southerly. Uzboi Vallis on Mars is named after this river and this a summary of Glukhovskoy’s book of 1893, which probably needs updating. It seems that the Oxus River flowed into the Caspian Sea via the Uzboy River until the 9th century AD, at various times in the past one or more branches of the Oxus split off from the Oxus delta and flowed west into the fresh-water Sarykamysh Lake. This was drained south by the Uzboy River about 175 km to near Igdi where it turned and flowed about 290 km west, there was a large waterfall, a place called the Lion’s Jaw and at one point the river disappeared underground for some distance. All geographers, from the ancient Greeks to the early Arabs, reported that the Oxus flowed into the Caspian, from the 10th to the 13th centuries there are no reports of a Caspian mouth. It is thought that a dam was built near the old capital of Konya-Urgench and we again hear of a Caspian mouth from about 1310 to 1575. It is possible that the main current shifted from the Aral to the Caspian, causing the Caspian to rise, there may have been a significant population along the Uzboy and farmland in what were later the marshes at the north end of the Oxus delta. It seems that about 1575 the east branch of the Oxus cut through some hills causing the current to shift to the Aral Sea. Also a dam was built near the old site to retain the remaining water and this not only blocked the Uzboy but caused the Sarikamish to slowly dry up. Peter the Great heard that it would be possible to destroy the dam and send the Oxus into its old channel, thereby making a waterway from Moscow down the Volga and this led to the 1717 invasion, among other things. Around 1879 Russia sent expeditions to survey the old channel. Glukhovskoy thought that a diversion would be practical. Either the Sarykamysh could be refilled, which would take about 15 years, the Uzboy would need to be cleared of sand in several places and some dams would be needed. The whole project would cost between 15 and 27 million rubles

Kyzylkum Desert
–
The Kyzylkum Desert, also spelled Qyzylqum, is the 16th largest desert in the world. Its name means Red Sand in Turkic languages and it is located in Central Asia in the doab between the rivers Amu Darya and Syr Darya, a region historically known as Transoxania or Sogdiana. Today it is divided between Kazakhstan, Uzbekistan and Turkmenistan, the territory consists mainly of an extensive plain at an altitude up to 300 m above sea level, with a number of depressions and highlands. Most of the area is covered with dunes, in the northwest large areas are covered with takirs. There are agricultural settlements along the rivers and in the oases, temperatures can be very high during the summer months, from mid-May to mid-September. Kerki, one inland city located on the banks of the Amu Darya River. Desert fauna include the Russian tortoise and a large lizard known as the Transcaspian or Desert Monitor, the Saiga Antelope also occasionally migrates through the northern part of the desert. There is a Kyzylkum nature reserve in Bukhara Province, founded in 1971, the area of the reserve amounts to 101,000 km2 and it is located on flood-land drained by the Amu-Darya close to the settlement Dargan Ata. Fauna include, the Bukhara Deer, Wild Boar, Common Pheasant, another reserve, Djeyran, is located 40 km to the south of Bukhara. The total area of this reserve is 51,450 km2 and it is a breeding centre for rare animals such as, the Goitered or Persian Gazelle Gazelle, Przewalskis Horse, the Turkmenian Kulan and Houbara Bustard. The reserve was founded in 1977 on the area in 5,131 ha. The Kyzylkum Desert has exposed rock formations that have yielded a number of fossils, tyrannosaurid, therizinosaurid, ostrich-mimic, oviraptorosaurian, troodontid, armored, duckbilled, and horned dinosaurs are also known from this rock unit. Paleontologists that have worked in area include J. David Archibald, Alexander Averianov, Sergei Kurzanov, Lev Nesov, Anatoly Riabinin, Anatoly Rozhdestvensky. The local population uses the large spaces of the Kyzylkum Desert as a pasture for livestock, the desert is well known for its deposits of gold, uranium, copper, aluminium and silver, natural gas and oil. The development of most the famous gold-field at Muruntau began in the early 1970s, the centres for the mining and smelting industry at the region are Navoi, Zarafshan city, Uchkuduk. The major industrial enterprises are, НГМК and the Uzbek U. S. A, the centres of the gas-production industry are Gazli and Mubarek

Pliocene
–
The Pliocene Epoch is the epoch in the geologic timescale that extends from 5.333 million to 2.58 million years BP. It is the second and youngest epoch of the Neogene Period in the Cenozoic Era, the Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch.588 to 1.806 million years ago, and is now included in the Pleistocene. As with other geologic periods, the geological strata that define the start and end are well identified but the exact dates of the start. The boundaries defining the Pliocene are not set at an easily identified worldwide event, the upper boundary was set at the start of the Pleistocene glaciations. The Pliocene was named by Sir Charles Lyell, the name comes from the Greek words πλεῖον and καινός and means roughly continuation of the recent, referring to the essentially modern marine mollusc faunas. H. W. Fowler called the term a regrettable barbarism, in the official timescale of the ICS, the Pliocene is subdivided into two stages. From youngest to oldest they are, Piacenzian Zanclean The Piacenzian is sometimes referred to as the Late Pliocene, in the system of North American Land Mammal Ages include Hemphillian, and Blancan. The Blancan extends forward into the Pleistocene, South American Land Mammal Ages include Montehermosan, Chapadmalalan and Uquian. In the Paratethys area the Pliocene contains the Dacian and Romanian stages, as usual in stratigraphy, there are many other regional and local subdivisions in use. In Britain the Pliocene is divided into the stages, Gedgravian, Waltonian, Pre-Ludhamian, Ludhamian, Thurnian, Bramertonian or Antian, Pre-Pastonian or Baventian, Pastonian and Beestonian. The exact correlations between these stages and the ICS stages is still a matter of detail. The formation of an Arctic ice cap is signaled by a shift in oxygen isotope ratios and ice-rafted cobbles in the North Atlantic. Mid-latitude glaciation was probably underway before the end of the epoch, the global cooling that occurred during the Pliocene may have spurred on the disappearance of forests and the spread of grasslands and savannas. Continents continued to drift, moving from positions possibly as far as 250 km from their present locations to positions only 70 km from their current locations, africas collision with Europe formed the Mediterranean Sea, cutting off the remnants of the Tethys Ocean. The border between the Miocene and the Pliocene is also the time of the Messinian salinity crisis, Sea level changes exposed the land-bridge between Alaska and Asia. Pliocene marine rocks are exposed in the Mediterranean, India. Elsewhere, they are exposed largely near shores, the change to a cooler, dry, seasonal climate had considerable impacts on Pliocene vegetation, reducing tropical species worldwide. Deciduous forests proliferated, coniferous forests and tundra covered much of the north, tropical forests were limited to a tight band around the equator, and in addition to dry savannahs, deserts appeared in Asia and Africa

Khwarezm
–
It was the center of the Iranian Khwarezmian civilization and a series of kingdoms such as the Persian Empire, whose capitals were Kath, Gurganj and – from the 16th century on – Khiva. Today Khwarezm belongs partly to Uzbekistan, partly to Kazakhstan and partly to Turkmenistan, Khwarezm has been known also as Chorasmia, Khwarezmia, Khwarizm, Khwarazm, Khorezm, Khoresm, Khorasam, Kharazm, Harezm, Horezm, and Chorezm. C. E. Bosworth, however, believes the Persian name to be made up of xor and zam, designating the land from which the sun rises, another view is that the Iranian compound stands for lowland from khar low and zam land. Khwarezm is indeed the lowest region in Central Asia, located on the delta of the Amu Darya on the shores of the Aral Sea. Some of the early scholars believed Khwarezm to be what ancient Avestic texts refer to as Airyanem Vaejah. These sources claim that Old Urgench, which was the capital of ancient Khwarezm for many years, was actually Ourva, the eighth land of Ahura Mazda mentioned in the Pahlavi text of Vendidad. Al-Biruni starts giving names only with the Afrighid line of Khwarazmshahs, having placed the ascension of Afrighids in 616 of the Seleucid era, like Soghdiana, Khwarezm was an expansion of the BMAC culture during the Bronze Age which later fused with Indo-Iranians during their migrations around 1000 BC. Early Iron Age states arose from this cultural exchange, ruled by the native Afrighid Dynasty. It was at point that Khwarezm entered the historical record with the Achamenid expansion. An East Iranian language, known as Khwarezmian language, was spoken in Khwarezm proper until soon after the Mongol invasion and it was closely related to Sogdian. In the very part of its history, the inhabitants of the area were from Iranian stock. Sometime before the Achaemenid king Cyrus the Greats death in 530 BC, while he was dying, he appointed his son Smerdis/Bardiya as the governor of the region, along with Bactriana, Carmania, and the other eastern provinces of the empire. And the Persian poet Ferdowsi mentions Persian cities like Afrasiab and Chach in abundance in his epic Shahnama, the kings emissary offered to lead Alexanders armies against his own enemies, west over the Caspian towards the Black Sea. Although largely independent during the Seleucid, Bactrian and Arsacid dynasties, it is known that Khwarezm, yaqut al-Hamawi verifies that Khwarezm was a regional capital of the Sassanid empire. It was also vassal kingdom during periods of Kushans, Hephthalites, the Afrighids were a native Chorasmian dynasty which ruled over the kingdom of Khwarezm from 305 until 995 A. D. Sometimes it was under Sassanid control, in 712 Khwarezm was conquered by the Arab Umayyads. In 995, they overthrew the Afrighids of Kath and themselves assumed the traditional title of Khwarazm-Shah. Briefly, the area was under Samanid suzerainty, before it passed to Mahmud of Ghazna in 1017, in the 12th century, the Khwarezmid Empire was founded and, in the early 13th century, ruled over all of Persia under the Shah ʿAlāʾ al-Dīn Muhammad II

Tang dynasty
–
The Tang dynasty was an imperial dynasty of China preceded by the Sui dynasty and followed by the Five Dynasties and Ten Kingdoms period. It is generally regarded as a point in Chinese civilization. Its territory, acquired through the campaigns of its early rulers, rivaled that of the Han dynasty. The dynasty was founded by the Lǐ family, who seized power during the decline, the dynasty was briefly interrupted when Empress Wu Zetian seized the throne, proclaiming the Second Zhou dynasty and becoming the only Chinese empress regnant. In two censuses of the 7th and 8th centuries, the Tang records estimated the population by number of registered households at about 50 million people. Various kingdoms and states paid tribute to the Tang court, while the Tang also conquered or subdued several regions which it controlled through a protectorate system. Besides political hegemony, the Tang also exerted a powerful influence over neighboring states such as those in Korea, Japan. Like the previous Sui dynasty, the Tang dynasty maintained a service system by recruiting scholar-officials through standardized examinations and recommendations to office. This civil order was undermined by the rise of military governors known as jiedushi during the 9th century. Chinese culture flourished and further matured during the Tang era, it is considered the greatest age for Chinese poetry. Two of Chinas most famous poets, Li Bai and Du Fu, belonged to this age, as did many famous painters such as Han Gan, Zhang Xuan, there was a rich variety of historical literature compiled by scholars, as well as encyclopedias and geographical works. The adoption of the title Tängri Qaghan by the Tang Emperor Taizong in addition to his title as emperor was eastern Asias first simultaneous kingship, there were many notable innovations during the Tang, including the development of woodblock printing. Buddhism became an influence in Chinese culture, with native Chinese sects gaining prominence. However, Buddhism would later be persecuted by the state, subsequently declining in influence, although the dynasty and central government were in decline by the 9th century, art and culture continued to flourish. This family was known as the Longxi Li lineage, which includes the Tang poet Li Bai, the Tang Emperors also had Xianbei maternal ancestry, from Emperor Gaozu of Tangs Xianbei mother Duchess Dugu. He had prestige and military experience, and was a first cousin of Emperor Yang of Sui, Li Yuan rose in rebellion in 617, along with his son and his equally militant daughter Princess Pingyang, who raised and commanded her own troops. In winter 617, Li Yuan occupied Changan, relegated Emperor Yang to the position of Taishang Huang or retired emperor, and acted as regent to the puppet child-emperor, Emperor Gong of Sui. On the news of Emperor Yangs murder by General Yuwen Huaji on June 18,618, Li Yuan declared himself the emperor of a new dynasty, the Tang

China
–
China, officially the Peoples Republic of China, is a unitary sovereign state in East Asia and the worlds most populous country, with a population of over 1.381 billion. The state is governed by the Communist Party of China and its capital is Beijing, the countrys major urban areas include Shanghai, Guangzhou, Beijing, Chongqing, Shenzhen, Tianjin and Hong Kong. China is a power and a major regional power within Asia. Chinas landscape is vast and diverse, ranging from forest steppes, the Himalaya, Karakoram, Pamir and Tian Shan mountain ranges separate China from much of South and Central Asia. The Yangtze and Yellow Rivers, the third and sixth longest in the world, respectively, Chinas coastline along the Pacific Ocean is 14,500 kilometers long and is bounded by the Bohai, Yellow, East China and South China seas. China emerged as one of the worlds earliest civilizations in the basin of the Yellow River in the North China Plain.

The demonym, that is, the name for the people, Portuguese China is thought to derive from Persian Chīn, and perhaps ultimately from Sanskrit Cīna. Cīna was first used in early Hindu scripture, including the Mahābhārata, there are, however, other suggestions for the derivation of China. The official name of the state is the Peoples Republic of China. The shorter form is China Zhōngguó, from zhōng and guó and it was then applied to the area around Luoyi during the Eastern Zhou and then to Chinas Central Plain before being used as an occasional synonym for the state under the Qing

The Ural River is conventionally considered part of the boundary between the continents of Europe and Asia, the river begins at the slopes of the Kruglaya Mountain of the Uraltau mountain ridge in South Ural, on the territory of the Uchalinsky District of Bashkortostan. There it has a width of 60 to 80 metres. It then falls into the Yaik Swamp and after exiting it widens up to 5 kilometres, below Verkhneuralsk, its flow is characteristic of a flatland river, there it enters Chelyabinsk and Orenburg Oblasts. From Magnitogorsk to Orsk its banks are steep and rocky and the bottom has many rifts, after Orsk, the river abruptly turns west and flows through a 45-kilometre long canyon in the Guberlinsk Mountains. After Uralsk, it flows north to south, through the territory of West Kazakhstan Province. There, the river widens and has lakes and ducts. Near the mouth, it splits into the Yaik and Zolotoy distributaries, the Yaik distributary is shallow, with almost no trees on the shores, and is rich in fish, whereas Zolotoy is deeper and is navigable. Ural River has a spectacular tree-like shape of the delta and this type of delta forms naturally in the slow rivers which deliver a great deal of sediments and flow into a quiet sea. In the delta,13.5 kilometres from the mouth of the Zolotoy distributary lies Shalyga Island, which is 2.5 kilometres long, with heights of 1 to 2 metres and maximum widths of 0.3 kilometres. The tributaries, in order going upstream, are Kushum, Derkul, Chagan, Irtek, Utva, Ilek, Bolshaya Chobda, Kindel, Sakmara, Salmys, Or, the entire length of the Ural River is considered the Europe-Asia boundary by most authoritative sources.

During the floods, the river widens to above 10 kilometres near Uralsk, water level is highest in later April upstream and in May downstream. Its fluctuation is 3 to 4 metres in the stream,9 to 10 metres in the middle of the river. The average water discharge is 104 cubic metres per second near Orenburg, and 400 cubic metres per second at the Kushum village, the maximum discharge is 14,000 cubic metres per second and the minimum is 1.62 cubic metres per second. Average turbidity is 280 grams per cubic metre at Orenburg and 290 grams per cubic metre near Kushum, the river freezes at the source in early November and in the middle and lower reaches in late November. It opens in the lower reaches in late March and in early April in the upper reaches, the ice drift is relatively short
