Turkey
–
Turkey, officially the Republic of Turkey, is a transcontinental country in Eurasia, mainly in Anatolia in Western Asia, with a smaller portion on the Balkan peninsula in Southeast Europe. Turkey is a democratic, secular, unitary, parliamentary republic with a cultural heritage. The country is encircled by seas on three sides, the Aegean Sea is to the west, the Black Sea to the north, and the Mediterranean Sea to the south. The Bosphorus, the Sea of Marmara, and the Dardanelles, Ankara is the capital while Istanbul is the countrys largest city and main cultural and commercial centre. Approximately 70-80% of the countrys citizens identify themselves as ethnic Turks, other ethnic groups include legally recognised and unrecognised minorities. Kurds are the largest ethnic minority group, making up approximately 20% of the population, the area of Turkey has been inhabited since the Paleolithic by various ancient Anatolian civilisations, as well as Assyrians, Greeks, Thracians, Phrygians, Urartians and Armenians. After Alexander the Greats conquest, the area was Hellenized, a process continued under the Roman Empire. The Seljuk Sultanate of Rûm ruled Anatolia until the Mongol invasion in 1243, the empire reached the peak of its power in the 16th century, especially during the reign of Suleiman the Magnificent. During the war, the Ottoman government committed genocides against its Armenian, Assyrian, following the war, the conglomeration of territories and peoples that formerly comprised the Ottoman Empire was partitioned into several new states. Turkey is a member of the UN, an early member of NATO. Turkeys growing economy and diplomatic initiatives have led to its recognition as a regional power while her location has given it geopolitical, the name of Turkey is based on the ethnonym Türk. The first recorded use of the term Türk or Türük as an autonym is contained in the Old Turkic inscriptions of the Göktürks of Central Asia, the English name Turkey first appeared in the late 14th century and is derived from Medieval Latin Turchia. Similarly, the medieval Khazar Empire, a Turkic state on the shores of the Black. The medieval Arabs referred to the Mamluk Sultanate as al-Dawla al-Turkiyya, the Ottoman Empire was sometimes referred to as Turkey or the Turkish Empire among its European contemporaries. The Anatolian peninsula, comprising most of modern Turkey, is one of the oldest permanently settled regions in the world, various ancient Anatolian populations have lived in Anatolia, from at least the Neolithic period until the Hellenistic period. Many of these peoples spoke the Anatolian languages, a branch of the larger Indo-European language family, in fact, given the antiquity of the Indo-European Hittite and Luwian languages, some scholars have proposed Anatolia as the hypothetical centre from which the Indo-European languages radiated. The European part of Turkey, called Eastern Thrace, has also been inhabited since at least forty years ago. It is the largest and best-preserved Neolithic site found to date, the settlement of Troy started in the Neolithic Age and continued into the Iron Age

Eastern Anatolia Region
–
The Eastern Anatolia Region is a geographical region of Turkey. The region and the name Doğu Anadolu Bölgesi were first defined at the First Geography Congress in 1941 and it has the highest average altitude, largest geographical area, and lowest population density of all regions of Turkey. Prior to getting its current name by the Turkish state, most of the region was part of the Six Armenian provinces in the known as the Armenian Highlands. After the Armenian Genocide, the geopolitical term Eastern Anatolia was created to replace what had historically been known as Western Armenia, starting from 1880 the name Armenia was forbidden to be used in official Ottoman documents. The government of Sultan Abdul Hamid II replaced the name Armenia with such terms as Kurdistan or Anatolia, the Sublime Porte was trying to cover up the Armenian Question, if there was no Armenia, then there was no Armenian Question. The process of “nationalization” of toponyms was continued by the Kemalists, who were the successors of the Young Turks. Starting from 1923 the entire territory of Western Armenia was officially renamed “Eastern Anatolia”, in the 17th century when the Armenian Question was not as yet included into the international diplomacy agenda, the terms Anatolia or Eastern Anatolia were never used to indicate Armenia. Furthermore, the Islamic World Map of the 16th century and other Ottoman maps of the 18th and 19th centuries have clearly indicated Armenia on a territory as well as its cities. Armenia, together with its boundaries, was mentioned in the works of earlier Ottoman historians. Kâtip Çelebi, a famous Ottoman chronicler of the 17th century, had a chapter titled “About the Country Called Armenia” in his book Jihan Numa. When, however, this book was republished in 1957, its modern Turkish editor H. Selen changed this title into “Eastern Anatolia”. Osman Nuri, a historian of the half of the 19th century, mentions Armenia repeatedly in his three-volume Abdul Hamid. The word Anatolia means “sunrise” or “east” in Greek and this name was given to the Asia Minor peninsula approximately in the 5th or 4th centuries B. C. During the Ottoman era, the term Anadolou included the vilayets of Asia Minor with Kyotahia as its center. The numerous European, Ottoman, Armenian, Russian, Persian, Arabic and this testifies, inter alia, to the fact that even after the loss of its statehood the Armenian nation still constituted a majority in its homeland, which was recognized by Ottoman occupiers as well. The area of the region is 146,330 km², which comprises 18. 7% of the area of Turkey. The total population of the region is 6,100,000 and 5,906,565, the region has the second most rural population of Turkey after the Black Sea region. The migration level is high and population density is lower than the average for Turkey, the migration toward other Turkeys regions and toward foreign countries is higher than the natural population increase, a fact which is leading to a slight decline of the Regions population

Mount Ararat
–
Mount Ararat is a snow-capped and dormant compound volcano in the eastern extremity of Turkey. It consists of two volcanic cones, Greater Ararat, the highest peak in Turkey and the Armenian plateau with an elevation of 5,137 m. The Ararat massif is about 40 km in diameter, scholars agree the biblical mountains of Ararat do not refer to specifically Mt. Ararat. Nevertheless, it has perceived as the traditional resting place of Noahs Ark since the 11th century. It is the national symbol of Armenia and has been considered a sacred mountain by Armenians. It is featured prominently in Armenian literature and art and is an icon for Armenian irredentism, along with Noahs Ark, it is depicted on the coat of arms of Armenia. The first efforts to reach Ararats summit were made in the Middle Ages, however, it was not until 1829 when Friedrich Parrot and Khachatur Abovian, accompanied with four others, made the first recorded ascent. Mount Ararat forms a near-quadripoint between Turkey, Armenia, Azerbaijan and Iran and its summit is located some 16 km west of both the Iranian border and the border of the Nakhchivan exclave of Azerbaijan, and 32 km south of the Armenian border. Following the 1826–28 Russo-Persian War and the Treaty of Turkmenchay, the Persian controlled territory was ceded to the Russian Empire, Little Ararat became the point where the Turkish, Persian, and Russian imperial frontiers converged. The current international boundaries were formed throughout the 20th century, the mountain came under Turkish control during the 1920 Turkish–Armenian War. It formally became part of Turkey according to the 1921 Treaty of Moscow, in the late 1920s, Turkey crossed the Iranian border and occupied the eastern flank of Lesser Ararat as part of its effort to quash the Kurdish Ararat rebellion. The Kurdish rebels were using the area as a haven against the state in their uprising, Iran eventually agreed to cede the area to Turkey in a territorial exchange. The Iran-Turkey boundary skirts east of Lesser Ararat, the peak of the Ararat massif. Ararat is the Hebrew spelling of Urartu, a kingdom existed in the Armenian plateau in the 9th-6th centuries BC. The mountain is known as Ararat in European languages, however, none of the native peoples have traditionally referred to the mountain by that name. The traditional Armenian name is Masis, which is transliterated as Massis. However, nowadays, the terms Masis and Ararat are both widely, often interchangeably, used in Armenian, the peaks are referred to in plural as Մասիսներ Masisner. Greater Ararat is known as simply Masis or Մեծ Մասիս, while Lesser Ararat is known as Sis or Փոքր Մասիս

Lake Van
–
Lake Van, the largest lake in Turkey, lies in the far east of that country in the provinces of Van and Bitlis. It is a soda lake, receiving water from numerous small streams that descend from the surrounding mountains. Lake Van is one of the worlds largest endorheic lakes - a volcanic eruption blocked the outlet from the basin in ancient times. Although Lake Van has an altitude of 1,640 m in a region with harsh winters, its high salinity prevents most of it from freezing, and even the shallow northern section freezes only rarely. Lake Van is 119 kilometres across at its widest point, averaging a depth of 171 metres with a recorded depth of 451 metres. The lake surface lies 1,640 metres above sea level, Lake Van has an area of 3,755 km2 and a volume of 607 cubic kilometres. The western portion of the lake is deepest, with a large basin deeper than 400 m lying northeast of Tatvan, the eastern arms of the lake are shallower. The Van-Ahtamar portion shelves gradually, with a depth of about 250 m on its northwest side where it joins the rest of the lake. The Erciş arm is much shallower, mostly less than 50 m, the lake water is strongly alkaline and rich in sodium carbonate and other salts, which are extracted by evaporation and used as detergents. The lakes outlet was blocked at some time during the Pleistocene, now dormant, Nemrut Dağı is close to the western shore of the lake, and another dormant stratovolcano, Süphan Dağı dominates the northern side of the lake. The water level of the lake has often altered dramatically, near Tatvan, investigation by Degens and others in the early 1980s determined that the highest lake levels had been during the last ice age, about 18,000 years ago. Approximately 9,500 years ago there was a drop to more than 300 metres below the present level. This was followed by an equally-dramatic rise around 6,500 years ago, similar-but-smaller fluctuations have been seen recently. The level of the rose by at least three metres during the 1990s, drowning much agricultural land, and seems to be rising again. The level rose approximately two meters in the ten years prior to 2004. As a deep lake with no outlet, Lake Van has accumulated great amounts of sediment washed in from surrounding plains and valleys, and occasionally deposited as ash from eruptions of nearby volcanoes. This layer of sediment is estimated to be up to 400 metres thick in places, in 1989 and 1990, an international team of geologists led by Dr. Stephan Kempe from the University of Hamburg retrieved ten sediment cores from depths up to 446 m. Although these cores only penetrated the first few meters of sediment, litt expects to find that Lake Van stores the climate history of the last 800,000 years—an incomparable treasure house of data which we want to tap for at least the last 500,000 years

River mouth
–
A river mouth is the part of a river where the river flows into a larger river, a lake, a reservoir or an ocean. The water from a river can enter the body in a variety of different ways. The motion of the river mainly depends on the density of the river compared to the receiving water and any ambient motion in the receiving water. If the river water is denser than the surface of the receiving water, the river water will then either form an underflow or an interflow within the lake. Alongside these advective transports, inflowing water will also diffuse, at the mouth of a river, the change in flow condition can cause the river to drop any sediment it is carrying. This sediment deposition can generate a variety of landforms, such as deltas, sand bars, spits, many places in England take their names from their positions at the mouths of rivers, for example Plymouth, Sidmouth and Great Yarmouth.

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

Euphrates
–
The Euphrates is the longest and one of the most historically important rivers of Western Asia. Together with the Tigris, it is one of the two defining rivers of Mesopotamia, originating in eastern Turkey, the Euphrates flows through Syria and Iraq to join the Tigris in the Shatt al-Arab, which empties into the Persian Gulf. The Ancient Greek form Euphrátēs was borrowed from Old Persian Ufrātu, the Elamite name is ultimately derived from the Sumerian Buranuna, possibly through the Akkadian name. In Akkadian the river was similarly called Purattu, which has been perpetuated in Semitic languages, the Elamite, Akkadian, and possibly Sumerian forms are suggested to be from an unrecorded substrate language. The earliest references to the Euphrates come from texts found in Shuruppak and pre-Sargonic Nippur in southern Iraq. In these texts, written in Sumerian, the Euphrates is called Buranuna, the name could also be written KIB. NUN. or dKIB. NUN, with the prefix d indicating that the river was a divinity. In Sumerian, the name of the city of Sippar in modern-day Iraq was also a written UD. KIB. NUN, the Euphrates is the longest river of Western Asia. It emerges from the confluence of the Kara Su or Western Euphrates, the same figures are given by Isaev and Mikhailova. The length of the Shatt al-Arab, which connects the Euphrates, both the Kara Su and the Murat Su rise northwest from Lake Van at elevations of 3,290 metres and 3,520 metres amsl, respectively. At the location of the Keban Dam, the two rivers, now combined into the Euphrates, have dropped to an elevation of 693 metres amsl, from Keban to the Syrian–Turkish border, the river drops another 368 metres over a distance of less than 600 kilometres. The Euphrates receives most of its water in the form of rainfall and melting snow, discharge in these two months accounts for 36 percent of the total annual discharge of the Euphrates, or even 60–70 percent according to one source, while low runoff occurs in summer and autumn. The discharge regime of the Euphrates has changed dramatically since the construction of the first dams in the 1970s, data on Euphrates discharge collected after 1990 show the impact of the construction of the numerous dams in the Euphrates and of the increased withdrawal of water for irrigation. Average discharge at Hīt after 1990 has dropped to 356 cubic metres per second, the seasonal variability has equally changed. The pre-1990 peak volume recorded at Hīt was 7,510 cubic metres per second, the minimum volume at Hīt remained relatively unchanged, rising from 55 cubic metres per second before 1990 to 58 cubic metres per second afterward. In Syria, three rivers add their water to the Euphrates, the Sajur, the Balikh and the Khabur and these rivers rise in the foothills of the Taurus Mountains along the Syro–Turkish border and add comparatively little water to the Euphrates. The Sajur is the smallest of these tributaries, emerging from two streams near Gaziantep and draining the plain around Manbij before emptying into the reservoir of the Tishrin Dam. The Balikh receives most of its water from a spring near Ayn al-Arus. In terms of length, drainage basin and discharge, the Khabur is the largest of these three and its main karstic springs are located around Ras al-Ayn, from where the Khabur flows southeast past Al-Hasakah, where the river turns south and drains into the Euphrates near Busayrah
