White water
–
The term is also loosely used to refer to less turbulent, but still agitated, flows. The term whitewater also has a meaning, applying to any river or creek itself that has a significant number of rapids. The term is used as an adjective describing boating on such rivers. Four factors, separately or in combination, can create rapids, gradient, constriction, obstruction, gradient, constriction and obstruction are streambed topography factors and are relatively consistent. Flow rate is dependent upon both seasonal variation in precipitation and snowmelt and upon release rates of upstream dams, streambed topography is the primary factor in creating rapids, and is generally consistent over time. The gradient of a river is the rate at which it loses elevation along its course and this loss determines the rivers slope, and to a large extent its rate of flow. Shallow gradients produce gentle, slow rivers while steep gradients are associated with raging torrents, constrictions can form a rapid when a rivers flow is forced into a narrower channel. This pressure causes the water to more rapidly and to react differently to riverbed events. As with hydraulics, the power of eddies increases with the flow rate, in large rivers with high flow rates next to an obstruction, eddy walls can occur. An eddy wall is formed when the height of the river is higher than the level of the water in the eddy behind the obstruction. A marked increase or decrease in flow can create a rapid, flow rate is typically measured in cubic metres per second, or in cubic feet per second, depending on the country. The most widely used grading system is the International Scale of River Difficulty, grade-VI rapids are sometimes downgraded to grade-V or V+ if they have been run successfully. Harder rapids are often portaged, a French term for carrying, a portaged rapid is where the boater lands and carries the boat around the hazard. A rapids grade is not fixed, since it may vary depending on the water depth. Although some rapids may be easier at high flows because features are covered or washed-out, high water usually makes rapids more difficult, at flood stage, even rapids which are usually easy can contain lethal and unpredictable hazards. Class 1, Very small rough areas, requires no maneuvering, Class 2, Some rough water, maybe some rocks, small drops, might require maneuvering. Class 3, Medium waves, maybe a 3–5 ft drop, Class 4, Whitewater, large waves, long rapids, rocks, maybe a considerable drop, sharp maneuvers may be needed. Class 5, Whitewater, large waves, continuous rapids, large rocks and hazards, maybe a large drop, often characterized by must make moves, i. e. failure to execute a specific maneuver at a specific point may result in serious injury or death

Rapids
–
Rapids are sections of a river where the river bed has a relatively steep gradient, causing an increase in water velocity and turbulence. Rapids are hydrological features between a run and a cascade, rapids are characterised by the river becoming shallower with some rocks exposed above the flow surface. As flowing water splashes over and around the rocks, air bubbles become mixed in with it and portions of the surface acquire a white colour, forming what is called whitewater. Rapids occur where the bed material is resistant to the erosive power of the stream in comparison with the bed downstream of the rapids. Very young streams flowing across solid rock may be rapids for much of their length, rapids cause water aeration of the stream or river resulting in better water quality. Rapids are categorized in classes, generally running from I to VI, a Class 5 rapid may be categorized as Class 5. 1-5.9. While class I rapids are easy to negotiate and require no maneuvering, river rafting sports is carried out where many rapids are there in the course

Nile
–
The Nile is a major north-flowing river in northeastern Africa. It is generally regarded as the longest river in the world, in particular, the Nile is the primary water source of Egypt and Sudan. The Nile has two tributaries, the White Nile and Blue Nile. The White Nile is considered to be the headwaters and primary stream of the Nile itself, the Blue Nile, however, is the source of most of the water and silt. The White Nile is longer and rises in the Great Lakes region of central Africa and it flows north through Tanzania, Lake Victoria, Uganda and South Sudan. The Blue Nile begins at Lake Tana in Ethiopia and flows into Sudan from the southeast, the two rivers meet just north of the Sudanese capital of Khartoum. The northern section of the river flows north almost entirely through the Sudanese desert to Egypt, then ends in a large delta, Egyptian civilization and Sudanese kingdoms have depended on the river since ancient times. Most of the population and cities of Egypt lie along those parts of the Nile valley north of Aswan, in the ancient Egyptian language, the Nile is called Ḥpī or Iteru, meaning river. In Coptic, the words piaro or phiaro meaning the river come from the ancient name. The English name Nile and the Arabic names en-Nîl and an-Nîl both derive from the Latin Nilus and the Ancient Greek Νεῖλος, beyond that, however, the etymology is disputed. One possible etymology derives it from a Semitic Nahal, meaning river, the standard English names White Nile and Blue Nile, to refer to the rivers source, derive from Arabic names formerly applied only to the Sudanese stretches which meet at Khartoum. Above Khartoum, the Nile is also known as the White Nile, at Khartoum the river is joined by the Blue Nile. The White Nile starts in equatorial East Africa, and the Blue Nile begins in Ethiopia, both branches are on the western flanks of the East African Rift. The drainage basin of the Nile covers 3,254,555 square kilometers, the source of the Nile is sometimes considered to be Lake Victoria, but the lake has feeder rivers of considerable size. It is either the Ruvyironza, which emerges in Bururi Province, Burundi, or the Nyabarongo, the two feeder rivers meet near Rusumo Falls on the Rwanda-Tanzania border. Gish Abay is reportedly the place where the water of the first drops of the Blue Nile develop. The Nile leaves Lake Nyanza at Ripon Falls near Jinja, Uganda and it flows north for some 130 kilometers, to Lake Kyoga. For the remaining part it flows westerly through the Murchison Falls until it reaches the very northern shores of Lake Albert where it forms a significant river delta

Aswan
–
Aswan, formerly spelled Assuan, is a city in the south of Egypt, the capital of the Aswan Governorate. Aswan is a market and tourist centre located just north of the Aswan Dams on the east bank of the Nile at the first cataract. The modern city has expanded and includes the separate community on the island of Elephantine. Aswan is the ancient city of Swenett, which in antiquity was the town of Ancient Egypt facing the south. Swenett is supposed to have derived its name from an Egyptian goddess with the same name, the ancient name of the city also is said to be derived from the Egyptian symbol for trade, or market. The city stood upon a peninsula on the bank of the Nile, immediately below the first cataract of the flowing waters. Navigation to the delta was possible from this location without encountering a barrier, the stone quarries of ancient Egypt located here were celebrated for their stone, and especially for the granitic rock called Syenite. They lie on either bank of the Nile, and a road,6.5 km in length, was cut beside them from Syene to Philae, Swenett was equally important as a military station as a place of traffic. Under every dynasty it was a town, and here tolls. Around 330, the legion stationed here received a bishop from Alexandria, the city is mentioned by numerous ancient writers, including Herodotus, Strabo, Stephanus of Byzantium, Ptolemy, Pliny the Elder, Vitruvius, and it appears on the Antonine Itinerary. It also is mentioned in the Book of Ezekiel and the Book of Isaiah, the latitude of the city that would become Aswan – located at 24° 5′ 23″ – was an object of great interest to the ancient geographers. They believed that it was seated immediately under the tropic, and that on the day of the summer solstice and they noted that the suns disc was reflected in a well at noon. However, Eratosthenes used this information together with measurements of the length on the solstice at Alexandria to perform the first known calculation of the circumference of the Earth. The Nile is nearly 650 m wide above Aswan, from this frontier town to the northern extremity of Egypt, the river flows for more than 1,200 km without bar or cataract. The voyage from Aswan to Alexandria usually took 21 to 28 days in favourable weather, Aswan has a hot desert climate like the rest of Egypt. Aswan and Luxor have the hottest summer days of any city in Egypt, Aswan is one of the hottest, sunniest and driest cities in the world. Averages high temperatures are consistently above 40 °C during summer while averages low temperatures remain above 25 °C, summers are long, prolonged and extremely hot. Averages high temperatures remain above 23 °C during the coldest month of the year while averages low temperatures remain above 8 °C, winters are short, brief and extremely warm

Khartoum
–
Khartoum is the capital and second largest city of Sudan and the state of Khartoum. It is located at the confluence of the White Nile, flowing north from Lake Victoria, the location where the two Niles meet is known as al-Mogran. The main Nile continues to north towards Egypt and the Mediterranean Sea. The origin of the word, Khartoum, is uncertain, one theory argues that khartoum is derived from Arabic khurṭūm, probably referring to the narrow strip of land extending between the Blue and White Niles. Some scholars speculate that the word derives from the Nubian word, Agartum, other Beja scholars suggest Khartoum is derived from the Beja word, Hartoom. Additionally, the dream interpreting magicians in Genesis 41,8 are referred to as חַרְטֻמֵּ֥י, suggesting that in ancient times the word already existed. In 1821, Khartoum was established 24 kilometres north of the ancient city of Soba, by Ibrahim Pasha, the son of Egypts ruler, Muhammad Ali Pasha, who had just incorporated Sudan into his realm. Originally, Khartoum served as an outpost for the Egyptian Army and it also became a focal point for the slave trade. Later, it became the center of Sudan and official capital. On 13 March 1884, troops loyal to the Mahdi Muhammad Ahmad started a siege of Khartoum, the siege ended in a massacre of the Anglo-Egyptian garrison. On 26 January 1885, the damaged city fell to the Mahdists. On 2 September 1898, Omdurman was the scene of the bloody Battle of Omdurman, in 1973, the city was the site of an anomalous hostage crisis in which members of Black September held 10 hostages at the Saudi Arabian embassy, five of them diplomats. The US ambassador, the US deputy ambassador, and the Belgian chargé daffaires were murdered, a 1973 United States Department of State document, declassified in 2006, concluded, The Khartoum operation was planned and carried out with the full knowledge and personal approval of Yasser Arafat. In 1977, the first oil pipeline between Khartoum and the Port of Sudan was completed, throughout the 1970s and 1980s, Khartoum was the destination for hundreds of thousands of refugees fleeing conflicts in neighboring nations such as Chad, Eritrea, Ethiopia, and Uganda. Many Eritrean and Ethiopian refugees assimilated into society, while others settled in large slums at the outskirts of the city, since the mid-1980s, large numbers of refugees from South Sudan and Darfur fleeing the violence of the Second Sudanese Civil War and Darfur conflict have settled around Khartoum. In 1991, Osama bin Laden purchased a house in the affluent al-Riyadh neighborhood of the city and he lived there until 1996, when he was banished from the country. The destruction of the factory produced diplomatic tension between the U. S. and Sudan, the factory ruins are now a tourist attraction. The sudden death of SPLA head and vice-president of Sudan, John Garang, the riots finally died down after Southern Sudanese politicians and tribal leaders sent strong messages to the rioters

Islet
–
An islet is a very small island. As suggested by its origin as islette, an Old French diminutive of isle, use of the term implies small size, but little attention is given to drawing an upper limit on its applicability. Cay or Key – an islet formed by the accumulation of sand deposits atop a reef Motu – A reef islet formed by broken coral and sand. River island – A small islet within the current of a river, rock – A rock, in the sense of a type of islet, is an uninhabited landform composed of rock, lying offshore, and having at most minimal vegetation. Sandbar – An exposed sandbar is another type of islet, Sea stack – A thin, vertical landform jutting out of a body of water. Skerry – A small rocky island, usually defined to be too small for habitation, subsidiary islets – A more technical application is to small land features, isolated by water, lying off the shore of a larger island. Likewise, any emergent land in an atoll is called an islet. Tidal island – Often small islands lie off the mainland of an area, being connected to it in low tide. In the Caribbean and West Atlantic, islets are often called cays or keys, rum Cay in the Bahamas and the Florida Keys off Florida are examples of islets. In the Channel Islands, they are identified by the suffix -hou from the Norse -holm. In Scotland and Ireland, they are often called inches, from the Gaelic innis, which originally meant island, in Ireland they are often termed skerries. In and around Polynesia, islets are widely known by the term motu, in and around the River Thames in England, small islands are known as aits or eyots. One long-term dispute over the status of such an islet was that of Snake Island, there are thousands of islets on Earth, approximately 24,000 islands and islets in the Stockholm archipelago alone. The following is a list of example islets from around the world, Islands or Rocks, Is that the Real Question. The Treatment of Islands in the Delimitation of Maritime Boundaries, in Myron H.

Egypt
–
Egypt, officially the Arab Republic of Egypt, is a transcontinental country spanning the northeast corner of Africa and southwest corner of Asia by a land bridge formed by the Sinai Peninsula. Egypt is a Mediterranean country bordered by the Gaza Strip and Israel to the northeast, the Gulf of Aqaba to the east, the Red Sea to the east and south, Sudan to the south, and Libya to the west. Across the Gulf of Aqaba lies Jordan, and across from the Sinai Peninsula lies Saudi Arabia, although Jordan and it is the worlds only contiguous Afrasian nation. Egypt has among the longest histories of any country, emerging as one of the worlds first nation states in the tenth millennium BC. Considered a cradle of civilisation, Ancient Egypt experienced some of the earliest developments of writing, agriculture, urbanisation, organised religion and central government. One of the earliest centres of Christianity, Egypt was Islamised in the century and remains a predominantly Muslim country. With over 92 million inhabitants, Egypt is the most populous country in North Africa and the Arab world, the third-most populous in Africa, and the fifteenth-most populous in the world. The great majority of its people live near the banks of the Nile River, an area of about 40,000 square kilometres, the large regions of the Sahara desert, which constitute most of Egypts territory, are sparsely inhabited. About half of Egypts residents live in areas, with most spread across the densely populated centres of greater Cairo, Alexandria. Modern Egypt is considered to be a regional and middle power, with significant cultural, political, and military influence in North Africa, the Middle East and the Muslim world. Egypts economy is one of the largest and most diversified in the Middle East, Egypt is a member of the United Nations, Non-Aligned Movement, Arab League, African Union, and Organisation of Islamic Cooperation. Miṣr is the Classical Quranic Arabic and modern name of Egypt. The name is of Semitic origin, directly cognate with other Semitic words for Egypt such as the Hebrew מִצְרַיִם, the oldest attestation of this name for Egypt is the Akkadian

Aswan Low Dam
–
The Aswan Low Dam or Old Aswan Dam is a gravity masonry buttress dam on the Nile River in Aswan, Egypt. The dam was built at the former first cataract of the Nile, when initially constructed between 1899 and 1902, nothing of its scale had ever been attempted, on completion, it was the largest masonry dam in the world. The dam was designed to provide storage of floodwater and augment dry season flows to support greater irrigation development. These heightenings still did not meet demands and in 1946 it was nearly over-topped in an effort to maximize pool elevation. This led to the investigation and construction of the Aswan High Dam 6 kilometres upstream, after his field work convinced him of the impracticality of this scheme, and fearing the Caliphs anger, he feigned madness. He was kept under house arrest from 1011 until al-Hakims death in 1021, following their 1882 invasion and occupation of Egypt, the British began construction of the first dam across the Nile in 1898. Construction lasted until 1902, and it was opened on 10 December 1902, by HRH the Duke of Connaught, capital and financing were furnished by Ernest Cassel. The dam was constructed of masonry and faced with red ashlar granite. When constructed, the Old Aswan Dam was the largest masonry dam in the world, at the time of its construction, nothing of such scale had ever been attempted. The first phase was supervised by Sir Benjamin Baker, though much of the work was undertaken by Murdoch MacDonald. With its final raising, the dam is 1,950 metres in length, with a crest level 36 metres above the original riverbed, the dam provides the main route for traffic between the city and the airport. With the construction of the High Dam upstream, the Old Dams ability to pass the floods sediments was lost, the previous Old Dam reservoir level was also lowered and now provides control of tailwater for the High Dam. The Aswan Low Dam supports two hydroelectric plants, Aswan I and Aswan II. Aswan I contains 7 X40 megawatts generators with Kaplan turbines for a capacity of 280 megawatts and is located west of the dam. Aswan II contains 4 x 67.5 megawatts generators for a capacity of 270 megawatts and is located at the toe of the dam.

Sudan
–
Sudan, also known as North Sudan since South Sudans independence and officially the Republic of the Sudan, is a country in Northern Africa. It is the third largest country in Africa, the River Nile divides the country into eastern and western halves. Before the Sudanese Civil War, South Sudan was part of Sudan, Sudan was home to numerous ancient civilizations, such as the Kingdom of Kush, Kerma, Nobatia, Alodia, Makuria, Meroë and others, most of which flourished along the Nile. During the pre-dynastic period Nubia and Nagadan Upper Egypt were identical, by virtue of its proximity to Egypt, the Sudan participated in the wider history of the Near East inasmuch as it was Christianized by the 6th century, and Islamized in the 15th. As a result of Christianization, the Old Nubian language stands as the oldest recorded Nilo-Saharan language, Sudan was the largest country in Africa and the Arab world until 2011, when South Sudan separated into an independent country, following an independence referendum. Sudan is now the third largest country in Africa and also the third largest country in the Arab world and its capital is Khartoum, the political, cultural and commercial centre of the nation. It is a representative democratic federal republic. The politics of Sudan are regulated by an organization called the National Assembly. The Sudanese legal system is based on Islamic law, the countrys place name Sudan is a name given to a geographical region to the south of the Sahara, stretching from Western Africa to eastern Central Africa. The name derives from the Arabic bilād as-sūdān, or the lands of the Blacks, during the fifth millennium BC migrations from the drying Sahara brought neolithic people into the Nile Valley along with agriculture. The population that resulted from this cultural and genetic mixing developed social hierarchy over the centuries become the Kingdom of Kush at 1700 BC. The Kingdom of Kush was an ancient Nubian state centered on the confluences of the Blue Nile and White Nile, and the Atbarah River and it was established after the Bronze Age collapse and the disintegration of the New Kingdom of Egypt, centered at Napata in its early phase. After King Kashta invaded Egypt in the eighth century BC, the Kushite kings ruled as pharaohs of the Twenty-fifth Dynasty of Egypt for a century before being defeated and driven out by the Assyrians. At the height of their glory, the Kushites conquered an empire that stretched from what is now known as South Kordofan all the way to the Sinai, pharaoh Piye attempted to expand the empire into the Near East, but was thwarted by the Assyrian king Sargon II. Sennacheribs successor Esarhaddon went further, and invaded Egypt itself, deposing Taharqa, Taharqa fled back to his homeland where he died two years later. Egypt became an Assyrian colony, however, king Tantamani, after succeeding Taharqa, Esarhaddon died while preparing to leave the Assyrian capital of Nineveh in order to eject him. However, his successor Ashurbanipal sent an army into southern Egypt and routed Tantamani. During Classical Antiquity, the Nubian capital was at Meroë, in ancient Greek geography, the Meroitic kingdom was known as Ethiopia

Nubia
–
Nubia is a region along the Nile river located in what is today northern Sudan and southern Egypt. It was the seat of one of the earliest civilizations of ancient Africa, with a history that can be traced from at least 2000 B. C. onward, and was home to one of the African empires. Nubia was again united within Ottoman Egypt in the 19th century, the name Nubia is derived from that of the Noba people, nomads who settled the area in the 4th century following the collapse of the kingdom of Meroë. The Noba spoke a Nilo-Saharan language, ancestral to Old Nubian, Old Nubian was mostly used in religious texts dating from the 8th and 15th centuries AD. Before the 4th century, and throughout classical antiquity, Nubia was known as Kush, or, in Classical Greek usage, until at least 1970, the Birgid language was spoken north of Nyala in Darfur, but is now extinct. Nubia was divided into two regions, Upper and Lower Nubia, so called because of their location in the Nile river valley. Early settlements sprouted in both Upper and Lower Nubia, Egyptians referred to Nubia as Ta-Seti, or The Land of the Bow, since the Nubians were known to be expert archers. Modern scholars typically refer to the people from this area as the “A-Group” culture, fertile farmland just south of the Third Cataract is known as the “pre-Kerma” culture in Upper Nubia, as they are the ancestors. The Neolithic people in the Nile Valley likely came from Sudan, as well as the Sahara, by the 5th millennium BC, the people who inhabited what is now called Nubia participated in the Neolithic revolution. Saharan rock reliefs depict scenes that have been thought to be suggestive of a cult, typical of those seen throughout parts of Eastern Africa. Megaliths discovered at Nabta Playa are early examples of what seems to be one of the worlds first astronomical devices, around 3500 BC, the second Nubian culture, termed the A-Group, arose. It was a contemporary of, and ethnically and culturally similar to. The A-Group people were engaged in trade with the Egyptians and this trade is testified archaeologically by large amounts of Egyptian commodities deposited in the graves of the A-Group people. The imports consisted of gold objects, copper tools, faience amulets and beads, seals, slate palettes, stone vessels, and a variety of pots. Around 3300 BC, there is evidence of a kingdom, as shown by the finds at Qustul. The Nubian culture may have contributed to the unification of the Nile Valley. The earliest known depiction of the crown is on a ceremonial incense burner from Cemetery at Qustul in Lower Nubia. New evidence from Abydos, however, particularly the excavation of Cemetery U, around the turn of the protodynastic period, Naqada, in its bid to conquer and unify the whole Nile Valley, seems to have conquered Ta-Seti and harmonized it with the Egyptian state

Lake Nasser
–
Lake Nasser is a vast reservoir in southern Egypt and northern Sudan. It is one of the largest man-made lakes in the world, before construction, Sudan was against the building of Lake Nasser because it would encroach on land in the North, where the Nubian people lived. They would have to be resettled, in the end Sudans land near the area of Lake Nasser was mostly flooded by the lake. Strictly, Lake Nasser refers only to the larger portion of the lake that is in Egyptian territory. The lake is some 69 km long and 35 km across at its widest point and it covers a total surface area of 5,250 km2 and has a storage capacity of some 132 km3 of water. The lake was created as a result of the construction of the Aswan High Dam across the waters of the Nile between 1958 and 1970. The lake is named after Gamal Abdel Nasser, one of the leaders of the Egyptian Revolution of 1952, and the second President of Egypt and it was President Anwar Sadat who inaugurated the lake and dam in 1970. Egypt lacks the water it needs for agriculture, the Grand Ethiopian Renaissance Dam, currently being constructed in Ethiopia will most likely adversely affect Lake Nasser. While the Renaissance Dam will benefit Sudan and Ethiopia, it has caused tensions between Egypt and Sudan and Ethiopia, Egypt is worried that the new dam will stop the Nile River from adequately filling Lake Nasser. The water supply of Lake Nasser produces electricity and there is concern that water flowing into Lake Nasser will adversely affect Aswan Dams ability to generate electricity. There are pumping stations that control the water going into Lake Nasser, a fish enclosure was built in Lake Nasser. Fishing among tourists, especially for Nile perch, has become increasingly popular, the statue of Ramses II and others, at Abu Simbel Temple, look out over Lake Nasser and tourists can enjoy the view from their cruise ship.

Dar al-Manasir
–
Dar al-Manasir is the region of the Fourth Cataract, the most impassable of all rapids of the Nile. It is the homeland of the Arab tribe of the Manasir, still today the water rapids cannot be crossed by any large boats making the region accessible only via a sandy and rocky desert track. At the height of the Island of Muqrat the Nile river is blocked from its northward course taking a sharp turn SSW for 280 kilometres before continuing to flow north, Dar al-Manasir will be successively flooded by the Merowe Dam project. Dar al-Manasir is confined by the upstream living Rubatab tribe in the area of Abu Hamed, Dar al-Manasir is covering a distance of approximately 130 km along the Nile with most villages lined up along the left river bank called Western side. But the heart of Dar al-Manasir consists of 14 islands, twelve of them inhabited, al-Qanaweit, Shiri, Kidir, Sherari, Sur, Us, Tibit, Dumag, Buni, Arag, Dirbi. The climate is arid with a rainfall of about 50 mm in good years. The exact amount and spatial distribution of the precipitation during the season in the months of August until October is highly variable. The rainy season coincides with the season of the Nile. The Manasir pursue small scale agriculture in the vicinity of the Nile. Tiny pockets of alluvial sediments and the seasonally inundated riverside land are irrigated and cultivated. The most important cash crops of the region are dates, during good rainy seasons, in which grazing grounds are abundant, many male Manasir join members of their tribe in the adjacent Bayudah Desert. Politically Dar al-Manasir belongs to the River Nile state, the administrative centre with the only local run police station, branch of the Agricultural Bank and Secondary Schools for both sexes is Shiri on Shiri Island. Dar al-Manasir is among the most neglected areas in Northern Sudan, apart from basic educational institutions virtually no public infrastructure such as tarred roads, bridges or ferry boats and hospitals exist. The landscape, described by Innes as most barren and the most beautiful along the Nile, is rocky, picturesque, Dar al-Manasir with all its villages and agricultural land will be successively flooded in the coming months by the Merowe Dam project. Its residents are going to be moved, but the exact area is still not clear. Date cultivation in Dar al-Manasir Gray, T, in, Sudan Notes and Records, Vol.30, p. 120-121.

Merowe Dam
–
The Merowe Dam, also known as Merowe High Dam, Merowe Multi-Purpose Hydro Project or Hamdab Dam, is a large dam near Merowe Town in northern Sudan, about 350 kilometres north of the capital Khartoum. Its dimensions make it the largest contemporary hydropower project in Africa and it is situated on the river Nile, close to and inundating the 4th Cataract where the river divides into multiple smaller branches with large islands in between. Merowe is a city about 40 kilometres downstream from the site at Hamdab. The main purpose for building the dam was the generation of electricity, the dam has a length of about 9 kilometres and a crest height of up to 67 metres. The reservoir lake is planned to extend 174 kilometres upstream, the planners expect an annual electricity yield of 5.5 terawatt-hours, corresponding to an average load of 625 megawatts, or 50% of the rated load. The idea of a Nile dam at the 4th cataract is quite old, the authorities of the Anglo-Egyptian Sudan proposed it several times during the first half of the 20th century. It was supposed to equalize the large annual Nile flow fluctuations, create the possibility of growing cotton and provide flood protection for the lower Nile valley. After Sudan achieved independence in 1956, Egypt decided to control the flow of Nile water that reached its own territory by building a dam and creating a reservoir —the Aswan Dam and Nasser Lake. The Sudan military government under President Nimeiri revived the plan in 1979, the following decade saw international industry and planning offices busy, producing a total of four feasibility studies. However, insufficient funding and lack of investor interest effectively stalled the project at the planning stage and this appears to have changed fundamentally since the country started exporting oil in commercial quantities in the years 1999/2000. A greatly improved creditworthiness brought an influx of investment. The main contractors are, China International Water&Electric Corp, China National Water Resources and Hydropower Engineering Corp. River diversion and work on the dams began in early 2004. The left river channel was closed on 30 December 2005, the project timeline scheduled the reservoir impounding to start in mid-2006, the dam was inaugurated on March 3,2009, at which point the reservoir was full and all the hydro-electric generating capacity on-line. The total project cost is reported to be €1.2 billion and this can be subdivided into partial amounts for the construction work on the dam itself, its technical equipment and the necessary upgrade of the power transmission system. The electrification level in Sudan is very low, even by the standards of the region. In 2002, the average Sudanese consumed 58 kWh of electricity per year, i. e. about one fifteenth of their Egyptian neighbors to the north, and less than one hundredth of the OECD average. The capital Khartoum and a few large plantations account for more than two thirds of the electric power demand, while most of the rural areas are not connected to the national grid

Confluence
–
In geography, a confluence is the meeting of two or more bodies of water. The term is used to describe the meeting of tidal or other non-riverine bodies of water. A one-mile portion of the Industrial Canal in New Orleans accommodates the Gulf Intracoastal Waterway, niagara-on-the-Lake, Ontario, Canada is at the confluence of the Niagara River and Lake Ontario. The junction of the Green River and Colorado River forms the heart of Canyonlands National Park in Utahs Canyon Country, the Sangam, near Allahabad, India, where the sacred rivers Ganges and Yamuna meet to create one of the holiest places in Hinduism. The Ohio River is formed by the confluence of the Monongahela and Allegheny rivers, located in Pittsburgh, the Madison, Jefferson and Gallatin Rivers in Three Forks, Montana form the confluence of the Missouri River, one of the longest rivers in the United States. Kuala Lumpur, the capital of Malaysia, is at the confluence of the Gombak River and the Klang River. Passau known also as the Dreiflüssestadt, because the Danube River is joined there by the Inn River from the South, manaus, Brazil is on the Rio Negro near its confluence with the Amazon. It is the port and a hub for the regions extensive river system. Osijek, Croatia, is on the bank of the river Drava 25 km upstream of its confluence with the Danube. Belgrade, the capital of Serbia lies at the confluence of the Sava, the Hochelaga Archipelago, including the island and city of Montreal, is located at the confluence of the St. Lawrence River and Ottawa River in Quebec, Canada. Winnipeg, Canada, is at the confluence of the Red River, the area is referred to as The Forks by locals, and has been an important trade location for over 6000 years. The confluence of the rivers Danube and Morava in Devín on the border between Slovakia and Austria, triangle of Three Emperors, former tripoint in Europe. Cairo, Illinois, in the United States, where the Ohio River flows into the Mississippi River, St. Louis, Missouri, is built just south of the confluence of the Mississippi River and the Missouri River. Lyon, France is located on the confluence of the Saône and Rhone rivers, lytton, British Columbia, Canada, is located at the confluence of the muddy Fraser River and the clearer Thompson River. The confluence between the Franklin River and Gordon River in south-western Tasmania The confluence of the Snake and Columbia River at the Tri-Cities of Washington, the confluence of the rivers Pivka and Rak is one of the largest subterranean confluences in Europe.

Atbarah River
–
The Atbarah River in northeast Africa rises in northwest Ethiopia, approximately 50 km north of Lake Tana and 30 km west of Gondar. It flows about 805 km to the Nile in north-central Sudan and its tributary, the Tekezé River, is perhaps the true upper course of the Atbarah, as the Tekezé follows the longer course prior to the confluence of the two rivers in northeastern Sudan. The Atbarah is the last tributary of the Nile before it reaches the Mediterranean, for much of the year, it is little more than a stream. However during the season, the Atbarah rises some 18 ft above its normal level. At this time it forms a barrier between the northern and central districts of the Amhara Region of Ethiopia. Besides the Tekezé, important tributaries of the Atbarah include the Shinfa River which rises west of Lake Tana, the earliest surviving mention of the Atbarah is by Strabo, who called the river Astaboras. Other ancient authors mentioning the name include Agatharchides, who called it Astabaras, pliny the Elder provides a slightly different etymology of Astaboras, stating that in the language of the local people the name means water coming from the shades below. In 2010 started the building of a new dam, the Rumela and Burdana Dams, close to the junction of Upper Atbara. The new dams are located ca.80 km upstream from the Khashm El Girba Dam

Pluton
–
For the Australian gold mine see Plutonic Gold Mine In geology, a pluton is a body of intrusive igneous rock that is crystallized from magma slowly cooling below the surface of the Earth. Plutons include batholiths, stocks, dikes, sills, laccoliths, lopoliths, in practice, pluton usually refers to a distinctive mass of igneous rock, typically several kilometers in dimension, without a tabular shape like those of dikes and sills. Batholiths commonly are aggregations of plutons, examples of plutons include Denali, Cuillin, Cardinal Peak, Mount Kinabalu and Stone Mountain. The most common types in plutons are granite, granodiorite, tonalite, monzonite. Generally light colored, coarse-grained plutons of these compositions are referred to as granitoids, the term originated from Pluto, the classical god of the underworld.

Plate tectonics
–
The theoretical model builds on the concept of continental drift developed during the first few decades of the 20th century. The geoscientific community accepted plate-tectonic theory after seafloor spreading was validated in the late 1950s, the lithosphere, which is the rigid outermost shell of a planet, is broken up into tectonic plates. The Earths lithosphere is composed of seven or eight major plates, where the plates meet, their relative motion determines the type of boundary, convergent, divergent, or transform. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along plate boundaries. The relative movement of the plates typically ranges from zero to 100 mm annually, tectonic plates are composed of oceanic lithosphere and thicker continental lithosphere, each topped by its own kind of crust. Along convergent boundaries, subduction carries plates into the mantle, the material lost is balanced by the formation of new crust along divergent margins by seafloor spreading. In this way, the surface of the lithosphere remains the same. This prediction of plate tectonics is also referred to as the conveyor belt principle, earlier theories, since disproven, proposed gradual shrinking or gradual expansion of the globe. Tectonic plates are able to move because the Earths lithosphere has greater strength than the underlying asthenosphere. Lateral density variations in the result in convection. Plate movement is thought to be driven by a combination of the motion of the seafloor away from the ridge and drag, with downward suction. Another explanation lies in the different forces generated by forces of the Sun. The relative importance of each of these factors and their relationship to other is unclear. The outer layers of the Earth are divided into the lithosphere and asthenosphere and this is based on differences in mechanical properties and in the method for the transfer of heat. Mechanically, the lithosphere is cooler and more rigid, while the asthenosphere is hotter, in terms of heat transfer, the lithosphere loses heat by conduction, whereas the asthenosphere also transfers heat by convection and has a nearly adiabatic temperature gradient. The key principle of plate tectonics is that the lithosphere exists as separate and distinct tectonic plates, Plate motions range up to a typical 10–40 mm/year, to about 160 mm/year. The driving mechanism behind this movement is described below, tectonic lithosphere plates consist of lithospheric mantle overlain by either or both of two types of crustal material, oceanic crust and continental crust. Average oceanic lithosphere is typically 100 km thick, its thickness is a function of its age, as passes, it conductively cools
19.
Erosion
–
In earth science, erosion is the action of surface processes that remove soil, rock, or dissolved material from one location on the Earths crust, then transport it away to another location. Eroded sediment or solutes may be transported just a few millimetres, the rates at which such processes act control how fast a surface is eroded. Feedbacks are also possible between rates of erosion and the amount of eroded material that is carried by, for example. Processes of erosion that produce sediment or solutes from a place contrast with those of deposition, while erosion is a natural process, human activities have increased by 10-40 times the rate at which erosion is occurring globally. At well-known agriculture sites such as the Appalachian Mountains, intensive farming practices have caused erosion up to 100x the speed of the rate of erosion in the region. Excessive erosion causes both on-site and off-site problems, on-site impacts include decreases in agricultural productivity and ecological collapse, both because of loss of the nutrient-rich upper soil layers. In some cases, the end result is desertification. Off-site effects include sedimentation of waterways and eutrophication of bodies, as well as sediment-related damage to roads. Intensive agriculture, deforestation, roads, anthropogenic climate change and urban sprawl are amongst the most significant human activities in regard to their effect on stimulating erosion, however, there are many prevention and remediation practices that can curtail or limit erosion of vulnerable soils. Rainfall, and the surface runoff which may result from rainfall, produces four types of soil erosion, splash erosion, sheet erosion, rill erosion. Splash erosion is generally seen as the first and least severe stage in the erosion process. In splash erosion, the impact of a falling raindrop creates a crater in the soil. The distance these soil particles travel can be as much as 0.6 m vertically and 1.5 m horizontally on level ground. If the soil is saturated, or if the rate is greater than the rate at which water can infiltrate into the soil. If the runoff has sufficient flow energy, it will transport loosened soil particles down the slope, sheet erosion is the transport of loosened soil particles by overland flow. Rill erosion refers to the development of small, ephemeral concentrated flow paths which function as both sediment source and sediment delivery systems for erosion on hillslopes, generally, where water erosion rates on disturbed upland areas are greatest, rills are active. Flow depths in rills are typically of the order of a few centimetres or less and this means that rills exhibit hydraulic physics very different from water flowing through the deeper, wider channels of streams and rivers. Gully erosion occurs when water accumulates and rapidly flows in narrow channels during or immediately after heavy rains or melting snow

Mediterranean Sea
–
The sea is sometimes considered a part of the Atlantic Ocean, although it is usually identified as a separate body of water. The name Mediterranean is derived from the Latin mediterraneus, meaning inland or in the middle of land and it covers an approximate area of 2.5 million km2, but its connection to the Atlantic is only 14 km wide. The Strait of Gibraltar is a strait that connects the Atlantic Ocean to the Mediterranean Sea and separates Gibraltar. In oceanography, it is called the Eurafrican Mediterranean Sea or the European Mediterranean Sea to distinguish it from mediterranean seas elsewhere. The Mediterranean Sea has a depth of 1,500 m. The sea is bordered on the north by Europe, the east by Asia and it is located between latitudes 30° and 46° N and longitudes 6° W and 36° E. Its west-east length, from the Strait of Gibraltar to the Gulf of Iskenderun, the seas average north-south length, from Croatia’s southern shore to Libya, is approximately 800 km. The Mediterranean Sea, including the Sea of Marmara, has an area of approximately 2,510,000 square km. The sea was an important route for merchants and travelers of ancient times that allowed for trade, the history of the Mediterranean region is crucial to understanding the origins and development of many modern societies. In addition, the Gaza Strip and the British Overseas Territories of Gibraltar and Akrotiri, the term Mediterranean derives from the Latin word mediterraneus, meaning amid the earth or between land, as it is between the continents of Africa, Asia and Europe. The Ancient Greek name Mesogeios, is similarly from μέσο, between + γη, land, earth) and it can be compared with the Ancient Greek name Mesopotamia, meaning between rivers. The Mediterranean Sea has historically had several names, for example, the Carthaginians called it the Syrian Sea and latter Romans commonly called it Mare Nostrum, and occasionally Mare Internum. Another name was the Sea of the Philistines, from the people inhabiting a large portion of its shores near the Israelites, the sea is also called the Great Sea in the General Prologue by Geoffrey Chaucer. In Ottoman Turkish, it has also been called Bahr-i Sefid, in Modern Hebrew, it has been called HaYam HaTikhon, the Middle Sea, reflecting the Seas name in ancient Greek, Latin, and modern languages in both Europe and the Middle East. Similarly, in Modern Arabic, it is known as al-Baḥr al-Mutawassiṭ, in Turkish, it is known as Akdeniz, the White Sea since among Turks the white colour represents the west. Several ancient civilisations were located around the Mediterranean shores, and were influenced by their proximity to the sea. It provided routes for trade, colonisation, and war, as well as food for numerous communities throughout the ages, due to the shared climate, geology, and access to the sea, cultures centered on the Mediterranean tended to have some extent of intertwined culture and history. Two of the most notable Mediterranean civilisations in classical antiquity were the Greek city states, later, when Augustus founded the Roman Empire, the Romans referred to the Mediterranean as Mare Nostrum

Messinian salinity crisis
–
It ended with the Zanclean flood, when the Atlantic reclaimed the basin. Around 5.33 Ma with the Zanclean flood, even now, the Mediterranean is saltier than the North Atlantic because of its near isolation by the Strait of Gibraltar and its high rate of evaporation. If the Strait of Gibraltar closes again, which is likely to happen in the near geological future, after that, continued northward movement of Africa may obliterate the Mediterranean, see Mediterranean Ridge. In 1867, he named the period the Messinian, for the region of Messina, since then, salt-bearing and gypsum-bearing evaporite layers in many Mediterranean countries have been dated to that period. In 1961, seismic surveying of the Mediterranean basin revealed a geological feature some 100–200 m below the seafloor. This feature, dubbed the M reflector, closely followed the contours of the present seafloor, the origin of this layer was largely interpreted as related to salt deposition. However, different interpretations were proposed for the age of salt, earlier suggestions from Denizot in 1957 and Ruggieri in 1967 proposed that this layer was Late Miocene in age, and the same Ruggieri coined the term Messinian Salinity Crisis. New and high-quality seismic data on the M-reflector were acquired in the Mediterranean Basin in 1970 and these deposits were dated and interpreted for the first time as deep-basin products of the Messinian Salinity Crisis. These layers alternated with layers containing marine fossils, indicating a succession of drying and flooding periods, the massive presence of salt does not require a desiccation of the sea. For example, the Nile cut its bed down to several hundred feet below sea level at Aswan, in many places in the Mediterranean, fossilized cracks have been found where muddy sediment had dried and cracked in the sunlight and drought. This episode comprises the part of what is called the Messinian Epoch. The Epoch was characterised by stages of tectonic activity and sea level fluctuations, as well as erosional and depositional events. The Mediterranean-Atlantic strait closed tight time and time again, and the Mediterranean Sea, for the first time and then repeatedly, partially desiccated. The basin was finally isolated from the Atlantic Ocean for a longer period, during the initial, very dry stages, there was extensive erosion, creating several huge canyon systems. Later stages are marked by cyclic evaporite deposition into a large lake-sea basin, the basin has not desiccated since. The last refilling was at the Miocene/Pliocene boundary, when the Strait of Gibraltar broke wide open permanently. Upon closely examining the Hole 124 core, Kenneth J. Hsu found that, the fine sediments deposited on a quiet or deep bottom had perfectly even lamination. As the basin was drying up and the depth decreased

Upper Egypt
–
Upper Egypt is the strip of land on both sides of the Nile that extends between Nubia and downriver to Lower Egypt. Upper Egypt is between the Cataracts of the Nile above modern-day Aswan, downriver to the area between Dahshur and El-Ayait, which is south of modern-day Cairo, the northern part of Upper Egypt, between Sohag and El-Ayait, is also known as Middle Egypt. In Arabic, inhabitants of Upper Egypt are known as Saidis, in ancient Egypt, Upper Egypt was known as tꜣ šmꜣw, literally the Land of Reeds or the Sedgeland It was divided into twenty-two districts called nomes. The first nome was roughly where modern-day Aswan is and the twenty-second was at modern Atfih just to the south of Cairo, the main city of prehistoric Upper Egypt was Nekhen, whose patron deity was the vulture goddess Nekhbet. By about 3600 BC, Neolithic Egyptian societies along the Nile had based their culture on the raising of crops, shortly after 3600 BC, Egyptian society began to grow and increase in complexity. A new and distinctive pottery, which was related to the Levantine ceramics, extensive use of copper became common during this time. The Mesopotamian process of sun-drying adobe and architectural principles—including the use of the arch, concurrent with these cultural advances, a process of unification of the societies and towns of the upper Nile River, or Upper Egypt, occurred. At the same time the societies of the Nile Delta, or Lower Egypt also underwent a unification process, warfare between Upper and Lower Egypt occurred often. During his reign in Upper Egypt, King Narmer defeated his enemies on the Delta, for most of pharaonic Egypts history, Thebes was the administrative center of Upper Egypt. After its devastation by the Assyrians, its importance declined, under the Ptolemies, Ptolemais Hermiou took over the role of Upper Egypts capital city. Upper Egypt was represented by the tall White Crown Hedjet, and its symbols were the flowering lotus, in the 11th century, large numbers of pastoralists, known as Hilalians, fled Upper Egypt and moved westward into Libya and as far as Tunis. It is believed that degraded grazing conditions in Upper Egypt, associated with the beginning of the Medieval Warm Period, were the cause of the migration. In the 20th-century Egypt, the title Prince of the Said was used by the apparent to the Egyptian throne. Although the Kingdom of Egypt was abolished after the Egyptian revolution of 1952, media related to Upper Egypt at Wikimedia Commons

Nile Delta
–
The Nile Delta is the delta formed in Northern Egypt where the Nile River spreads out and drains into the Mediterranean Sea. It is one of the worlds largest river deltas—from Alexandria in the west to Port Said in the east, from north to south the delta is approximately 160 kilometres in length. The Delta begins slightly down-river from Cairo, from north to south, the delta is approximately 160 kilometres in length. From west-to-east, it covers some 240 kilometres of coastline, the delta is sometimes divided into sections, with the Nile dividing into two main distributaries, the Damietta and the Rosetta, flowing into the Mediterranean at port cities with the same name. In the past, the delta had several distributaries, but these have been lost due to flood control, one such defunct distributary is Wadi Tumilat. The Suez Canal runs to the east of the delta, entering the coastal Lake Manzala in the north-east of the delta, to the north-west are three other coastal lakes or lagoons, Lake Burullus, Lake Idku and Lake Maryut. The Nile is considered to be a delta, as it resembles a triangle or flower when seen from above. The outer edges of the delta are eroding, and some coastal lagoons have seen increasing salinity levels as their connection to the Mediterranean Sea increases, topsoil in the delta can be as much as 70 feet in depth. People have lived in the Delta region for thousands of years, the Delta River used to flood on an annual basis, but this ended with the construction of the Aswan Dam. The Rosetta Stone was found in the Nile Delta in 1799 in the city of Rosetta. The delta was a constituent of Lower Egypt. The Biblical Land of Goshen was located in an area on the west bank of the Pelusiac distributary. There are many sites in and around the Nile Delta. About 39 million people live in the Delta region, outside of major cities, population density in the delta averages 1,000 persons/km² or more. Alexandria is the largest city in the delta with a population of more than 4.5 million. Other large cities in the delta include Shubra al Khaymah, Port Said, El-Mahalla El-Kubra, El Mansura, Tanta, during autumn, parts of the Nile River are red with lotus flowers. The Lower Nile and the Upper Nile have plants that grow in abundance, the Upper Nile plant is the Egyptian lotus, and the Lower Nile plant is the Papyrus Sedge, although it is not nearly as plentiful as it once was, and is becoming quite rare. Several hundred thousand birds winter in the delta, including the world’s largest concentrations of little gulls

Kingdom of Kush
–
The Kingdom of Kush or Kush was an ancient Nubian kingdom situated on the confluences of the Blue Nile, White Nile and River Atbara in what is now Sudan and South Sudan. The Kushite era of rule in Nubia was established after the Bronze Age collapse and the disintegration of the New Kingdom of Egypt, during Classical antiquity, the Kushite imperial capital was at Meroe. In early Greek geography, the Meroitic kingdom was known as Aethiopia, by the 1st century AD, the Kushite capital had been captured by the Beja Dynasty, who tried to revive the empire. The Kushite kingdom with its capital at Meroe persisted until the 4th century AD, the Kushite capital was eventually captured and burnt to the ground by the Kingdom of Axum. It is also a term for the native population who initiated the kingdom of Kush. The term is also displayed in the names of Kushite persons, geographically, Kush referred to the region south of the first cataract in general. Kush also was the home of the rulers of the 25th dynasty, the name Kush, since at least the time of Josephus, has been connected with the biblical character Cush, in the Hebrew Bible, son of Ham. Ham had four sons named, Cush, Put, Canaan, according to the Bible, Nimrod, a son of Cush, was the founder and king of Babylon, Erech, Akkad and Calneh, in Shinar. The Bible also makes reference to someone named Cush who is a Benjamite, some modern scholars, such as Friedrich Delitzsch, have suggested that the biblical Cush might be linked to the Kassites of the Zagros Mountains. Mentuhotep II is recorded to have undertaken campaigns against Kush in the 29th and this is the earliest Egyptian reference to Kush, the Nubian region had gone by other names in the Old Kingdom. During the New Kingdom of Egypt, Nubia was an Egyptian colony, with the disintegration of the New Kingdom around 1070 BC, Kush became an independent kingdom centered at Napata in modern northern Sudan. The Kushites buried their monarchs along with all their courtiers in mass graves, archaeologists refer to these practices as the Pan-grave culture. This was given its due to the way in which the remains are buried. They would dig a pit and put stones around them in a circle, Kushites also built burial mounds and pyramids, and shared some of the same gods worshiped in Egypt, especially Ammon and Isis. With the worshiping of these gods the Kushites began to some of the names of the gods as their throne names. The Kush rulers were regarded as guardians of the religion and were responsible for maintaining the houses of the gods. Some scholars believe the economy in the Kingdom of Kush was a redistributive system, the state would collect taxes in the form of surplus produce and would redistribute to the people. Others believe that most of the society worked on the land and required nothing from the state, northern Kush seemed to be more productive and wealthier than the Southern area

Ancient Egypt
–
Ancient Egypt was a civilization of ancient Northeastern Africa, concentrated along the lower reaches of the Nile River in what is now the modern country of Egypt. It is one of six civilizations to arise independently, Egyptian civilization followed prehistoric Egypt and coalesced around 3150 BC with the political unification of Upper and Lower Egypt under the first pharaoh Narmer. In the aftermath of Alexander the Greats death, one of his generals, Ptolemy Soter and this Greek Ptolemaic Kingdom ruled Egypt until 30 BC, when, under Cleopatra, it fell to the Roman Empire and became a Roman province. The success of ancient Egyptian civilization came partly from its ability to adapt to the conditions of the Nile River valley for agriculture, the predictable flooding and controlled irrigation of the fertile valley produced surplus crops, which supported a more dense population, and social development and culture. Its art and architecture were widely copied, and its antiquities carried off to far corners of the world and its monumental ruins have inspired the imaginations of travelers and writers for centuries. The Nile has been the lifeline of its region for much of human history, nomadic modern human hunter-gatherers began living in the Nile valley through the end of the Middle Pleistocene some 120,000 years ago. By the late Paleolithic period, the climate of Northern Africa became increasingly hot and dry. In Predynastic and Early Dynastic times, the Egyptian climate was less arid than it is today. Large regions of Egypt were covered in treed savanna and traversed by herds of grazing ungulates, foliage and fauna were far more prolific in all environs and the Nile region supported large populations of waterfowl. Hunting would have been common for Egyptians, and this is also the period when many animals were first domesticated. The largest of these cultures in upper Egypt was the Badari, which probably originated in the Western Desert, it was known for its high quality ceramics, stone tools. The Badari was followed by the Amratian and Gerzeh cultures, which brought a number of technological improvements, as early as the Naqada I Period, predynastic Egyptians imported obsidian from Ethiopia, used to shape blades and other objects from flakes. In Naqada II times, early evidence exists of contact with the Near East, particularly Canaan, establishing a power center at Hierakonpolis, and later at Abydos, Naqada III leaders expanded their control of Egypt northwards along the Nile. They also traded with Nubia to the south, the oases of the desert to the west. Royal Nubian burials at Qustul produced artifacts bearing the oldest-known examples of Egyptian dynastic symbols, such as the crown of Egypt. They also developed a ceramic glaze known as faience, which was used well into the Roman Period to decorate cups, amulets, and figurines. During the last predynastic phase, the Naqada culture began using written symbols that eventually were developed into a system of hieroglyphs for writing the ancient Egyptian language. The Early Dynastic Period was approximately contemporary to the early Sumerian-Akkadian civilisation of Mesopotamia, the third-century BC Egyptian priest Manetho grouped the long line of pharaohs from Menes to his own time into 30 dynasties, a system still used today

Eratosthenes
–
Eratosthenes of Cyrene was a Greek mathematician, geographer, poet, astronomer, and music theorist. He was a man of learning, becoming the librarian at the Library of Alexandria. He invented the discipline of geography, including the terminology used today and he is best known for being the first person to calculate the circumference of the Earth, which he did by applying a measuring system using stadia, a standard unit of measure during that time period. He was also the first to calculate the tilt of the Earths axis, additionally, he may have accurately calculated the distance from the Earth to the Sun and invented the leap day. He created the first map of the world, incorporating parallels, Eratosthenes was the founder of scientific chronology, he endeavored to revise the dates of the chief literary and political events from the conquest of Troy. In number theory, he introduced the sieve of Eratosthenes, an efficient method of identifying prime numbers and he was a figure of influence in many fields. According to an entry in the Suda, his critics scorned him, nonetheless, his devotees nicknamed him Pentathlos after the Olympians who were well rounded competitors, for he had proven himself to be knowledgeable in every area of learning. Eratosthenes yearned to understand the complexities of the entire world, the son of Aglaos, Eratosthenes was born in 276 BC in Cyrene. Alexander the Great conquered Cyrene in 332 BC, and following his death in 323 BC, its rule was given to one of his generals, Ptolemy I Soter, the founder of the Ptolemaic Kingdom. Under Ptolemaic rule the economy prospered, based largely on the export of horses and silphium, Cyrene became a place of cultivation, where knowledge blossomed. Eratosthenes went to Athens to further his studies, there he was taught Stoicism by its founder, Zeno of Citium, in philosophical lectures on living a virtuous life. He then studied under Ariston of Chios, who led a more cynical school of philosophy and he also studied under the head of the Platonic Academy, who was Arcesilaus of Pitane. His interest in Plato led him to write his very first work at a level, Platonikos. Eratosthenes was a man of many perspectives and investigated the art of poetry under Callimachus and he was a talented and imaginative poet. He wrote poems, one in hexameters called Hermes, illustrating the life history. He wrote Chronographies, a text that scientifically depicted dates of importance and this work was highly esteemed for its accuracy. George Syncellus was later able to preserve from Chronographies a list of 38 kings of the Egyptian Thebes, Eratosthenes also wrote Olympic Victors, a chronology of the winners of the Olympic Games. It is not known when he wrote his works, but they highlighted his abilities and these works and his great poetic abilities led the pharaoh Ptolemy III Euergetes to seek to place him as a librarian at the Library of Alexandria in the year 245 BC

Winston Churchill
–
Sir Winston Leonard Spencer-Churchill KG OM CH TD PC DL FRS RA was a British statesman who was the Prime Minister of the United Kingdom from 1940 to 1945 and again from 1951 to 1955. Churchill was also an officer in the British Army, a historian. He won the Nobel Prize in Literature in 1953 for his overall, in 1963, he was the first of only eight people to be made an honorary citizen of the United States. Churchill was born into the family of the Dukes of Marlborough and his father, Lord Randolph Churchill, was a charismatic politician who served as Chancellor of the Exchequer, his mother, Jennie Jerome, was an American socialite. As a young officer, he saw action in British India, the Anglo–Sudan War. He gained fame as a war correspondent and wrote books about his campaigns, at the forefront of politics for fifty years, he held many political and cabinet positions. Before the First World War, he served as President of the Board of Trade, Home Secretary, during the war, he continued as First Lord of the Admiralty until the disastrous Gallipoli Campaign caused his departure from government. He then briefly resumed active service on the Western Front as commander of the 6th Battalion of the Royal Scots Fusiliers. He returned to government under Lloyd George as Minister of Munitions, Secretary of State for War, Secretary of State for Air, at the outbreak of the Second World War, he was again appointed First Lord of the Admiralty. Following the resignation of Neville Chamberlain on 10 May 1940, Churchill became Prime Minister and he led Britain as Prime Minister until victory over Nazi Germany had been secured. After the Conservative Party suffered a defeat in the 1945 general election. He publicly warned of an Iron Curtain of Soviet influence in Europe, after winning the 1951 election, Churchill again became Prime Minister. His second term was preoccupied by foreign affairs, including the Malayan Emergency, Mau Mau Uprising, Korean War, domestically his government laid great emphasis on house-building. Churchill suffered a stroke in 1953 and retired as Prime Minister in 1955. Upon his death aged ninety in 1965, Elizabeth II granted him the honour of a state funeral and his highly complex legacy continues to stimulate intense debate amongst writers and historians. Born into the family of the Dukes of Marlborough, a branch of the noble Spencer family, Winston Leonard Spencer-Churchill, like his father. His ancestor George Spencer had changed his surname to Spencer-Churchill in 1817 when he became Duke of Marlborough, to highlight his descent from John Churchill, Churchill was born on 30 November 1874, two months prematurely, in a bedroom in Blenheim Palace, Woodstock, Oxfordshire. From age two to six, he lived in Dublin, where his grandfather had been appointed Viceroy, Churchills brother, John Strange Spencer-Churchill, was born during this time in Ireland

The River War
–
The River War, An Historical Account of the Reconquest of the Soudan, by Winston Churchill, concerning his experiences as a British Army officer, during the Mahdist War in the Sudan. The River War was Churchills second published book after The Story of the Malakand Field Force, the River War was subsequently abridged to one volume in 1902. Aware that there was a war in Sudan, Churchill determined to be part of it and he was not alone in this, because in a time generally of peace, many British Army officers wanted experience of battle to further their careers. In Churchills case, he did not see his career as lying with the army and he first attempted to obtain a transfer from his regiment stationed in India to the 21st Lancers, which was the unit taking part in the war. This was granted by the War Office, but rejected by the commander of the British force in Sudan, Churchill next took leave to Britain, where he enlisted friends and family to lobby Kitchener to permit him to take part. This continued to be unsuccessful, even when the prime minister Lord Salisbury made an inquiry on his behalf, on 5 August he was in Luxor and on 24 August the regiment set out from Atbara to attack the Mahdist forces. As a direct result of Churchills writings, a rule was introduced prohibiting serving officers from also acting as war correspondents and they had met on a couple of previous occasions, and Churchill prevailed upon him also to read the manuscript. His suggestion was to reduce the degree of philosophising, that despite the accuracy of Churchills commentary it might bore the reader, while in the Sudan, Churchill participated in the Battle of Omdurman. Churchill comments at length on the mechanisation of war with use of the telegraph, railroad, the unabridged version contains many illustrations with drawings, photogravures, and coloured maps. The first edition was reviewed by The Times, which described it as containing material sufficient for two books and one bad one, with the bad one being the more interesting. About Islam he wrote, About the British attitude to war, About the modern machinery of war and its effectiveness against native tribesmen, a passage was highly critical of General Kitchener for ordering the desecration of the Mahdis tomb and carrying off his head as a trophy. The head was returned by the order of Lord Cromer, once he discovered what had happened, by contrast, American companies could supply locomotives immediately which were more effective and cheaper than some obtained from England.298 In 1902 Churchill had become a member of parliament. It was thought that the commentary about some of the people mentioned had better be excised in a revised edition, the book was thus edited down to one single volume, removing approximately one third of the total. Much of the content included passages where Churchill recounted his own experiences, as he had done in other works. This removal gave the book a somewhat different feel to these others. Other removals included discussions on the ethics of warfare, Churchills own opinions of events, the revised book was described as an authoritative history of the war.133 Abridgements were published numerous times over the twentieth century, with increasing excisions. A definitive new edition of the book, restoring it to the original two-volume text, in May 2013, Missouri State Representative Rick Stream composed and forwarded an e-mail to his House GOP colleagues. Sam Levin called the e-mail bizarre, with Rep. Stream alleging dangers of Islam, weston, a candidate in the May 2014 European Elections, was quoting from a section of Churchills book that described Islamic culture in unflattering terms

Anglo-Egyptian invasion of Sudan
–
The Anglo-Egyptian invasion of Sudan in 1896–1899 was a reconquest of territory lost by the Khedives of Egypt in 1884 and 1885 during the Mahdist War. The British had failed to organise a withdrawal of Egyptian forces from Sudan. The invasion of 1896-99 defeated and destroyed the Mahdist state and re-established Anglo-Egyptian rule, there was a considerable body of opinion in Britain in favour of retaking Sudan after 1885, largely to avenge Gordon. However Lord Cromer, the British Consul-General in Egypt, had been the architect of the British withdrawal after the Mahdist uprising and he remained sure that Egypt needed to recover its financial position before any invasion could be contemplated. Sudan is worth a good deal to Egypt he said, but it is not worth bankruptcy, as late as 15 November 1895 he had been assured by the British government that it had no plans to invade Sudan. The French government had in fact just dispatched Jean-Baptiste Marchand up the Congo with the aim of reaching Fashoda on the White Nile. This encouraged the British to attempt the full-scale defeat of the Mahdist state, Lord Salisbury then ordered the Sirdar, Brigadier Herbert Kitchener to make preparations for an advance up the Nile. As Governor-General of Suakin from 1886–88, Kitchener had held off the Mahdist forces under Osman Digna from the Red Sea coast, Kitchener took a methodical, unhurried approach to recovering Sudan. In the first year his objective was to recover Dongola, in the second, to construct a new railway from Wadi Halfa to Abu Hamad, in the third, to retake Khartoum. All the soldiers were Sudanese or Egyptian, with the exception of a few hundred men from the North Staffordshire Regiment and some Maxim gunners. The Egyptian army in the 1880s was consciously trying to distance itself from the times of Muhammad Ali, nevertheless on the eve of the 1896 invasion the manumission status and precise recruitment conditions of many Sudanese soldiers in the Egyptian army was unclear. Egyptian conscripts were required to serve six years in the army, whereas Sudanese soldiers enlisted before 1903 were signed up for life, Kitchener placed great importance on transport and communications. Reliance on river transport, and the vagaries of the Nile flooding, had reduced Garnet Wolseleys Nile Expedition to failure in 1885 and this required the building of new railways to support his invasion forces. The first phase of railway building followed the campaign up the Nile to the supply base at Akasha. This bypassed the second cataract of the Nile and thereby ensured that supplies could reach Dongola all year round, the railway extended as far as Akasha on 26 June and as far as Kosheh on 4 August 1896. A dockyard was constructed and three new gunboats, larger than the Egyptian river boats already deployed, were brought in sections by rail. Each carried one 12-pounder forward-firing gun, two 6-pounders midships and four Maxim guns, at the end of August 1896 storms washed away a 12-mile section of the railway as preparations were being made to advance on Dongola. Kitchener personally supervised 5,000 men who worked night and day to ensure it was rebuilt in a week, after Dongola was taken, this line was extended south to Kermah

Siege of Khartoum
–
The Battle of Khartoum, Siege of Khartoum or Fall of Khartoum was the conquest of Egyptian held Khartoum by the Mahdist forces led by Muhammad Ahmad. After a ten-month siege, when the Mahdists finally broke into the city, since the 1882 Anglo-Egyptian War, the British military presence had ensured that Egypt remained a de facto British protectorate. Egypt also controlled Sudan, and the administration of Sudan was considered a domestic Egyptian matter by the British government and it was left to the Khedives government to administer. As a result, the suppression of the Mahdist revolt was left to the Egyptian army, the Mahdis forces captured huge amounts of equipment and overran large parts of Sudan, including Darfur and Kordofan. The Mahdist forces backed their self-proclaimed Mahdi, Muhammad Ahmad and he claimed to be the redeemer of the Islamic nation and enjoyed the support of many in Sudan who desired independence from their Egyptian rulers. The rebellion brought Sudan to the attention of the British government, prime Minister William Gladstone and War Secretary Lord Hartington did not wish to become involved in Sudan and persuaded the Egyptian government to evacuate all their garrisons in Sudan. General Charles George Gordon, a figure in Great Britain. His fears were based on the Mahdis claim to dominion over the entire Islamic world and on the fragility of the Egyptian army, which had suffered several defeats at the hands of the Sudanese. Gordon favoured a policy in Sudan, in agreement with noted imperialists such as Sir Samuel Baker and Sir Garnet Wolseley. On his way to Khartoum with his assistant, Colonel Stewart, here he committed a cardinal mistake by revealing that the Egyptian government wished to withdraw from Sudan. The tribesmen became worried by news, and their loyalty wavered. Gordon arrived at Khartoum on 18 February 1884, but instead of organising the evacuation of the garrisons and his first decisions were to reduce the injustices caused by the Egyptian colonial administration, arbitrary imprisonments were cancelled, torture instruments were destroyed, and taxes were remitted. To enlist the support of the population, Gordon legalised slavery and this decision was popular in Khartoum, but caused controversy in Britain. Gordon was determined to smash up the Mahdi and he requested that a regiment of Turkish soldiers be sent to Khartoum as Egypt was still nominally a province of the Ottoman Empire. When this was refused, Gordon asked for a unit of Indian Muslim troops, all these proposals were rejected by the Gladstone cabinet, since Britain was still intent on evacuation and refused absolutely to be pressured into military intervention in Sudan. Gordon began to resent the governments policy, and his telegrams to Cairo became more acrimonious, on 8 April he wrote, I leave you with the indelible disgrace of abandoning the garrisons and added that such a course would be the climax of meanness. Knowing that the Mahdists were closing in, Gordon finally ordered the strengthening of the fortifications around Khartoum, the city was protected to the north by the Blue Nile and to the west by the White Nile. In the southern part of the town, which faced the open desert, he prepared a system of trenches, makeshift Fougasse-type land mines

International Standard Serial Number
–
An International Standard Serial Number is an eight-digit serial number used to uniquely identify a serial publication. The ISSN is especially helpful in distinguishing between serials with the same title, ISSN are used in ordering, cataloging, interlibrary loans, and other practices in connection with serial literature. The ISSN system was first drafted as an International Organization for Standardization international standard in 1971, ISO subcommittee TC 46/SC9 is responsible for maintaining the standard. When a serial with the content is published in more than one media type. For example, many serials are published both in print and electronic media, the ISSN system refers to these types as print ISSN and electronic ISSN, respectively. The format of the ISSN is an eight digit code, divided by a hyphen into two four-digit numbers, as an integer number, it can be represented by the first seven digits. The last code digit, which may be 0-9 or an X, is a check digit. Formally, the form of the ISSN code can be expressed as follows, NNNN-NNNC where N is in the set, a digit character. The ISSN of the journal Hearing Research, for example, is 0378-5955, where the final 5 is the check digit, for calculations, an upper case X in the check digit position indicates a check digit of 10. To confirm the check digit, calculate the sum of all eight digits of the ISSN multiplied by its position in the number, the modulus 11 of the sum must be 0. There is an online ISSN checker that can validate an ISSN, ISSN codes are assigned by a network of ISSN National Centres, usually located at national libraries and coordinated by the ISSN International Centre based in Paris. The International Centre is an organization created in 1974 through an agreement between UNESCO and the French government. The International Centre maintains a database of all ISSNs assigned worldwide, at the end of 2016, the ISSN Register contained records for 1,943,572 items. ISSN and ISBN codes are similar in concept, where ISBNs are assigned to individual books, an ISBN might be assigned for particular issues of a serial, in addition to the ISSN code for the serial as a whole. An ISSN, unlike the ISBN code, is an identifier associated with a serial title. For this reason a new ISSN is assigned to a serial each time it undergoes a major title change, separate ISSNs are needed for serials in different media. Thus, the print and electronic versions of a serial need separate ISSNs. Also, a CD-ROM version and a web version of a serial require different ISSNs since two different media are involved, however, the same ISSN can be used for different file formats of the same online serial

International Standard Book Number
–
The International Standard Book Number is a unique numeric commercial book identifier. An ISBN is assigned to each edition and variation of a book, for example, an e-book, a paperback and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, the method of assigning an ISBN is nation-based and varies from country to country, often depending on how large the publishing industry is within a country. The initial ISBN configuration of recognition was generated in 1967 based upon the 9-digit Standard Book Numbering created in 1966, the 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108. Occasionally, a book may appear without a printed ISBN if it is printed privately or the author does not follow the usual ISBN procedure, however, this can be rectified later. Another identifier, the International Standard Serial Number, identifies periodical publications such as magazines, the ISBN configuration of recognition was generated in 1967 in the United Kingdom by David Whitaker and in 1968 in the US by Emery Koltay. The 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108, the United Kingdom continued to use the 9-digit SBN code until 1974. The ISO on-line facility only refers back to 1978, an SBN may be converted to an ISBN by prefixing the digit 0. For example, the edition of Mr. J. G. Reeder Returns, published by Hodder in 1965, has SBN340013818 -340 indicating the publisher,01381 their serial number. This can be converted to ISBN 0-340-01381-8, the check digit does not need to be re-calculated, since 1 January 2007, ISBNs have contained 13 digits, a format that is compatible with Bookland European Article Number EAN-13s. An ISBN is assigned to each edition and variation of a book, for example, an ebook, a paperback, and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, a 13-digit ISBN can be separated into its parts, and when this is done it is customary to separate the parts with hyphens or spaces. Separating the parts of a 10-digit ISBN is also done with either hyphens or spaces, figuring out how to correctly separate a given ISBN number is complicated, because most of the parts do not use a fixed number of digits. ISBN issuance is country-specific, in that ISBNs are issued by the ISBN registration agency that is responsible for country or territory regardless of the publication language. Some ISBN registration agencies are based in national libraries or within ministries of culture, in other cases, the ISBN registration service is provided by organisations such as bibliographic data providers that are not government funded. In Canada, ISBNs are issued at no cost with the purpose of encouraging Canadian culture. In the United Kingdom, United States, and some countries, where the service is provided by non-government-funded organisations. Australia, ISBNs are issued by the library services agency Thorpe-Bowker

Strabo
–
Strabo was a Greek geographer, philosopher, and historian who lived in Asia Minor during the transitional period of the Roman Republic into the Roman Empire. Strabo was born to an affluent family from Amaseia in Pontus, Strabos life was characterized by extensive travels. He journeyed to Egypt and Kush, as far west as coastal Tuscany and as far south as Ethiopia in addition to his travels in Asia Minor and the time he spent in Rome. Travel throughout the Mediterranean and Near East, especially for scholarly purposes, was popular during this era and was facilitated by the relative peace enjoyed throughout the reign of Augustus. He moved to Rome in 44 BC, and stayed there, studying and writing, in 29 BC, on his way to Corinth, he visited the island of Gyaros in the Aegean Sea. Around 25 BC, he sailed up the Nile until reaching Philae and it is not known precisely when Strabos Geography was written, though comments within the work itself place the finished version within the reign of Emperor Tiberius. Some place its first drafts around 7 BC, others around 17 or 18 AD, the latest passage to which a date can be assigned is his reference to the death in AD23 of Juba II, king of Maurousia, who is said to have died just recently. He probably worked on the Geography for many years and revised it steadily, on the presumption that recently means within a year, Strabo stopped writing that year or the next, when he died. The first of Strabos major works, Historical Sketches, written while he was in Rome, is completely lost. Strabo studied under several prominent teachers of various specialties throughout his life at different stops along his Mediterranean travels. His first chapter of education took place in Nysa under the master of rhetoric Aristodemus, Strabo was an admirer of Homers poetry, perhaps a consequence of his time spent in Nysa with Aristodemus. At around the age of 21, Strabo moved to Rome, where he studied philosophy with the Peripatetic Xenarchus, despite Xenarchuss Aristotelian leanings, Strabo later gives evidence to have formed his own Stoic inclinations. In Rome, he learned grammar under the rich and famous scholar Tyrannion of Amisus. Although Tyrannion was also a Peripatetic, he was more relevantly a respected authority on geography, the final noteworthy mentor to Strabo was Athenodorus Cananites, a philosopher who had spent his life since 44 BC in Rome forging relationships with the Roman elite. Athenodorus endowed to Strabo three important items, his philosophy, his knowledge, and his contacts, moreover, from his own first-hand experience, Athenodorus provided Strabo with information about regions of the empire which he would not otherwise have known. Strabo is most notable for his work Geographica, which presented a history of people. Although the Geographica was rarely utilized in its antiquity, a multitude of copies survived throughout the Byzantine Empire. It first appeared in Western Europe in Rome as a Latin translation issued around 1469, the first Greek edition was published in 1516 in Venice
