Roseires Dam
The Roseires Dam ( ar, خزان الروصيرص) is a dam on the Blue Nile at Ad Damazin, just upstream of the town of Er Roseires, in Sudan. It consists of a concrete buttress dam 1 km wide with a maximum height of 68 m, and an earth dam An embankment dam is a large artificial dam. It is typically created by the placement and compaction of a complex semi-plastic mound of various compositions of soil or rock. It has a semi-pervious waterproof natural covering for its surface and ... on either side. The earth dam on the eastern bank is 4 km long, and that on the western bank is 8.5 km long. The reservoir has a surface area of about 290 km2. The dam was completed in 1966, initially for irrigation purposes. A power generation plant, with a maximum capacity of 280 megawatts, was added in 1971. A heightening (and lengthening) project was completed in 2013 and the dam is now 25 km long.

Ad Damazin
Ad-Damazin ( ar, الدمازين, Ad-Damāzīn) is the capital city of Blue Nile, Sudan. It is the location of the Roseires Dam and power generation plant. Ad-Damazin is served by a terminal station of a branch line of the national railway network. However, the train service to Ad-Damazin has been discontinued many years ago. Instead the town can be reached from Khartoum via a decent tarmac road and by plane. However, Damazin Airport is mainly served by UNMIS or government flights. Ad-Damazin is a city filled with many dialects, but the majority of the population speaks Sudanese Arabic, which is an accent of the original Arabic language. The city lies west of the Nile river and northwest of the Roseires reservoir. Blue Nile University (Jameat Al Neel Alazraq) is a public university located in Ad-Damazin, established in 1995. Climate Like other parts of the Sahel, Ad-Damazin has a hot semi-arid climate (Köppen climate classification ''BSh''), with a wet season and a dry seaso ...

Sudan
Sudan ( or ; ar, السودان, as-Sūdān, officially the Republic of the Sudan ( ar, جمهورية السودان, link=no, Jumhūriyyat as-Sūdān), is a country in Northeast Africa. It shares borders with the Central African Republic to the southwest, Chad to the west, Egypt to the north, Eritrea to the northeast, Ethiopia to the southeast, Libya to the northwest, South Sudan to the south and the Red Sea. It has a population of 45.70 million people as of 2022 and occupies 1,886,068 square kilometres (728,215 square miles), making it Africa's List of African countries by area, third-largest country by area, and the third-largest by area in the Arab League. It was the largest country by area in Africa and the Arab League until the 2011 South Sudanese independence referendum, secession of South Sudan in 2011, since which both titles have been held by Algeria.

Blue Nile
The Blue Nile (; ) is a river originating at Lake Tana in Ethiopia. It travels for approximately through Ethiopia and Sudan. Along with the White Nile, it is one of the two major tributaries of the Nile and supplies about 85.6% of the water to the Nile during the rainy season. Course The distance of the river from its source to its confluence has been variously reported as being between and . This uncertainty might result from the fact that the river flows through a series of virtually impenetrable gorges cut in the Ethiopian Highlands to a depth of some . According to materials published by the Central Statistical Agency, the Blue Nile has a total length of , of which are inside Ethiopia. In Ethiopia The Blue Nile originates at Lake Tana in Ethiopia (where it is called the Abay River). The river flows generally south before entering a canyon about long, about from Lake Tana, which is a tremendous obstacle for travel and communication between north and south Ethiop ...

Er Roseires
Er Roseires ( ar, الروصيرص, al-Rūṣayriṣ) is a town in eastern Sudan 60 km from the border with Ethiopia. Lord Prudhoe mentions this town in the 1829 diary he kept while travelling in the Sennar. At the time it was the residence of one Sheikh Suliman, ruler of the lower reach of the Blue Nile (Baḥr al-Azraq), for which he paid 1500 ounces of gold to the Egyptians out of his revenues.Lord Prudhoe"Extracts from Private Memoranda Kept by Lord Prudhoe on a Journey from Cairo to Sennar,in 1829, Describing the Peninsula of Sennar", ''Journal of the Royal Geographical Society'' 5 (1835), p. 52 The Roseires Dam The Roseires Dam ( ar, خزان الروصيرص) is a dam on the Blue Nile at Ad Damazin, just upstream of the town of Er Roseires, in Sudan.

Buttress Dam
A buttress dam or hollow dam is a dam with a solid, water-tight upstream side that is supported at intervals on the downstream side by a series of buttresses or supports. The dam wall may be straight or curved. Most buttress dams are made of reinforced concrete and are heavy, pushing the dam into the ground. Water pushes against the dam, but the buttresses are inflexible and prevent the dam from falling over. Buttress or hollow gravity dams were originally built to retain water for irrigation or mining in areas of scarce or expensive resources but cheap labour. A buttress dam is a good choice in wide valleys where solid rock is rare. As designs have become more sophisticated, the virtues and weaknesses of buttress dams have become apparent. The Romans were the first to use buttresses to increase the stability of a dam wall. Buttress dams of slab concrete construction became popular in the United States in the early 20th Century with the patented process of Norwegian-American civil ...

Earth Dam
An embankment dam is a large artificial dam. It is typically created by the placement and compaction of a complex semi-plastic mound of various compositions of soil or rock. It has a semi-pervious waterproof natural covering for its surface and a dense, impervious core. This makes the dam impervious to surface or seepage erosion. Such a dam is composed of fragmented independent material particles. The friction and interaction of particles binds the particles together into a stable mass rather than by the use of a cementing substance. Types Embankment dams come in two types: the earth-filled dam (also called an earthen dam or terrain dam) made of compacted earth, and the rock-filled dam. A cross-section of an embankment dam shows a shape like a bank, or hill. Most have a central section or core composed of an impermeable material to stop water from seeping through the dam. The core can be of clay, concrete, or asphalt concrete. This type of dam is a good choice for sites with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dams In Sudan
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
