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 north of the capital Khartoum. Its dimensions make it the largest contemporary hydropower project in Africa. 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 downstream from the construction site at Hamdab. The main purpose for building the dam was the generation of electricity. Technical details The dam has a length of about and a crest height of up to . It consists of concrete-faced rockfill dams on each river bank (the right bank dam is the largest part of the project, 4.3 km long and 53m high; the left bank is 1590 metres long and 50 metres high), an -long -high earth-core rockfill dam (the 'main dam') in the left river channel, and a live water section in the right river channel (sl ...

Omdurman
Omdurman (standard ar, أم درمان ''Umm Durmān'') is a city in Sudan. It is the most populated city in the country, and thus also in the State of Khartoum. Omdurman lies on the west bank of the River Nile, opposite and northwest of the capital city of Khartoum. Etymology The name Omdurman (''Umm Durmān'') literally translates as "Mother of Durmān", but who she was or might have been is not known. History After the siege of Khartoum, followed by the building there of the tomb of the Mahdi after his death from typhus, the city grew rapidly. However, in the Battle of Omdurman in 1898 (which actually took place in the nearby village of Kerreri), Lord Kitchener decisively defeated the Mahdist forces. The following year British forces defeated Abdallahi ibn Muhammad, the Khalifa, as the Battle of Umm Diwaykarat; ensuring British control over the Sudan. In September 1898, the British army of twenty thousand well drilled men equipped with the latest arms, Maxim guns a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hydroelectricity
Hydroelectricity, or hydroelectric power, is Electricity generation, electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other Renewable energy, renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of Low-carbon power, low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Gaafar Nimeiry
Jaafar Muhammad an-Nimeiry (otherwise spelled in English as Jaafar Nimeiry, Gaafar Nimeiry or Ja'far Muhammad Numayri; ar, جعفر محمد النميري; 26 April 192830 May 2009) was a Sudanese politician who served as the president of Sudan from 1969 to 1985. A military officer, he came to power after a military coup in 1969. Establishing a one-party state, with his Sudanese Socialist Union as the sole legal political entity in the country, Nimeiry pursued socialist and Pan-Arabist policies and close collaboration with Gamal Abdel Nasser of Egypt and Muammar Gaddafi of Libya. In 1971 Nimeiry survived a pro-Soviet coup attempt, after which he forged an alliance with Mao Zedong of China, and, eventually, with the United States as well. In 1972 he signed the Addis Ababa Agreement, ending the First Sudanese Civil War. In his last years in power he also adopted aspects of Islamism, and in 1983 he imposed Sharia law throughout the country, precipitating the Second Sudanese ...

Lake Nasser
Lake Nasser ( ar, بحيرة ناصر ', ) 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 Sudan's land near the area of Lake Nasser was mostly flooded by the lake. Strictly speaking, "Lake Nasser" refers only to the much larger portion of the lake that is in Egyptian territory (83% of the total), with the Sudanese preferring to call their smaller body of water Lake Nubia ( arz, بحيرة النوبة ', ). __TOC__ Description The lake is some long and across at its widest point, which is near the Tropic of Cancer. It covers a total surface area of and has a storage capacity of some 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. Th ...

Aswan Dam
The Aswan Dam, or more specifically since the 1960s, the Aswan High Dam, is one of the world's largest embankment dams, which was built across the Nile in Aswan, Egypt, between 1960 and 1970. Its significance largely eclipsed the previous Aswan Low Dam initially completed in 1902 downstream. Based on the success of the Low Dam, then at its maximum utilization, construction of the High Dam became a key objective of the government following the Egyptian Revolution of 1952; with its ability to better control flooding, provide increased water storage for irrigation and generate hydroelectricity, the dam was seen as pivotal to Egypt's planned industrialization. Like the earlier implementation, the High Dam has had a significant effect on the economy and culture of Egypt. Before the High Dam was built, even with the old dam in place, the annual flooding of the Nile during late summer had continued to pass largely unimpeded down the valley from its East African drainage basin. These flo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Egypt
Egypt ( ar, مصر , ), officially the Arab Republic of Egypt, is a transcontinental country spanning the northeast corner of Africa and southwest corner of Asia via a land bridge formed by the Sinai Peninsula. It is bordered by the Mediterranean Sea to the north, the Gaza Strip of Palestine and Israel to the northeast, the Red Sea to the east, Sudan to the south, and Libya to the west. The Gulf of Aqaba in the northeast separates Egypt from Jordan and Saudi Arabia. Cairo is the capital and largest city of Egypt, while Alexandria, the second-largest city, is an important industrial and tourist hub at the Mediterranean coast. At approximately 100 million inhabitants, Egypt is the 14th-most populated country in the world. Egypt has one of the longest histories of any country, tracing its heritage along the Nile Delta back to the 6th–4th millennia BCE. Considered a cradle of civilisation, Ancient Egypt saw some of the earliest developments of writing, agriculture, ur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Countries By Date Of Nationhood
Below is a list of sovereign states with the dates of their formation (date of their independence or of their constitution), sorted by continent. This list includes the 195 states which are currently full member states or observer states of the United Nations. This does not include extinct states, but does include several states with limited recognition. For proposed states or various indigenous nations which consider themselves still under occupation, see list of active autonomist and secessionist movements. Nation-building is a long evolutionary process, and in most cases the date of a country's "formation" cannot be objectively determined; e.g., the fact that England and France were sovereign kingdoms on equal footing in the medieval period does not prejudice the fact that England is not now a sovereign state (having passed sovereignty to Great Britain in 1707), while France is a Republic founded in 1792 (though the term ''France'' generally refers to the current French F ...

Independence
Independence is a condition of a person, nation, country, or state in which residents and population, or some portion thereof, exercise self-government, and usually sovereignty, over its territory. The opposite of independence is the status of a dependent territory. The commemoration of the independence day of a country or nation celebrates when a country is free from all forms of foreign colonialism; free to build a country or nation without any interference from other nations. Definition of independence Whether the attainment of independence is different from revolution has long been contested, and has often been debated over the question of violence as legitimate means to achieving sovereignty. In general, revolutions aim only to redistribute power with or without an element of emancipation,such as in democratization ''within'' a state, which as such may remain unaltered. For example, the Mexican Revolution (1910) chiefly refers to a multi-factional conflict that e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cotton
Cotton is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus ''Gossypium'' in the mallow family Malvaceae. The fiber is almost pure cellulose, and can contain minor percentages of waxes, fats, pectins, and water. Under natural conditions, the cotton bolls will increase the dispersal of the seeds. The plant is a shrub native to tropical and subtropical regions around the world, including the Americas, Africa, Egypt and India. The greatest diversity of wild cotton species is found in Mexico, followed by Australia and Africa. Cotton was independently domesticated in the Old and New Worlds. The fiber is most often spun into yarn or thread and used to make a soft, breathable, and durable textile. The use of cotton for fabric is known to date to prehistoric times; fragments of cotton fabric dated to the fifth millennium BC have been found in the Indus Valley civilization, as well as fabric remnants dated back ...

Anglo-Egyptian Sudan
Anglo-Egyptian Sudan ( ar, السودان الإنجليزي المصري ') was a condominium of the United Kingdom and Egypt in the Sudans region of northern Africa between 1899 and 1956, corresponding mostly to the territory of present-day Sudan and South Sudan. Legally, sovereignty and administration were shared between both Egypt and the United Kingdom, but in practice the structure of the condominium ensured effective British control over Sudan, with Egypt having limited, local power influence in reality. In the mean time, Egypt itself fell under increasing British influence. Following the Egyptian Revolution of 1952, Egypt pushed for an end to the condominium, and the independence of Sudan. By agreement between Egypt and the United Kingdom in 1953, Sudan was granted independence as the Republic of the Sudan on 1 January 1956. In 2011, the south of Sudan itself became independent as the Republic of South Sudan. In the 19th century, whilst nominally a vassal state of the ...
