The Aswan Dam, or 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. When it was completed, it was the tallest earthen dam in the world, surpassing the Chatuge Dam in the United States. [ 2 ]
Environmentally, the Aswan Dam has contributed to numerous issues for Egyptians. The expansion of desert areas since the Aswan High Dam's construction in 1970 has increased in soil salinity which allowed for waterborne diseases to emerge. In 1994, 28% of Egypt's soils were damaged by significant levels of salinity. [3]
After the Aswan Dam was constructed in Egypt it protected Egypt from the droughts in 1972–1973 and 1983–1987 that devastated East and West Africa. The dam allowed Egypt to reclaim about 840,000 hectares in the Nile Delta and along the Nile Valley, increasing the country's irrigated area by a third. The increase was brought about both by ...
However, they were still not able to retain sufficient water to cope with the driest summers, despite the Aswan Low Dam being raised twice, in 1907–1912 and in 1929–1933. During the 1920s, the Sennar Dam was constructed on the Blue Nile as a reservoir in order to supply water to the huge Gezira Scheme on a regular basis. It was the first ...
The Nile Delta flooded savanna, ecoregion (WWF ID: PA0904) covers both the Nile Delta proper, where the Nile River enters the Mediterranean Sea, as well as the river floodplains of the Nile 1,100 kilometres (680 mi) up-river to the Aswan Dam. Since the Aswan Dam was completed in the 1970s, the Nile on this stretch has not been subject to annual ...
Lake Nasser behind the Aswan High Dam. The history of modern water management in Egypt begins with the construction of the Old Aswan Dam in 1902 and barrages on the Nile in the 19th and early 20th century. The Old Aswan Dam partially stored the waters of the Nile to allow the growing of multiple crops per year in the Nile Delta, while the ...
Philae flooded by the Aswan Low Dam in 1906. In 1902, the Aswan Low Dam was completed on the Nile River by the British. This threatened to submerge many ancient landmarks, including the temple complex of Philae. The height of the dam was raised twice, from 1907 to 1912 and from 1929 to 1934, and the island of Philae was nearly
Until 1974, the ruins of temples and an ancient Egyptian city were located here. They were damaged by several decades of seasonal submergence of the lake holding back the old Aswan Dam. [2] [3] With the commissioning of the Aswan High Dam in 1970, there was a threat of permanent flooding of the area. [4]
