A Barragem de Assuão faz hoje 54 anos
A Represa Alta de Assuão ou Assuão Alta é uma barragem egípcia localizada no rio Nilo, próxima da cidade de Assuão.
Construção
A mais antiga tentativa registada de construir uma represa próxima de Assuão remonta ao século XI, quando o polímata e engenheiro Alhazen foi convocado ao Egito pelo califa fatímida Aláqueme Biamir Alá,
para controlar a inundação do Nilo. Para concluir esta tarefa, seria
necessário construir uma represa em Assuão. O seu trabalho de campo o
convenceu de que o projeto era impraticável.
Os britânicos começaram a planear a construção da primeira represa em 1899 e terminaram em 1902.
Ela possuía 54 metros de altura e 1.900 metros de extensão, logo este
tamanho se mostrou inadequado por isso a barragem foi ampliada em duas
novas etapas, a primeira entre 1907 e 1912 e depois entre 1929 e 1933.
Em 1946, a represa quase se rompeu, e percebeu-se que seria necessário
construir uma segunda represa. Ela seria construída a aproximadamente 6 quilómetros acima da atual. Os planos para a construção começaram a ser realizados em 1952, logo após a revolução de Nasser, e os Estados Unidos e o Reino Unido ajudariam a financiar a construção com um empréstimo de USD $ 270 milhões de dólares. Em julho de 1956, no entanto, o acordo foi cancelado. Para concluir a construção da represa, Nasser nacionalizou o canal de Suez, pretendendo utilizar a renda proveniente para o intento. Isto fez com que Reino Unido, França e Israel atacassem o Egito, ocupando o Canal de Suez, começando a Guerra de Suez. As Nações Unidas, os Estados Unidos e a URSS forçaram os invasores a devolver o canal a Nasser. Em 1958,
a URSS ajudou a construção da represa, com um terço dos recursos
financeiros necessários, máquinas e técnicos especializados.
(...)
A construção começou em 1960, com o primeiro estágio concluído em 1964, tendo sido concluída em 21 de julho de 1970.

The Aswan Dam is an embankment dam situated across the Nile River in Aswan, Egypt.
Since the 1960s, the name commonly refers to the High Dam. Construction
of the High Dam became a key objective of the Egyptian Government
following the Egyptian Revolution of 1952, as the ability to control floods, provide water for irrigation, and generatehydroelectricity were seen as pivotal to Egypt's industrialization. The High Dam was constructed between 1960 and 1970, and has had a significant impact on the economy and culture of Egypt.
Before the dams were built, the Nile River flooded every year during late summer, when water flowed down the valley from its East Africandrainage basin. These floods brought high water and natural nutrients and minerals that annually enriched the fertile soil along the floodplain and delta; this had made the Nile valley ideal for farming since ancient times. Because floods vary, in high-water years the whole crop might be wiped out, while in low-water years widespread drought and famine occasionally occurred. As Egypt's population grew and conditions changed, both a desire and ability developed to control the floods, and thus both protect and support farmland and the economically important cotton crop. With the reservoir storage provided by the Aswan dams, the floods could be lessened and the water stored for later release.

The Soviets also provided technicians and heavy machinery. The enormous rock and clay dam was designed by the SovietHydroproject Institute along with some Egyptian engineers. Twenty-five thousand Egyptian engineers and workers contributed to the construction of the dams.
On the Egyptian side, the project was led by Osman Ahmed Osman's Arab Contractors. The relatively young Osman underbid his only competitor by one-half.
