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 African drainage 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.
Egyptian President Nasser and Soviet leader Khrushchevat the ceremony to divert the Nile during the construction of the Aswan High Dam on May 14, 1964. At this occasion Khrushchev called it "the eighth wonder of the world"
Construction and filling, 1960–1976
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.
