42 ha or about 1 acre. * Data from the Egyptian Water Use Management Project (EWUP)[19] The salt concentration of the water in the Aswan reservoir is about 0. 25 kilograms per cubic metre (0. 42 lb/cu yd), a very low salinity level. At an annual inflow of 55 cubic kilometres (45, 000, 000 acre⋅ft), the annual salt influx reaches 14 million tons. The average salt concentration of the drainage water evacuated into the sea and the coastal lakes is 2. 7 kilograms per cubic metre (4. 6 lb/cu yd). [20] At an annual discharge of 10 cubic kilometres (2. 4 cu mi) (not counting the 2 kilograms per cubic metre [3.
The Temple of Ptah at Gerf Hussein had its free-standing section reconstructed at New Kalabsha, alongside the Temple of Kalabsha, Beit el-Wali, and the Kiosk of Qertassi. The remaining archaeological sites, including the Buhen fort and the cemetery of Fadrus have been flooded by Lake Nasser. Loss of sediments[edit] Lake Nasser behind the Aswan dam displaced more than 100, 000 people and traps significant amounts of sediment. Before the construction of the High Dam, the Nile deposited sediments of various particle size – consisting of fine sand, silt and clay – on fields in Upper Egypt through its annual flood, contributing to soil fertility. However, the nutrient value of the sediment has often been overestimated.
Soil salinity also increased because the distance between the surface and the groundwater table was small enough (1–2 m depending on soil conditions and temperature) to allow water to be pulled up by evaporation so that the relatively small concentrations of salt in the groundwater accumulated on the soil surface over the years. Since most of the farmland did not have proper subsurface drainage to lower the groundwater table, salinization gradually affected crop yields. [28] Drainage through sub-surface drains and drainage channels is essential to prevent a deterioration of crop yields from soil salinization and waterlogging. By 2003, more than 2 million hectares have been equipped with a subsurface drainage system at a cost from 1973 to 2002 of about $3.
This was a consequence of the conversion of the Delta to perennial irrigation to grow long staple cotton by the British. This has changed. Large-scale treatment programmes in the 1990s using single-dose oral medication contributed greatly to reducing the prevalence and severity of S. mansoni in the Delta. Other effects[edit] Sediment deposited in the reservoir is lowering the water storage capacity of Lake Nasser. The reservoir storage capacity is 162 km3, including 31 km3 dead storage at the bottom of the lake below 147 m (482 ft) above sea level, 90 km3 live storage, and 41 km3 of storage for high flood waters above 175 m (574 ft) above sea level.

By the 1950s only a small proportion of Upper Egypt had not been converted from basin (low transmission) to perennial (high transmission) irrigation. Expansion of perennial irrigation systems in Egypt did not depend on the high dam. In fact, within 15 years of the high dam closure there was solid evidence that bilharzia was declining in Upper Egypt. haematobium has since disappeared altogether. [41] Suggested reasons for this include improvements in irrigation practice. In the Nile Delta, schistosomiasis had been highly endemic, with prevalence in the villages 50% or higher for almost a century before.
The annual sediment load of the Nile is about 134 million tons. This means that the dead storage volume would be filled up after 300–500 years if the sediment accumulated at the same rate throughout the area of the lake. Obviously sediment accumulates much faster at the upper reaches of the lake, where sedimentation has already affected the live storage zone. [36] Before the construction of the High Dam, the 50, 000 km (31, 000 mi) of irrigation and drainage canals in Egypt had to be dredged regularly to remove sediments. After construction of the dam, aquatic weeds grew much faster in the clearer water, helped by fertilizer residues. The total length of the infested waterways was about 27, 000 km (17, 000 mi) in the mid-1990s.
Although the Low Dam was almost overtopped in 1946, the government of King Farouk showed no interest in Daninos's plans. Instead the Nile Valley Plan by the British hydrologist Harold Edwin Hurst was favored, which proposed to store water in Sudan and Ethiopia, where evaporation is much lower. The Egyptian position changed completely after the overthrow of the monarchy, led by the Free Officers Movement including Gamal Abdel Nasser. The Free Officers were convinced that the Nile Waters had to be stored in Egypt for political reasons, and within two months, the plan of Daninos was accepted. [7] Initially, both the United States and the USSR were interested in helping development of the dam. Complications ensued due to their rivalry during the Cold War, as well as growing intra-Arab tensions. In 1955, Nasser was claiming to be the leader of Arab nationalism, in opposition to the traditional monarchies, especially the Hashemite Kingdom of Iraq following its signing of the 1955 Baghdad Pact.
Most of the 32 km3 of freshwater, or almost 40 percent of the average flow of the Nile that were previously lost to the sea every year could be put to beneficial use. While about 10 km3 of the water saved is lost due to evaporation in Lake Nasser, the amount of water available for irrigation still increased by 22 km3. [27] Other estimates put evaporation from Lake Nasser at between 10 and 16 cubic km per year. [29] Electricity production[edit] Power pylons at the power plant of the Aswan High Dam.

1 billion. [39] Health[edit] Skin vesicles: a symptom of schistosomiasis. A more common symptom is blood in the urine. Contrary to many predictions made prior to the Aswan High Dam construction and publications that followed, that the prevalence of schistosomiasis (bilharzia) would increase, it did not. [40] This assumption did not take into account the extent of perennial irrigation that was already present throughout Egypt decades before the high dam closure.
