The dam has a volume of 43 million cubic meters of cement, iron, and other materials. A water flow of 11,000 cubic meters of water per second may pass through the dam. Construction of the dam began in 1960 and the total cost was estimated at one billion dollars, one third of which was written off by the Soviet Union. He worked on building the dam 400 Soviet experts and completed its construction in 1968. The last 12 electric generators were installed in 1970 and the dam was officially opened in 1971. But the high dam reduced the fertility of the Nile River and did not replace the estuaries in Damietta and Ras El Bar with silt, which threatens to flood the delta after some more A hundred years ago, due to some other factors such as global warming and melting ice in the Arctic and Antarctic with a negative effect of the ozone layer. It should be noted here that the first to indicate the construction of this dam is the Arab Muslim scholar Al-Hassan bin Al-Hassan bin Al-Haytham - (he was born in 965 AD and he died in 1029 AD). And who did not have the opportunity to implement his idea, due to the lack of necessary machines to build it during his reign.
