Abstract

Construction of dams results in both positive and negative environmental impacts. Sometimes the adverse environmental impacts extend to affect other countries of the river basins in case the river is an international one such as the River Nile. On 31 March 2011, the Grand Ethiopian Renaissance Dam (GERD) project was made public. Once impounding of the GERD reservoir begins, it will produce negative impacts on Egypt especially if filling occurs during low flow periods. The international panel of experts that formed on 11 April 2012 and submitted its final report on May 31, 2013 stated that the initial trans- boundary environmental impact assessment report concludes that the main adverse impact in Egypt will be a reduction in power generated at Aswan High Dam due to a fall in the water levels of Lake Nasser. Furthermore, during GERD impounding, there could be an irrigation deficit in dry years. This highlights the importance of this research paper which comes on line to quantify the shortage of water in the active storage of Lake Nasser due to impounding of GERD reservoir. Different scenarios of impounding will be considered as 6, 3 and 2 years under different inflow conditions. Mathematical modeling using MODSIM software was used to test these scenarios. The results indicated that the negative impacts on Egyptian water resources are severe specially if the filling period is shorter than 6 years. In turn, Egypt water policy and management should be modified to overcome this deficit of water at least during the six years of filling and negotiation should continue with the upstream countries Ethiopia and Sudan to solve the water conflict between them otherwise, Egypt will face many severe environmental, economic and social problems if the GERD is completed and used for storage purposes rather than for hydropower generatio
