AbstractThis papers aims to study water and electricity for sustainable development around Qattara Depression in Egypt. This study suggests target level ranging from 170-165 (m) rather than 175 (m) upstream High Aswan Dam (HAD) and release the water for cultivation purposes in the Old Delta land from Assiut to Qattara Depression. Historical data for (HAD) was collected to compare target level, release, evaporation, and hydroelectric energy value from (HAD). The irrigation requirement for Old Delta cultivation was estimated according to soil type and Evapotranspiration. The hydropower generation from Qattara Depression before and after filling time was studied. The result of this study shows that target level of 170 (m) is a perfect solution for smart operation for (HAD) that could be used for agriculture and hydroelectric generation purposes, especially in high flood seasons when excess water released to Toshka spillway and evaporated. The hydroelectric power generated in Qattara Depression does not need filling time, high cost building dam, and more easier to export electricity to Sudan, Ethiopia and Europe through electric networks.
