Egypt would face terrible water shortage due to population growth and the progress of desertification. The aim of this study is to discuss the possibility of sustainable use of groundwater at around the Lake Nasser taking into account both naturally recharged water and pumping-induced recharge from the lake to subsurface. We first analyzed temporal change of groundwater heads caused by the changes of lake water level to obtain hydraulic conductivity of the aquifer. Then, the distributions of groundwater heads were simulated with respect to several different scenarios of pumping. Results of the simulations showed that well-chosen location and appropriate amount of pumping can enable us to use groundwater in sustainable way.
