摘要：

Southwest Egypt is an arid area with no surface water, but reasonable resources of useable groundwater in the well-known Nubian Sandstone Aquifer System. Currently, these groundwater reserves are being heavily exploited. A calibrated regional numerical model with grids refined on the major pumping centres has been used to investigate the hydrodynamic impacts of different groundwater management options on the potentiometry of the aquifers. The results indicate that there is a real threat of either dewatering the shallow aquifer in some areas (e.g. Kharga Oasis), or lowering of the water level to uneconomic lifting depths. It also indicates that although the planned extraction rates in Dakhla, Farafra, and Bahariya oases are feasible for at least the coming hundred years, the present extraction rate at Kharga Oasis, and the planned rate for the East Oweinat area have to be reduced substantially.
