Abstract

The Fayoum basin of Egypt is a closed basin with a lack of natural drainage outlets. In order to assess alternative water management scenarios, a basin- scale model was developed and tested, simulating water balances in the Fayoum basin and Lake Qaroun under present conditions. The model can simulate and evaluate the effect of some water management options such as the increase in drainage water reuse and the improvement of water distribution with time. The model results were evaluated with respect to measured Lake Qaroun water levels in 1980-1996. By comparing values computed for five statistical parameters, the predicted water levels were deemed to be in accord with measured values. The monthly modeling efficiency (EF) ranged from 0.65 to 0.91. On an annual basis. EF was estimated to 0.89. Based on the performance of the syst
