Dewatering using groundwater modelling in Al-Fustat area, Old Cairo, Egypt

The purpose of this study is to find a solution for the groundwater uprising in Al-Fustat area – Old Cairo, Egypt. A 3-D finite Difference Model (Visual MODFLOW-Ver. 3.1) has been used to simulate the impact of different alternative solutions in order to select the best suitable one. The result of geophysical survey, twenty bore holes data, hydro-geological data and satellite images were used to construct and calibrate the numerical model of Al-Fustat city. Finally, the recommended solution is a combination of pumping wells and tile drains. The results of this solution indicate that using pumping rate of 200 m3/day achieves 2–3 m drawdown which meets the target
