Résumé
Groundwater in Delta Wadi El-Arish, Sinai Peninsula, Egypt, constitutes an essential source of water supply. The number of wells has rapidly increased from the year 1980 to present days for domestic use and irrigation of local farms. Consequently, abstraction from the coastal aquifer is increased rapidly under non-sustainable conditions such as topographic and climatic conditions. So, the water table has declined and the water salinity has increased due to intruding of seawater through the water bearing formations. Management in this area needs a proper evaluation of Quaternary groundwater aquifer. Numerical model (MODFLOW) for flow simulation and (MT3DMS) for transport simulation are constructed, employed and calibrated under steady-state conditions to simulate groundwater aquifer in this area. This simulation model was, then, applied to test the behavior of the reservoir under three different scenarios for groundwater abstraction. These scenarios consider the future increase in pumping through the existing wells by 50% and 100% along with proposing new deep wells. Application of the developed model resulted in clarifying the effect of excessive pumping from the present wells along with newly drill wells
