The study area extended from El-Gora and its vicinities in the south to E1 Sheikh Zowyed and Rafah cities in the north. Quantitatively the water bearing formation in the area has been illustrated by applying the PMW1N (Processing Modflow for Windows) and modulus contour map techniques. Qualitatively, the groundwater is evaluated by an isosalinity distribution map. The hydraulic parameters of the water bearing formations were determined and evaluated through 12 pumping tests carried out on selected wells. On the other hand, the ground elevation of the study area is illustrated by a DEM (Digital Elevation Model). The DEM map indicated that the investigated area lies within a low land area. Due to the depths of groundwater (46.1-105 m from the ground surface), the rainfall replenishment is nearly absent. Based on the resulting modulus contour map, the northern and northwestern portions are characterized by reasonable potentiality of groundwater. Moreover, the eastern and southern portions reflect limited aquifer potentials. The mathematical modeling results revealed that the recharge to the investigated aquifer is about 9.794 million m3. 展开更多
