| Abstract | ||||
| The middle part of El-Qaa Plain is one of the promising areas in Sinai Peninsula regarding its possible integrated development, based mainly on local groundwater resources. The main objective of the present work is to recognize the hydrologic characteristics of the Quaternary aquifer, which is the main groundwater resource in the area. A geoelectrical survey, conducted through 39 Vertical Electrical Soundings (VES), was found necessary first to reveal the rock succession in the area, including the aquifer. The interpretation of the VES data yielded good information about the depth, thickness and extension of the aquifer. The geoelectrical data, together with the available well information enabled in calculating the water level (1-22m), groundwater flow rate with direction (0.071 to 0.03 m/day), hydraulic conductivity (10-71.5m) and transmissivity (100- 1400 m2/day). Chemical analysis of water samples indicated that low salinity is associated with areas of high hydraulic conductivity, transmissivity and flow rate. By discussing the results and conclusion it was possible to reach useful recommendations regarding the favorable sites of the future drilling of the water wells, total depth of wells to be drilled in the different parts of the area and optimum pumping rate of some of the already working water wells. | ||||
