Geoelectrical analysis for evaluating the aquifer hydraulic characteristics in Ain El-Soukhna area, West Gulf of Suez, Egypt

Abstract
Ain El-Soukhna area is an important industrial area for building and construction, so we used the subsurface shallow geophysical method, as represented by geoelectric resistivity measurements (Vertical Electric Sounding (VES)). These are processed and interpreted in the forms of a geologic model composed of five geoelectric layers of varying resistivities, lithologies, depthsand thicknesses. The thickness and true resistivity maps of the different layers and 2D geoelectric cross sections are generated for the represented layers to delineate their spatial distribution. The geoelectric Dar-Zarrouk parameters (Transverse Resistance and Longitudinal Conductance) were used to evaluate the electric anisotropy and aquifer hydraulic characteristics; such as hydraulic conductivity and transmissivity within the aquifer, as well as the groundwater quality (salinity of the aquifer) are estimated the true resistivity values acquired on the surface through the geoelectric resistivity survey.
