Abstract

An integrated geophysical survey including Vertical Electrical Sounding (VES), Transient Electromagnetic (TEM), and Electrical Resistivity Tomography (ERT) was conducted in the area of Wadi Sakhr, Northwestern Coastal Zone of Egypt. The objective of this survey is to characterize the conditions under which the groundwater occurs in the Middle Miocene carbonate rocks, which dominate the study area. The inversion results of 9 VES and 17 TEM measured sounding data revealed that the subsurface geoelectrical succession in most of the study area consists of five layers in addition to a sixth geoelectrical layer capping the succession at the northern part of the study area. The water-bearing zones were detected within the lower part of the third layer in the northern part of the area and the lower part of the fifth layer in the southern part of the study area. The inversion results of 11 ERT profiles revealed the detailed resistivity distribution of the subsurface layers and confirmed the results of both VES and TEM surveys. Besides, it resolved details of several subsurface features.
