Application of the resistivity method to study ground water potentialities on a part of the entrance of wadi el-assiuti, Eastern desert, Egypt

Abstract

Wadi El-Assiuti is located east of Assiut city and extends in almost northeast direction. The entrance of the wadi is suitable site for reclamation and city planning projects. Consequently, it is very important to study the groundwater potentialities of this part of Assiut governorate. Electrical resistivity measurements included 29 vertical electrical sounding (VES) applying Schlumberger layout were carried out. The obtained VES-curves were quantitatively interpreted to deduce the corresponding geological layers, its true resistivities and thicknesses using the available computer program. The results of quantitative interpretation indicated presence of two possible water-bearing layers. The first is expected at depth ranging between 13 and 47 m with thickness varies between 20 and 70 m. A second possible aquifer is expected at the eastern part of the area and is characterized by depth ranging between 110 and 130 m and thickness between 60 and 80 m. The results of drilling data obtained at VES station 5 emphasized the data obtained from the quantitative interpretation of the VES-curves in the studied area.
