Earth Resistivity And Self-Potential Study On The Area East Of Sohag City And Their Groundwater Implications

Abstract

Nineteen field vertical electrical soundings have been made in the area east of Sohag to provide hydrogeologic information for groundwater exploration. These sounding are interpreted using programs for the automatic processing and interpretation of Schlumberger sounding curves prepared by Zohdy (1989B). Results of the interpretation indicate the presence of shallow water-bearing layer especially in the southern part of the study area. This aquifer is missing towards the east. In certain parts, the low-resistivity material cannot be explained as a water-bearing bed but it is possibly related to a dominated shale bed. The SP and horizontal resistivity profiling measurements taken in certain directions show lateral variation of sedimentary facies.
