Abstract

Nineteen vertical electrical soundings (VES) were measured on the surface in the area east of Sohag to provide hydrogeologic information useful in groundwater exploration. These soundings are interpreted using automatic processing and interpretation programs of Schlumberger sounding curves prepared by Zohdy (1989 b). The results of the interpretation indicate the presence of a shallow water-bearing layer especially in the southern part of the area. This layer is diminished toward the east. In certain parts, the low-resistivity material could not be considered as water-bearing bed but it is possibly related to a shale bed dominating the area. The SP and horizontal resistivity measurements taken in certain directions (AA' and CC') show lateral variation of sedimentary facies in these locations.
