Surface geophysical investigations, in addition to hydrochemical measurements were made on some locations at the western part of the River
Nile, Assiut. All the geoelectrical sounding measurements were made using the D.C. resistivity method. The geophysical results were
integrated with all available geological and hydrogeological information in order to recognize the probability of presence of water-bearing
formations, either fresh (low resistivity) or polluted (extremely low resistivity). Two conductive wet zones (shallow and/or deep) were
detected. Also, two extremely high resistive zones can be recognized; the first represents the surface dry zone (consisting of dry sands and
gravels), whereas the second is deeper in the entire surveyed area and may represent the bed rock (e.g. limestone). Only one extremely
conductive zone (< 20 Ohm-m) especially near and at the cultivated land in El-Madabigh and Beni-Adi is present, which may correspond to
clayey sediments or a polluted zone. The hydrochemical data show that the salinity decreases along the regional direction of the groundwater
flow and also along the sewage water movement in the irrigation canals.
