The study of geo-electrical resistivity provides critical insights into subsurface characteristics and aquifer dynamics, particularly in regions with varying geological formations. This research investigates the efficiency of Vertical Electrical sounding (VES), a geophysical technique, for groundwater exploration within the hydrological setting of Uwasota Benin city, southern Nigeria. The primary aim of this study is to characterize the geo-electrical layers, assess aquifer thickness and resistivity. A total of 4 VES was acquired using Schlumberger electrode array. The data was interpreted quantitatively using the partial curve matching and computer iteration techniques to generate the first order geo-electric parameters and to also delineate subsurface lithological variations and identify potential aquifer zones.
