    abstract = {Geoelectric soundings have been carried out around the KWA IBO River watershed in Ikwuano and Umuahia, southeastern Nigeria. The geology of the area (Benin Formation) mainly consists of fine-medium-coarse grained sands. The data of eleven Schlumberger Vertical Electrical Soundings (VES), with a maximum AB/2=500 m, were analyzed using the resist software. The layer parameters thus obtained were used to calculate the Longitudinal Conductance (S) and the Transverse Resistance (T) distribution. Assuming the sandy aquifer is homogeneous and using the existing lithologs and pumping test data, data analysis was done to arrive at the Hydraulic Conductivity (K) and Transmissivity (T<SUB>r</SUB>) distribution within the study area. Aquifer characterization of the area also showed that the resistivity range is between 400-350WM and aquifer thickness ranged between 68 m near Usaka Elegu and 325 m near Government College Umuahia. From the results obtained, aquifer hydraulic conductivity and transmissivity values in most parts of the Watershed were observed to be high. Average aquifer transmissivity was 1722 m<SUP>2</SUP>/day. In general sandy aquifer are known for their excellent groundwater potential due to the fact that the (K) values in such aquifer are high. The thick sandy aquifer exhibits high transmissivity values, which reflect the geological setting of typical sandy formation. Based on the above analysis potential aquifer zones have been identified for regional groundwater development.}
