GEO-ELECTRIC DETERMINATION OF GROUND WATER POTENTIAL IN PARTS OF OSUBI, DELTA STATE, NIGERIA
Abstract
ABSTRACT
Electrical resistivity survey employing vertical electrical sounding was carried out in Osubi, Southern Nigeria, involving a total of four soundings across, in order to assess the groundwater potential and the aquifer vulnerability in Osubi. This survey was conducted to determine the distribution of groundwater in the area The field data were interpreted using the WINRESIST software, and the resulting geoelectric curves give the resistivities, depths and thicknesses of each geoelectrical layer. Measurement data results are available in the form of 1D resistivity visualizations that are analyzed to determine groundwater distribution. In addition, we performed a comparative analysis of the accuracy of geoelectric measurement results using the results of data with different configurations. Based on the results of geoelectric measurements, we are able to find the aquifer depth related to a high probability of groundwater.
