Geo-Electrical Investigation for Groundwater Potential of Ihievbe Ogben, Edo North, South Western Nigeria
SALAMI, SA & OGBAMIKHUMI, A
Abstract
This study was carried out within Ihiebe Ogben community in Akoko Edo LGA, Nigeria to
investigate the ground water potential of the Basement Complex rocks using Vertical Electrical Sounding (VES) that
deploys Schlumberger Array configuration. Evaluation of hydrogeological parameters shows fractured/ weathered
basement thickness, resistivity values of the fractured basement, overburden thickness and basement relief having values
between 1.5-7.9m, 64.5-503.9 Ωm, 5.2-15.7m and 136.8-160.7m respectively. Prospectivity ranking map was generated
from these parameters and was used to rank the area around the VES stations. The results show that the most
prospective areas with the highest ranking of 8,7 and 6 correspond to areas around VES station 6,1 and 2 respectively,
restricted to the Eastern – Northwestern region of the study area.
