Electrical Resistivity Method in Delineating Groundwater Potentials of Ikare Akoko, Southwestern Nigeria (original) (raw)

Journal of Global Ecology and Environment

Abstract

This investigation involves Vertical Electrical Sounding (VES) technique to detect the subsurface conductive zones as the groundwater potential zones within Ikare Akoko, southwestern Nigeria. Fifteen vertical electrical sounding were conducted using the SAS 1000 Terrameter equipment in E-W direction across the site using schlumberger array and horizontal profiling to narrow down the area of interest. Possible groundwater flow paths identified as conductive zones. The results showed that the conductive zones has the highest point with good aquifer apparent resistivity values with relatively thick overburden which were the major factors in determining the groundwater potential in the study area while those carried out on the non-conductive zones has the lowest point on the graph and were characterized by poor indication to groundwater potential of the area. The probable station more suitable for borehole construction in the study area were stations VES 1, 2, and 3 depicting high aquif...
