INVESTIGATION OF THE DEPTH OF GROUNDWATER USING SEISMIC REFRACTION AND ELECTRICAL RESISTIVITY METHODS IN IBUSA AND OGWASHI UKU, DELTA STATE.
OKANIGBUAN, P. N. AND IGHODARO, E.
ABSTRACT
The Resistivity and the seismic investigations of the study areas have provided valuable information on the nature of the sub-surface layers. The geo-electrical section of the study areas shows five to six layered earths and the water bearing formation, Aquifer. From the VES in Ibusa and Ogwashi-uku, it was observed that the first layer ranges from 59.8Ωm – 100.5 Ωm with depth 0.6m – 1.2m, this is…
