Geophysical Investigation of Groundwater Using Vertical Electrical Sounding in Mubi and Maiha Local Government Areas of Adamawa State, North Eastern Nigeria

Abstract

This research work is aimed electrical resistivity survey for groundwater development conducted in Mubi and Maiha local government area of Adamawa State, in order to delineate the groundwater potential zones and determining the depth and thickness of sediments layers, and recommend suitable depth for drilling. Fourteen vertical electrical soundings (VES) were carried out within the study area using Schlumberger electrodes configuration was used for the field data acquisition. The field data obtained was analyzed using IX1D computer software and, VES1-14 resistivity model indicate 3-4 layered earth models. The interpretation shows positive inference in terms of a well-defined weathered basement and as such, it is likely to possess requisite hydro-geological characteristics that could supply underground water in fair quantity to well when drilled. Therefore, VES number denoted (R) are recommended for drilling at approximate depths of 40±5 to 50±5 meters.
