Geophysical Investigations of Lithology and Ground Water Potentials of Recharge Zones (original) (raw)

International Journal of Multidisciplinary Research and Development, 2015

Abstract

Vertical Electrical Sounding (VES) with Schlumberger configuration were conducted at river Matan Fada, Argungu area of Kebbi State, North-western Nigeria. The Area is overlain by Gwandu Formation which consists of massive clays, clay grits, sandstones, mudstones and siltstones. A total of fourty (40) VES was carried out in the study area with maximum electrode spacing of 200m. The primary parameters ‘r’ and ‘h’ and Dar-Zarrock parameters T, S, and λ were determined by curve matching and computer iteration modeling, using (Winrest) software in the sedimentary formation of the study area to demarcate ground water potential recharge zones. Maximum of five geoelectrical layers of different lithology were delineated from the VES data. The groundwater potential zones were then classified with respect to the prospect of finding groundwater in the study area as poor, moderate and good zones. Low resistivity, coupled with good aquifer thickness are found at the middle part of the area that c...
