Geophysical study of the aquifer characteristics along River Niger, Delta State, Nigeria

Abstract

Geophysical survey was carried out in order to study aquifer characteristics (such as the depth, thickness and nature of soil materials above it) in the major communities along River Nigeria. Schlumberger vertical electrical sounding was conducted at Anieze, Obeza, Asaba-Okpai, Akashakpu, Obobo-Oyibo, Okpai, Oluchi, Umu-Ugboma, Iyede-Ame, Umuti-Agboh and Aboh town. The resistivity soundings were carried out with half electrode spacing in the range 1-681m and six point per decade. The results were used to determine the depth, thickness of the recommended aquifer and the thickness of clay above it. The results showed a recommended aquifer of thicknesses, 14.40-68.75m at depths, 21.65-34.20m, and a clay of thicknesses, 0-10.80m above it.
