Evaluation of soil profile on aquifer layer of three locations in Edo state

Abstract

This investigation was carried out in three locations (Ekpoma, Irrua, and Uromi) all in Esan central and North-East region respectively of Edo state, Nigeria. The aim was to find out how soil profile depth is related to aquifer layer. Verifying how relief and (physical properties) such as heat, temperature, and resistivity affects the aquifer layer. Result of the study proved that location, relief, and the factors, such as radiation, heat, temperature, resistivity and moisture contributed to either a low or high aquifer layer. Increased radiation resulted to increment in temperature, heat, resistivity, and less moisture content in the soil profile horizon. Whereas relief was an over riding factor that influence the aquifer depth. With maximum soil profile depth of 528.90, 476.67, and 495.96 m, the aquifer layers for Ekpoma, Irrua, and Uromi respectively indicated that relief played a prominent role as observed in their topography. Therefore in hydrological investigation the contribution of this study would give a guide on effective aquifer layer position in the studied location in Edo State Nigeria. Key words: Evaluation, soil profile, aquifer layer.
