Abstract

The aim of this research is to carry out hydro geophysical study of Oyo State industrial estate Ogbomosho with a view to determining the areas that are good for groundwater prospects and the areas that are not suitable for groundwater exploration. Vertical Electrical Sounding (VES) method was used to map Oyo State industrial estate Ogbomosho which lies within latitude 08°06' 07.4" and 08°06' 25.4" North and longitude 004° 15' 03.3" and 004°15' 49.0" East of Southwestern Nigeria. Ten Vertical Electrical Soundings (VES) were carried out across the area using the schlumberger electrode array configuration with current electrode separation (AB) varying from 130 to 200 m. Nine out of the ten modeled curves were H-type where the remaining one was KH-type. The geoelectric sections obtained from the sounding curves revealed 3-layer and 4-layer earth models respectively. The models showed the subsurface layers categorized into the topsoil, weathered/clay, fractured layers and the fresh bedrock. The weathered basement and fractured basement are the aquifer types delineated for the area. Flow net and bedrock relief map showed that the Southern, Northeastern and towards the base of Northwestern direction of the study area are good for borehole development.
