2d resistivity imaging survey for water-supply tube wells in a basement complex: a case study of OOU Campus, Ago-Iwoye SW Nigeria

Abstract

Groundwater search in hard and compact rocks of basement complex using 2-D resistivity imaging survey supported by 1-D vertical electrical sounding with Schlumberger array along the same profiles were carried out. Four (4) traverses with Wenner electrode configuration were established around the building complex. The results show 3-5 layers which signify different lithological units encountered as resistivity values were converted into geologically reasonable picture.
