2D ERI for Groundwater Exploration in a Crystalline Basement Terrain, Abeokuta, Southwestern Nigeria
Electrical resistivity imaging (ERI) is widely used for near-surface characterization in geophysical applications for hydrogeological, environmental and engineering investigations. This study involves the application of the two-dimensional (2D) electrical resistivity imaging (ERI) to delineate structures that are suitable for groundwater occurrence in a crystalline basement complex terrain. The dipole-dipole array, which is sensitive to weathered and fractured zones commonly associated with groundwater accumulations in a basement complex, was deployed for the measurements. The survey was conducted to locate possible points for siting productive boreholes in a site at Abeokuta, southwestern Nigeria, as previous boreholes and wells drilled within the study site failed.
