Electrical resistivity and induced polarization imaging for groundwater exploration
Electrical methods of geophysics are widely used in addressing a variety of hydrologic problems including groundwater exploration, groundwater quality and contamination studies. This study presents the integration of electrical resistivity techniques with time domain induced polarization (IP) imaging for groundwater exploration in a sedimentary terrain, southwestern Nigeria. The subsurface was characterized to identify the lithologic units and delineate the underlying aquifer.
