Interpretation of geophysical and GIS-based remote sensing data for sustainable groundwater resource management in the basement of north-eastern Osun State, Nigeria

Abstract

This study describes the interpretation of integrated GIS-based remote sensing and electrical resistivity geophysical methods as part of the need to provide groundwater overview for sustainable management in the basement of north-eastern Osun State, Nigeria. Six groundwater conditioning factors are synthesized based on the analytical hierarchy process and multi-criteria decision analysis to produce groundwater potential index map constrained by existing borehole yields. The results indicate that the estimated groundwater potential index map can serve as a gross predictor of the groundwater distribution in the region. This study may influence town planning and land use decisions for sustainable management of groundwater resource in the area.
