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 northeastern 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.
