    The delineation of groundwater potential zones in Ondo State was carried out using Remote Sensing, Geographic Information Systems (GIS) and Hydrogeophysics. In this study, various thematic maps such as: soil map, slope, drainage map, land use/Land cover map, geological map, rainfall map, lineaments map were obtained from enhanced satellite imagery. These maps were overlaid in terms of weighed overlay method using Spatial Analysis tool in Arc GIS 10.5. During weighed overlay analysis, different ranks were given to each individual parameter of each thematic map and weights were assigned according to their influence. Results showed that spatial distribution of the most promising sites for groundwater exploration was dependent on the interrelated factors of lithology, topography and geologic structure. The groundwater potential map obtained from the study area showed that 17.5% of the tot.. View More»
