%X The geological lineaments and drainage patterns from the SRTM DEM data of the section of southwestern Nigeria, covering Oyo and Ogun states, were extracted in order to investigate the groundwater potential of the study region. The main objective of this study is to delineate the geological structure of the region, to enhance near-future groundwater exploitation of the region. The SRTM DEM data utilized in this study covers the latitudes 7'00¡ãN to 8'00¡ãN and longitudes 3'00¡ãE to 4'00¡ãE. The data were analyzed for lineament density and lineament intersection. Similarly, flow direction and flow accumulation tools were applied to the fill sink SRTM DEM data to extract the drainage network over the study area. It was observed from the SRTM DEM Image that areas with low elevation exhibit the highest flow accumulation, as evidenced in the northeastern, Abeokuta north, Ibadan southeast, Ibadan northwest, Oyo east, Oyo west, and Iwajowa regions of the study area. This suggests a high groundwater potential, as water naturally flows from higher elevations to lower points. Some lineaments show alignment with the drainage patterns of the study area. These lineaments influenced the drainage system of the study area. It was observed that the flow of the drainage patterns in the study area coincided with or aligned with the Northwest-Southwest lineament orientation.
