Water remains indispensable for survival of human, but the quality of groundwater of different places are influenced by impurities which causes pollution or reduction of the usability of the water
With the global population increase, it is expected that human anthropogenic activities will continue to impact water resources to build, expand, and maintain their socioeconomic development. Research has shown that 70% of the inhabitants rely on shallow groundwater resources of the region. Change in land use/land cover is one of the significant factors controlling regional hydrology and groundwater resources, thus the continuous change in land use and land cover of the drainage basin will significantly affect the basin's groundwater resources.
The research focuses on analyzing the spatial and temporal pattern of recharge to ascertain its effect on groundwater in West Africa. This was done using the WetSpass – M Model to estimate groundwater recharge. The result shows that 27% of rainfall in the Osun basin becomes groundwater while 43% is lost to evapotranspiration, 21% to surface runoff, and 9% to interception. This research calls for effective rainwater conservative measures to help store stormwater and aid groundwater recharge rather than having it run off on the surface which eventually results in flooding.
