Six thematic layers: elevation, slope, drainage density, rainfall, land cover, and soil type are prepared and integrated for the spatial analysis. The analysis applies the multi-criteria-based Analytical Hierarchy Process (AHP) to obtain each layer's weight. The thematic layers with the assigned weightage are overlain in a weighted overlay analysis to develop the study area's potential groundwater recharge zone map. Potential recharge zones are classified into four categories: very low, low, medium, and high. The result shows that the medium zone occupies a large portion of the watershed's central and southern regions. The study also reveals that the high and low zones cover a minimal watershed area. The findings can help policymakers make informed decisions for sustainable management of groundwater resources of the study area. http://pubs.sciepub.com/ajwr/10/1/3/ajwr-10-1-3.pdf Geographical Information System (GIS) Analytical Hierarchy Process (AHP) Potential Groundwater Recharge Zone Mapping Watershed Delineation Weighted Overlay
