Groundwater is a vital resource in arid and semi-arid regions, such as Ethiopia’s Jimma Borena zones, where surface water availability limited. This study employs Geographic Information Systems (GIS), Remote Sensing (RS), the Analytical Hierarchy Process (AHP) to delineate groundwater potential zones. Key hydrogeological parameters, including lithology, slope, land use/land cover, drainage density, recharge, were analyzed weighted using AHP generate suitability maps. The findings indicate that Jimma, 4.6% of area highly suitable for development, 24% moderately suitable, 70% has low suitability. In Borena, 6.2% 42.6% 51.1% exhibits due topographic geological constraints. Validation borehole data confirms model’s reliability, demonstrating strong agreement with observed yields. These results provide cost-effective approach exploration highlight necessity geophysical surveys complex terrains enhance mapping accuracy. offers valuable insights planners policymakers, supporting sustainable management strategies region.
