The research aimed to identify groundwater potential zones in the Kaduna South and Kaduna North Local Government Areas of Kaduna State, Nigeria. To achieve this, the study employed a multi-criteria decision-making (MCDM) approach using the analytical hierarchy process (AHP), along with remote sensing and geographic information systems (GIS). Seven thematic layers were analysed to delineate these potential groundwater zones, including land use and land cover (LULC), drainage density, lineament density, geology, slope, rainfall, and elevation. The findings indicated a spatial variation in the distribution of groundwater potential zones (GWPZs) by assessing the relative importance of each thematic layer through AHP and integrating all layers via overlay analysis in a GIS environment. The very high groundwater potential zone comprises 17.24% of the study area, covering approximately 24.43 km². High groundwater potential zones comprise 30.04% of the total area, with an estimated coverage of 42.57 km². Moderate groundwater potential zones account for 31.98% of the total area, covering about 45.32 km², while low groundwater potential zones represent 14.09% of the total area, with an estimated coverage of 19.96 km². Lastly, very low groundwater potential zones constitute 6.65% of the total area, covering around 9.42 km². This study offers valuable insights for decisionmaking and the development of effective groundwater management strategies.
