ABSTRACT

Throughout the project, a comprehensive analysis was undertaken to assess the groundwater potential of the study area. By integrating diverse geospatial datasets encompassing geological, hydrological, topographic, and climatic information, we successfully identified and delineated groundwater potential zones based on their suitability for both recharge and extraction. Additionally, the study aimed to determine suitable zones for public borehole siting within the study area utilizing Multi-Criteria Decision Analysis (MCDA), notably employing the Analytical Hierarchy Process (AHP) technique in conjunction with GIS. The results of the groundwater potential zone mapping unveiled distinct spatial patterns and variations in groundwater potential across the study area. High-potential zones were predominantly situated in areas characterized by favorable hydrogeological conditions, such as permeable lithology, gentle slopes, high rainfall, and proximity to recharge sources. Conversely, low-potential zones were associated with impermeable substrates, steep slopes, and limited recharge areas
