Abstract: ABSTRACT Groundwater is crucial for urban and rural water systems, especially as demand increases from climate change and population growth. This study addresses a gap in previous research on Groundwater Potential Zones (GWPZ). Drainage density, rainfall, slope, land use/land cover (LULC), soil, and geology, along with elevation were analyzed using ArcGIS and Remote Sensing with a weighted overlay method. GWPZs for Liandrindod Wells Watershed, Wales, UK is mapped using Multi-Criteria Analysis and Analytical Hierarchical Processing. Rainfall amounts range from very low (70–92 mm to very high (127–141 mm). The slope ranges from 0 to 195 degrees, with low slopes indicating high groundwater potential and high slopes indicating low potential. The LULC forming the region were water land, built-up area, cropland, rangeland, and treeland. The sub-basin soil falls into four distinct types: loam, sandy loam, sandy clay loam, and clay loam. The majority of the sub-basin is covered by rocks from the Silurian and Devonian periods. The following five zones make up the GWPZ map: Very High (147.7 km2) (2.9%), High (1943.4 km2) (38.3%), Moderate (2318.7 km2) (45.7%), Low (662.2 km2) (13%), and Very Low (4 km2) (0.08%). Groundwater-rich regions comprise about 87% of the study area.
