Delineation of Groundwater Potential Zones (GWPZs) in a Semi-Arid Basin through Remote Sensing, GIS, and AHP Approaches

Groundwater occurrence in semi-arid regions is variable space and time due to climate patterns, terrain features, aquifer properties. Thus, accurate delineation of Potential Zones (GWPZs) essential for sustainable water resources management these environments. The present research aims delineate assess GWPZs a basin San Luis Potosi (SLP), Mexico, through the integration Remote Sensing (RS), Geographic Information System (GIS), Analytic Hierarchy Process (AHP). Seven thematic layers (geology, lineament density, land use cover, topographic wetness index (TWI), rainfall, drainage slope) were generated raster format. After AHP procedure rank assignment, integrated using calculator obtain map. results indicated that 68.21% area classified as low groundwater potential, whereas 26.30% moderate. Validation was done by assessing residence data from 15 wells distributed study area. Furthermore, Receiver Operating Characteristics (ROC) curve obtained, indicating satisfactory accuracy prediction (AUC = 0.677). This provides valuable information decision-makers regarding conservation resources.
