Overexploitation and climate change have threatened the availability sustenance of groundwater resources. A proper understanding regional distribution is crucial to ensure long-term water security. The present study aims identify potential zones in Lakhimpur district Assam using Analytical Hierarchy Process (AHP) combination with geospatial technologies. occurrence region was determined by several factors including geomorphology, lithology, slope, distance from river, drainage density, lineament rainfall, curvature, soil, land use, cover, Normalized difference vegetation index (NDVI), topographic wetness (TWI). These organized as thematic layers were utilized generate a (GWPZ) map GIS environment. AHP, an effective decision-making technique, adopted assign weights each layer corresponding their relative importance influencing availability. GWPZ prepared weighted overlay techniques categorized into three classes: good, moderate, poor. result revealed that good zone comprises 1909.41 km2 (65.12%), moderate 1018.25 (34.72%) poor 4.22 (0.14%) total geographical area. obtained results 73.33% (Overall accuracy), 0.708 (ROC-AUC), 0.50 mbgl (groundwater level fluctuation) between pre-monsoon post-monsoon prove model has performed satisfactorily identifying zones. findings provide framework for exploration management resources, ensuring future region.

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.
