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.

Among all other valuable natural resources, groundwater is crucial for global economic growth and food security. This study aimed to delineate potential zones (GWPZ) in the Gidabo watershed of Main Ethiopian Rift. The demand supplies various applications has risen recently due rapid population upsurge. An integrated Geographical Information System, Remote Sensing, Analytical Hierarchy Process (AHP) been utilized. Eight regulating factors, including rainfall, elevation, drainage density, soil types, lineament slope, lithology, land use/land cover, have taken analysis. To assign suitable weights each factor, AHP was employed, as element contributes differently occurrence. weighted overlay analysis (WOA) technique then used ArcGIS environment integrate thematic layers generate a GWPZ map. delineated classified into five categories. poor covered 18.7 %, low 33.8 moderate 23.4 high 18.1 very 5.8 % area. Well spring data were validate model, ROC (Receiver Operating Characteristic) curve method applied. results showed good accuracy 76.8 %. result this research can be planning managing resources watershed.

Groundwater is an invaluable natural resource that sustains human life and supports the economic development of nations. However, its unsustainable utilization has emerged as a critical issue, particularly in developing countries. This study investigates groundwater potential Chemoga watershed to address these challenges. Conventional assessments have typically relied on labor-intensive time-consuming field surveys, which are resource-demanding often fail provide accurate estimates due inherent complexity systems. In response, this research utilizes geospatial analytic hierarchy process (AHP) techniques assess Watershed, aiming overcome Eight biophysical environmental factors: geology, slope, rainfall, land use/land cover (LULC), soil type, elevation, lineament density, drainage density were selected for analysis using Saaty’s AHP methodology. Data was gathered from satellite imagery, existing thematic maps, local water offices, national meteorological agencies. The integration maps performed through weighted overlay ArcGIS 10.8, resulted delineation zones (GWPZ). model validated by cross-referencing generated GWPZ with data dug wells boreholes. results reveal five zones: very high (0.73%), (24.39%), moderate (43.38%), poor (31.25%), (0.25%). most suitable south, southeast, southwest watershed, near Debre Markos Town. These high-potential significant 81.5% match ground truth shallow wells. findings crucial insights decision-makers, enabling formulation more effective management strategies. By identifying cost-effective well sites, contributes ensuring sustainable supply

The global groundwater crisis is a perplexing issue, and for its resolution, it of the utmost importance delineating potential zones. This research aims to create precise map Bangladesh's Jashore district by combining geospatial approach an analytical hierarchy process. Fourteen parameters, namely, lineament density, drainage land use cover, slope, curvature, topographic position index, wetness rainfall, geology, roughness, fractional impervious surface, topsoil texture, soil permeability, general types, were considered study after extensive literature review. weights these parameters determined using process, scores each sub-parameter assigned based on published literature. final was then generated weighted overlay analysis tool in ArcGIS 10.3 categorized into five classes. reveals that very high, moderate, low, low zones cover 3.96 km

The indiscriminate use of surface water has heightened the demand for groundwater supplies. Therefore, it is critical to locate potential sources develop alternative resources. Groundwater detection tremendously valuable, as sustainable management. Mersin, in southern Türkiye, expected confront drought shortly due increased population, industry, and global climate change. zones Mersin were determined this study by GIS-based AHP, VIKOR, TOPSIS methods. Fifteen parameters used goal. area was separated into five categories. results show that can be divided “Very High” (4.98%, 5.94%, 7.96%), followed “High” (10.89%, 10.32%, 16.50%), “Moderate” (60.68%, 52.41%, 51.56%), “Low” (21.28%, 28.53%, 20.90%), Low” (2.18%, 2.80%, 3.07%) turn. Data from 60 wells validate ROC-AUC technique utilized this.
