“…These layers were weighted, normalized, and assigned features based on local field experience, professional judgment, and Saaty's AHP. 9,10,14,37 The study obtained a CR value of 0.09, which is acceptable to continue the AHP-based potential mapping analysis. The study revealed that the northern side of the district, which includes high-elevation ranges and river valleys, has a high concentration of poor and very poor (18.804%) potential areas.…”

In the current climate change scenario, natural spring in the region is drying or vanishing, increasing water scarcity. So, to protect this vital resource, spring rejuvenation and protection activities are needed. Thus, the region spring potential zones (SPZ) must be identified to execute the project successfully. The current study used remote sensing (RS) and geographical information system (GIS) techniques to determine an SPZ based on multicriteria decision-making (MCDM) and an analytic hierarchy process (AHP). The SPZ map was created using eight spring-influencing parameters and showed that the medium potential zone had the highest area (55.6%), followed by high (24.3%), poor (18.804%), and very high (1.3%). The AUC validation score was 0.714, indicating good prediction accuracy. The study recommended implementing artificial rainwater harvesting structures and protection measures to rejuvenate springs for long-term sustainable water supply in very high to medium potential zones, representing 63.73% and 29.67% of the identified spring locations, respectively.

“…Land use practices have an impact on the timing, volume, and quality of groundwater recharge, as well as in uencing runoff and evapotranspiration (Rather et al 2022). Regions covered with forests possess a greater potential for groundwater recharge, whereas areas with concrete structures have less capacity for recharge (Sajil Kumar et al 2022). In this study (Fig.…”

“…The slope is a signi cant geomorphological characteristic that in uences the potential of groundwater in an area. It is a crucial parameter in assessing the possibilities for groundwater recharge (Sajil Kumar et al 2022). In places where the slope is low, excessive seepage occurs due to the accumulation of surface water.…”

Groundwater provides most of the freshwater needs such as drinking, irrigation and industry. As a result of increasing population, urbanization and industrialization, groundwater resources are faced with the risk of decreasing and pollution. For this reason, Konya in Türkiye, having a lot of agricultural activities, was chosen as the study area. This research utilized the analytical hierarchy process (AHP), a type of multi-criteria decision-making analysis, to assess the groundwater potential in Konya, Türkiye. For this purpose, land use, slope, rainfall, topographic wetness index, drainage density, elevation, plan curvature, profile curvature and stream power index thematic maps were created, and their weights were determined with AHP. Groundwater potential map (GWPM) was produced by overlay analysis in GIS environment. The GWPM was validated by comparing it with the groundwater zones (GWZ) map given in the report of “Konya Closed Basin Management Plan” project. As a result of the validation process, the accuracy value was found to be 0.87.

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