摘要

The effective management of groundwater is important, as it is a crucial resource for sustaining life. Proper use and replenishment can resolve several environmental and societal issues. Groundwater table distribution, slope, landform, drainage networks, lithology, topography, geological structures, fracture density, land use, and land cover are some of the factors that affect the occurrence and productivity of groundwater in aquifer systems. By defining possible zones, geospatial technologies like Geographic Information Systems (GIS) and Remote Sensing (RS) are effective tools for assessing, tracking, and safeguarding groundwater to assess these impacts. Rainfall, geology, drainage density, lineament density, soil, slope, aspect, surface roughness, hillshade, land use/land cover, and flood data are among the twelve groundwater-controlling characteristics taken into account in this study. Weighted overlay analysis is used to assign a weight and class rank to each theme layer. A Groundwater Potential Zone (GWPZ) map is created after the results are confirmed by boreholes verification. Very low potential (13.5% of the region), low potential (24%), medium potential (36.5%), high potential (21%), and very high potential (5%) were the five categories used to categories the designated watershed. The southern part of the basin showed strong groundwater potential, whereas the northeastern part was classified as a low-potential zone. In particular, the high-potential zone spanned 388.35 km², while the low-potential area covered 10.47 km².The model’s 85% accuracy rate attested to the results’ dependability. To sum up: this study upholds the ideas of sustainable development and offers a useful scientific basis for efficient management of water resources.
