ABSTRACT Managing water resources and storing through the identification of groundwater recharge zones (GWRZs) are critical to security in Egypt. Decision-support systems (DSSs), remote sensing, GIS techniques have yielded significant data for modeling. The geologic, geomorphic, climatic, hydrologic features Toshka area, Western Lake Nasser, Egypt, been generated by from Shuttle Radar Topography Mission, Climatic Research Unit gridded Time Series, Sentinel 2 time series, Landsat-8 OLI. Fifteen thematic maps ranked normalized using five DSS techniques: Analytical Hierarchy Process (AHP), Fuzzy process (FAHP), Frequency Ratio (FR), Shannon Entropy (SE), Multi-Influencing Factor (MIF). To ensure computational usefulness these models, GWRZs extracted compared. outcomes showed that 83, 87.5, 99.1, 87.5% existing wells high extreme AHP, FAHP, FR, SE, MIF, respectively. receiver operating characteristic curve (ROC) was used assess effectiveness models. It found SE model had highest predictive performance rates, as its ROC accuracy value 91.1%, while MIF approaches values 91, 84.4, 81.9, 89.9%,

The maintenance of ecological diversity, public health, and economic expansion depends on appropriately managing groundwater supplies. This study focuses the Markanda Watershed, a region characterized by its diverse topography, pressing issues such as over-extraction, seasonal water shortages, flooding. analytic hierarchy process (AHP) fuzzy AHP are two highly developed techniques scientific ideas used in this work to discover potential zones (GWPZs). GWPZs determined employing 12 thematic layers. Using both approaches, these maps weighted based their characteristics potential. Upon analysis with Fuzzy-AHP, four – low 0.034% (0.0124 km2) 13.535278% (4.8727 km2), moderate 44.59% (16.0532 and, 37.17% (13.3812 high 52.923% (19.0523 42.2575% (15.21217 very 2.450% (0.8821 7.0372222% (2.5334 were revealed that indicate different levels Validation through Receiver Operating Characteristics (ROC) indicates Fuzzy-AHP model achieves an accuracy 76.3%, compared 71.43% for model. Based study’s findings, targeted management plan is proposed optimize resource use sustainability. High-potential should be prioritized extraction recharge. Moderate-potential areas require balanced approach. Low-potential focus reducing dependence enhancing surface storage prevent overexploitation. These strategies aim ensure sustainable management, promote balance, support socio-economic development.
