Groundwater availability in semi-arid regions like the Widyan Basin, Kingdom of Saudi Arabia (KSA), is a critical challenge due to climatic, topographic, and hydrological variations. The accurate identification groundwater zones essential for sustainable development. Therefore, this study combines remote-sensing datasets (Sentinel-2 ASTER-DEM) with conventional data using Geographic Information System (GIS) analytical hierarchy process (AHP) techniques delineate potential (GWPZs). basin’s geology includes Pre-Cambrian rock units Arabian Shield southwest Cambrian–Ordovician northeast, Saq Formation serving as main aquifer. Six soil types were identified: Haplic Calcic Yermosols, Calcaric Regosols, Cambic Arenosols, Orthic Solonchaks, Lithosols. topography varies from steep areas northwest nearly flat terrain northeast. Hydrologically, basin divided into 28 sub-basins four stream orders. Using GIS-based AHP weighted overlay methods, GWPZs mapped, achieving model consistency ratio 0.0956. categorized excellent (15.21%), good (40.85%), fair (43.94%), poor (0%). GWPZ was validated by analyzing 48 water wells distributed area. These range fresh primary saline water, depths varying between 13.98 130 m. Nine wells—with an average total dissolved solids (TDS) value 597.2 mg/L—fall within zone, twenty-one are fifteen classified remaining fall TDS values reaching up 2177 mg/L. results indicate that central zone area suitable drilling new wells.

Groundwater is one of the most valuable natural resources, and dependable source fresh water. For sustainable groundwater management, present study aimed to model potential zones in north–central region Bangladesh using GIS, remote sensing, analytical hierarchy process. The included eight thematic layers: lineament density, geomorphology, soil types, slope, land use/land cover, drainage elevation, rainfall features delineate a zone area. Integration layers was performed through weighted overlay analysis, which assisted delineating zones. This simple systematic method successfully provides satisfactory result concerning delineation resulted map, identifies about 11.51% area as being under very high zone, covering an 504.09 km2. AHP analysis shows that physiographical parameters, such meteorological factors annual rainfall, have greater influence over potentiality. obtained from verified with actual well yield depth data, show significant positive correlation. outcome will help taking effective measures ensure use extraction this region.

Groundwater supplies have been exploited because of global water shortage. Therefore, effective management resources is crucial. Identifying potential groundwater regions in arid and mountainous terrains challenging for many developing nations a lack financial human resources. An integrated strategy using remote sensing, geographic information systems, multi-criteria decision analysis the hierarchical analytical process was used to identify zones Gulufa Watershed, Blue Nile River Basin, Ethiopia, which covers 1700 km2. Nine groundwater-influencing thematic layers were produced from conventional satellite data, including lineament density, lithology, slope, geomorphology, soil, land use/land cover, drainage rainfall, elevation. Satty scale values their classes determined based on experts' opinions literature. Thematic maps weights rates produce zone map ArcGIS weighted overlay spatial function tool. According results, prospect consists 383 km2 very high, 865 350 moderate, 58 low, 0.3 poor zones. Validation existing boreholes yielded close agreement, demonstrating method's accuracy. removal sensitivity more sensitive lithology than other layers. The created research region can be an essential reference identifying locations additional resource exploration, planning, management.

Electric vehicles (EVs) are one of the most practical solutions to energy issue and environmental pollution. In recent years, EVs have developed rapidly, but still limited by charging problems. The emergence photovoltaic stations can solve pollution location is critical in life cycle electric vehicles. this paper, a multiple-criteria decision-making (MCDM) method based on Geographic Information Technology (GIS) for optimal site selection proposed. First, literature reading expert interviews, index system was identified, including four aspects with total ten sub-criteria. Secondly, spatial database relevant evaluation criteria established using GIS, preliminary analysis conducted. Then, fuzzy DEMATEL (Decision-Making Trial Evaluation Laboratory method) applied assigning weights. potential sites ranked MULTIMOORA (Multi-Objective Optimization basis Ratio Analysis) method. model validated siting vehicle PV Qingdao, eight were identified stage, suitable locations finally selected through MCDM stage. Finally, reliability validity further verified comparative dual sensitivity analysis.

Number of wells drilled by private and public stakeholders, as well nongovernmental organizations in the Menoua Division are unproductive. This is due to lack preliminary surveys assessing groundwater potential (GWP). A combined remote sensing (RS) analytical hierarchy process (AHP) approach handled on a geographic information system (GIS) environment efficient for such an investigation. For this article, seven environmental parameters, with significant contribution occurrence, integrated. Those parameters drainage density, elevation, lineament land use/land cover (LULC), rainfall, slope, topographic wetness index (TWI). RS GIS techniques said be quick simple exploring GWP whatever geological settings, have advantage investigating large areas little financial resources. Although these widely used world, first time they applied Division. The outcome, which sound map, has been sorted into five zones: very low 13 %, 27 medium also high 23 11 % may help reduce rate noncompliant hydrogeophysical number unproductive boreholes converging sites.

Abstract Remote sensing (RS) and Geographic Information Systems (GIS) have become widely used in various fields around the world recent years. In this paper; we attempt to delineate groundwater potential zone transboundary watershed of Chott-El-Gharbi using integration RS, GIS methods. Eight influencing thematic layers viz. geology, rainfall, water table level, lineaments density, slope, drainage elevation, land use/land cover were used. Afterward, Analytical Hierarchy Process technique, which offers good functionality for mapping potentiality was used, where ranks weights, assigned each factor are computed statistically, based on their relative importance terms potential. Then, zones classified into five categories namely excellent, high, medium, low, very low zone, represent 964.48 km 2 (7.33%), 1467.30 (11.15%), 7969.51 (60.57%), 2639.52 (20.06%), 116.19 (0.88%) study area, respectively. The region is found southern covered by mountains. Moreover, excellent located at central part Chott, has quaternary formations infiltration high. On other hand, moderate poor bare lands area. Finally, results carefully validated with yields data boreholes reveals an accuracy achievement 72.41%. finding research constitutes a valuable contribution towards resources management, it forms significant decision support tool equitable sustainable utilization Chott-El-Gharbi. study's findings will also serve as benchmark future studies, such hydrogeological modeling.
