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

Integrating geospatial, hydrogeological, and geophysical data to identify groundwater recharge potential zones in the Sulaymaniyah basin, NE of Iraq

Scientific Reports, Год журнала: 2025, Номер 15(1)

Abstract Groundwater is a critical resource for sustaining human activities, particularly in urban areas, where its importance exaggerated by growing water demands, expansion, and industrial activities. Ensuring future security necessitates an in-depth understanding of groundwater recharge dynamics, which are often complex influenced rapid urbanization. The alarming decline resources both rural regions underscore the urgency advanced management strategies. However, identifying evaluating potential zones (GWPZs) remains challenge due to dynamic interplay hydrogeological development factors. This study employs integrated approach combining geographic information system (GIS), remote sensing, multi-criteria decision analysis using analytical hierarchy process (MCDA-AHP) delineate GWPZs Sulaymaniyah Basin (SB). methodology further supported data validated through geophysical investigation electrical resistivity tomography (ERT) data. For MCDA-AHP, six thematic layers including rainfall, geology, lineament density, slope, drainage land use/land cover were derived from satellite imagery, geological surveys, well These ranked based on their relative influence GIS-based weighted overlay generate maps. results identified three recharge: low (11.26%), moderate (45.51%), high (43.23%). Validation ERT receiver operating characteristics (ROC) revealed strong agreement, with area under curve (AUC) accuracy 86%. findings demonstrate robustness approach, providing reliable tool minimizing hydrogeophysical exploration costs reducing number unsuccessful boreholes.

Extracting of prospective groundwater potential zones using remote sensing data, GIS, and multi-criteria decision-making approach in the Sub-Himalayan Dooars region of West Bengal, India

Applied Water Science, Год журнала: 2024, Номер 14(4)

Опубликована: Март 14, 2024

Abstract Groundwater is one of the fundamental sources fresh water. Currently, unequal distribution groundwater poses a significant environmental crisis, leading to scarcity in certain regions and affecting livelihood living organisms worldwide. The present study introduces Sub-Himalayan foothills Dooars, highly populated agriculturally based area. To delineate potentiality eight different effective parameters have been employed such as slope, geomorphology, soil, LULC, lineament, rainfall, hydrogeology, drainage density. For process development these thematic layers, geographic information systems satellite images (Landsat 8) used give normalized weight rank value each layer their sub-criteria. MCDA-AHP-based model for overlay analysis (GWPZ). After ArcGIS 10.2.2 final map further grouped into four zones, i.e., very high, moderate, low potential zones. A high zone encompasses 22.45 sq. km. southern portion selected region. 1613.32 km southeastern part, moderate covered by 1063.84 sq.km, 71.03 sq.km (2.56% area region) zone. available well data from CGWB utilized assess district, ensuring originality authentic validation. It found that there correlation between observed existing data. With growing population Dooars region, has corresponding rise demand Hence, this research would assist authorities policymakers effectively managing resources district.
