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.

It might be difficult to find possible groundwater reservoir zones, especially in arid or hilly regions. In the twenty-first century, remotely sensed satellite imagery may present a new opportunity locate surface and subsurface water resources more quickly affordably. order identify potential current study was conducted Central Saudi Arabia, southwest of Riyadh. The analysis employed multi-criteria approach that relies on remote sensing geographic information systems. variables this technique include geology, rainfall, elevation, slope, aspect, hillshade, drainage density, lineaments Land Use/Land Cover (LULC). Analytical Hierarchical Process (AHP) used for assigning weights parameters, corresponding significance each parameter’s several classes potentiality. Different zones were identified by study: very high (16.8%), (30%), medium (26.7%), low (18.6%), (7.9%). Only two observation wells located “medium” zone, but other ten observed “very high” according validation survey. Consequently, results demonstrate approach, which combines improved conceptualization with AHP define map has greater chance producing accurate can reduce threat drought broader

Investigation of the recurrent flash flood events in the Far-North Region of Cameroon

Research Square (Research Square), Год журнала: 2024, Номер unknown

A flash flood is a natural phenomenon generally occurring in regions with dense and compact rainfall. The arid Far-North Region of Cameroon (FNRC) subject to such climate conditions which result recurrent events. Those events often cause numerous deaths important property damage. This article aims at mitigating reducing risks the FNRC using GIS-based multicriteria decision-making technique. For this, data were collected from radar sensor ALOS PALSAR 2, optical Landsat 9 Operational Land Imager (OLI), WorldClim 2. From aforementioned datasets, ten influencing layers, namely curvature, drainage density, elevation, distance rivers, lakes, land use/land cover (LULC), rainfall, slope, stream power index (SPI) topographic witness (TWI) prepared, normalized, combined on GIS environment. resulting map susceptible zones (FSZ) reveals two-fifths seriously threatened by FSZ are clearly demarcated mapped, this paramount importance for sustaining safe settlements FNRC. In context scarce ground data, as where there single rain gauge located airport, remote sensing-analytical hierarchy process effective investigation. approach can help analysis other world.
