Groundwater Potential Assessment Using Integrated Geospatial and Analytic Hierarchy Process Techniques (AHP) in Chemoga Watershed, Upper Blue Nile Basin, Ethiopia

Air Soil and Water Research, Journal Year: 2025, Volume and Issue: 18

Published: Jan. 1, 2025

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

Hybrid GIS-MCDM Based Modeling Approach for Determination of Land Suitability of Wheat Cultivation in Konya Closed Basin, Türkiye

Tarım Bilimleri Dergisi, Journal Year: 2025, Volume and Issue: 31(2), P. 427 - 446

Published: March 25, 2025

In countries with high population growth and migration potential, such as Türkiye, agricultural lands are gradually decreasing due to the increase in food demand misusage policies urbanization applied lands. Land suitability activities carried out within scope of sustainability order production soil productivity important. This study focuses on identifying suitable for wheat cultivation by evaluating Konya closed basin Central Anatolia Region Türkiye using a hierarchy developed integration AHP method, which is one GIS MCDM techniques. Within this framework, 15 criteria were delineated under 4 main headings meteorological criteria, topographic infrastructure economic their weight values sub-criteria calculated. The most effective determined average temperature October (0.1379), followed annual (0.1300) land use capability (0.1191). Finally, map was created cultivation. According map, 0.39% (15 815 km2) area found be very highly cultivation, 61.24% (2 494 461 terms suitability. districts Kadinhani, Sarayonu, Altinekin, Cihanbeyli, Kulu, Karapinar Emirgazi, located north area, have been regions aims contribute existing literature precise areas combining site selection process. study, new research perspective presented taking into account uncertainty process concept four different dimensions: meteorological, topographical, soil, economic, thus aiming guide decision-makers future studies. current literature, that no comprehensive has yet conducted covers large plant, raw material humanity's basic nutritional needs. addition, pressure criterion not examined discussed its importance plant development also examined. Consequently, outcome delineates methods used may guiding studies covering wide areas.

Evaluation of potentially susceptible flooding areas leveraging geospatial technology with multicriteria decision analysis in Edo State, Nigeria

Natural Hazards Research, Journal Year: 2024, Volume and Issue: unknown

Published: July 1, 2024

Floods have claimed lives and devastated societal ecological systems. Because of their catastrophic tendency the financial fatalities they cause, floods become more significant on a global scale in recent years. In Edo State, Nigeria, flooding is frequent threat that happens annually seriously damages both property. While potential cannot entirely be eliminated, geospatial-based technologies can greatly lessen its effects. Nigeria's flood-prone study's objectives are to identify inundated places provide nuanced mapping flood risk. To facilitate determination risk index (FRI), fundamental flood-predictive features were determined by taking into consideration elevation, slope, distance from river, rainfall intensity, land use/land cover, soil texture, topographic roughness index, wetness normalized difference vegetation (NDVI), runoff coefficient, aspect, drainage capacity, flow accumulation, sediment transport stream power index. The significance each predictive factor analytic hierarchy procedure (AHP) was gathering expert views perspectives public entities. A map created processing gathered data using AHP ArcGIS 10.5 framework. multicollinearity (MC) estimation applied assess model's predictability. results FRI showed there high extremely severe zones affected roughly 26 9% area, respectively. Flood risks been identified as predominant south region study which characterized low elevation wetness, It resultant vulnerability maps agreed with past occurrences previously experienced research demonstrating technique's efficacy locating locations plagued flooding. Linear regression (R2) analysis further conducted evaluate scientific reliability utilized methodology; this shows 0.816 (81.6%) dependability. Consequently, long-lasting implementation predictions, warning systems, mitigation strategies may achieved.
