Unleashing the Untapped Potential: Groundwater Exploration in a Watershed Environment of North‐East India Using MCDA‐AHP Techniques

Hydrological Processes, Год журнала: 2025, Номер 39(1)

Опубликована: Янв. 1, 2025

ABSTRACT The contemporary era is marked by the faster exploitation of groundwater resources due to combined effects burgeoning population and rapid industrialisation. This study tries delineate potential zones (GWPZs) in a fragile agriculturally dominant watershed North‐East India using GIS‐based multi‐criteria decision analysis (MCDA) approach Analytical Hierarchy Process (AHP) technique. has undertaken 10 influencing factors: geomorphology, geology, land use/land cover (LU/LC), drainage density, rainfall, soil texture, slope, lineament topographic wetness index (TWI) normalised difference water (NDWI). Suitable weights for parameters are assigned according their relative importance association with storage based on pairwise comparison matrix (PCM). Four GWPZs respective coverages namely poor (3.39%), moderate (24.98%), good (33.36%) excellent (38.27%) categories found. central southern parts area covering portion Udalguri, Sonitpur Darrang districts Assam have porous geological settings floodplains, indicating high potentiality. In contrast, northern part hard rugged terrain lacks storage. Incorporating socio‐economic aspect, particularly number villages or without access suitable groundwater, significantly enhances study's utility. outcome cross‐verified well data obtained from Central Groundwater Board (CGWB) field which validated receiver operating characteristics (ROC) curve resulting an accuracy 72.9%. Hence, this inquiry implications both regional global significance will assist stakeholders authorities creating roadmap sustainable effective use.

Sustainable water resource management relies heavily on accurate groundwater potential mapping, especially in countries like Ethiopia, where is a primary drinking source. This study focuses the Maze-Zenti catchments, located Omo Basin of Ethiopia and covering an area 2,340 square kilometers, which are highly dependent resources. They aimed to identify zones using three advanced geospatial statistical methods: Multi-Influence Factor (MIF), Shannon Entropy (SE), Frequency Ratio (FR). These methods were selected for their demonstrated efficiency mapping. A comprehensive database was created, incorporating slope, elevation, drainage density, lithology, soil type, aspect, Topographic Wetness Index (TWI), lineament rainfall, land use. The results classified into four zones: low, moderate, high, very high across all models. ensemble model combining strong predictive capability, with 35.04% as 22.48% potential. Separately, frequency ratio (FR) emphasized (35.17%) (20.17%) zones, while entropy (SE) multi-influencing factor (MIF) models also identified significant portions moderate classes. Validation Receiver Operating Characteristic (ROC) curves established most reliable, achieving Area under Curve (AUC) 0.851, followed by (0.813) (0.784). numerical comparison actual well yields revealed 77.5% accuracy rate, further validating model's reliability. highlights critical role mapping regions limited resources offers flexible framework adaptable various hydrogeological conditions, making it valuable drillers, managers, researchers, other stakeholders management.
