摘要

With the rapidly declining water resources, global attention converges on securing water access, underscored by international conventions such as the Ramsar Convention on Wetlands. The growing demand for freshwater reflects the impacts of population expansion, economic development, and climate warming. This necessitates proactive and effective water resource management. The present study is centered on prioritizing the Chambal River sub-basins using remote sensing and GIS-based techniques for effective water resource management. The prioritization relies on a comprehensive analysis of hydrological-based morphometric parameters and Land Use Land Cover (LULC) changes, assigning ranks and Compound Factor Values (CFV) method to sub-basins. Morphometric analysis reveals dendritic to parallel drainage patterns with moderate relief across all Chambal River sub-basins. LULC change analysis indicates significant increases in built-up, agricultural, and waterbody areas, reflecting heightened biotic pressure. Conversely, notable decreases are observed in Wasteland and Degraded/scrub forest regions. Prioritization identifies sub-basin 7 (Lower Chambal basin) as the highest priority with the lowest CFV (3.27), emphasizing its ecological significance. It encompasses the National Chambal Sanctuary (NCS), Kuno National Park, Kailadevi Wildlife Sanctuary, and Chambal badlands, and it is also susceptible to soil erosion. The soil and water conservation measures need to be taken for sustainable management of the area. This research offers crucial insights for policymakers and planners engaged in water resource management, guiding sustainable initiatives.
