Watershed management is a critical component of sustainable water resource planning and conservation. In the context of the Upper Beas Basin, a region of ecological and hydrological significance in the Indian Himalayas, this study presents an integrated approach for prioritizing sub-basin (SB) based on morphometric parameters and land use/land cover (LULC) analysis. The objective is to facilitate effective management and conservation efforts in a region highly susceptible to soil erosion using the analytical hierarchy process (AHP) technique. The present study used the CartoDEM (30 m) and Landsat image (30 m-year 2024) data for basin morphometry and LULC analysis of the study area, respectively. Based on morphometry and LULC, eight sub-basins (SB26, SB9, SB14, SB6, SB11, SB22, SB10, and SB18) of the upper Beas basin are in a very high-priority zone. As climate variability and land use change continue to exert pressure on fragile Himalayan ecosystems, this study serves as a valuable tool for policymakers and researchers engaged in watershed management and sustainable development efforts in similar mountainous regions worldwide.
