ABSTRACT Watershed degradation is a significant global problem, and as mountainous nation, Nepal faces even greater challenges in managing its water resources. Because it largely unrealistic to execute management plans at time for large spatial extent, subwatershed prioritization has now become promising approach watersheds. Our study delineated prioritize subwatersheds the Gandaki Province, Nepal, utilizing geospatial technique‐based morphometric analysis first provincial level. Using Digital Elevation Model having 30‐m resolution ArcGIS, we 121 across province, ranging size from 29 796 km 2 . Subwatersheds were quantitatively ranked by assigning 60% weight biophysical parameters 40% anthropogenic factors. The study's novel inclusion of road network density livestock within aspect, each assigned 10 points, alongside population that received 20 points. Eleven subwatersheds, one district, prioritized because highest risk. Myagdi Khola 3 covering an area 309 , Kali Nadi 1 Parbat 33 two with score 100. scoring higher priorities should be adopted development programs immediate effect. This directly contributes Sustainable Development Goals promoting targeted action resource management, supporting ecosystem preservation, climate resilience.
