Abstract: We use satellite remote sensing and a DEM to determine the boundary of the Alaknanda basin. –watersheds are found in the Alaknanda Basin. Our detailed data on watershed areas over the area provide an important temporal assessment of water resource variability in this area. These data can be integrated into further studies to analyze morphometric analysis of the region and hence can be used for water resource management.
