Frequent floods and soil erosion have become a threat to food security by reduction in richness of soil, due to more water flowing over land causing watershed soil erosion. Hence, an effective watershed conservation strategy must be developed to deal with it. The central focus of this research is the morphometric analysis and evaluation of the Hypsometric curve of the watershed area of Bhagirathi River basin (the study area) which was conducted using geospatial tools in ArcMap and Digital Elevation Model (DEM) data. The research demonstrates to analyse a variety of morphometric statistics to understand the basin’s features. The basin’s overall drainage area was measured to be 9876.24 km2, with a dendritic drainage pattern characterized by 1310 streams spanning a length of 7520.93 km. The hypsometric curve analysed in the study revealed that the basin is in a state of equilibrium or maturity and is prone to soil erosion, as evidenced by a hypsometric integral (Hi) value of 0.49. In order to manage the basin sustainably with respect to soil erosion, identification and management of key factors/variables based on this data is crucial. GIS and remote sensing tools were used to assess results from morphometry with hypsometry and its impact on basin’s water and soil.
