Watershed Morphometry provides the base to understand the hydrological behaviour, landscape evolution and environmental sustainability. Quantitative analysis of basin geometry is crucial for understanding runoff characteristics, erosion intensity and water resource availability, all of which directly influence environmental stability and sustainable watershed management. This study presents a Morphometric assessment of the Khandepar River basin, a tributary of the Mandovi river, using Remote Sensing (RS) and Geographic Information System (GIS) techniques. Basin boundaries are defined using topographical maps and ASTER DEM (2011) data. Survey of India toposheet no D43C3(48I/3) were used as a base map to extract drainage networks using Strahler’s Method (1952) and compute linear, areal and relief morphometric parameters. A total of twenty-six morphometric indices were analyzed to evaluate basin shape, drainage efficiency and terrain characteristics using QGIS 3.14 software and MS Excel. The elongation ratio, form factor and circularity ratio indicate an elongated basin configuration, suggesting moderate runoff response and lower peak flood potential. Hypsometric analysis reveals varying stages of erosional activity, highlighting areas susceptible to moderate soil erosion and land degradation. The findings emphasize the role of morphometric analysis as an effective tool for identifying environmentally sensitive zones and supporting sustainable watershed planning and soil and water conservation strategies.
