The morphometric characteristics of the river basin are easily evaluated by using the integration of Remote Sensing (RS) and Geographic Information Systems (GIS). The benefits of this integration include saving time and effort as well as improving the accuracy of the analysis. Moreover, this technique is appropriate for describing the river basin and its streams. In this study, a detailed morphometric analysis of the Mula-Pravara River basin has been performed using the Cartosat-1 DEM. The performed morphometric analysis includes linear, areal, and relief aspects. The mean bifurcation ratio (Rb) value of the watershed is 7.615, which shows high overland flow and discharge due to the hilly nature of the terrain. The Mula-Pravara river basin has a drainage density (Dd) value of 0.52 km/km2 and falls in its lower category which indicates gentle slope terrain, medium-dense vegetation, and less permeability with medium precipitation. The stream frequency (SF) of the Mula-Pravara River basin is 0.39 numbers per km2, indicating poor runoff. The Mula-Pravara River basin has a length of overland flow (Lo) value of 0.965 indicating the influence of high structural disturbance, low permeability, and gentle slopes and moderate surface runoff. The Mula-Pravara River basin has a circularity ratio (Rc) value of 0.21. A low Rc value implies an elongated basin shape while a high Rc value indicates near circular. The elongation ratio (Re) of the Mula-Pravara River basin is 0.331. The Re values indicate an elongated basin shape with high relief and a gentle to steep slope. The Mula-Pravara River basin has a shape index value of 5.55. A higher shape index shows basin elongation and a weak flood discharge period.
