Abstract:
The described study of the Morphometric analysis based on several drainage parameters, by which the watershed streams have been classified up to fifth order streams of Pravara River Basin, Maharashtra using GIS and Remote Sensing technique. Topographical maps and ASTER DEM data at 30m spatial resolution have been used for the analysis. Stream networks, different linear, areal, and relief aspects of the basin were analyzed using QGIS 3.16 software. The linear aspects of watershed was carried out i.e., Stream order (625), Bifurcation ratio (6.24), Stream length (1873Km) and aerial aspects such as Drainage density (D_d = 0.71), Stream frequency ( F_s=0.24), Form factor ( F_f = 0.10), Circulatory ratio ( R_c = 0.13) and Elongation ratio (R_e=0.36) has been carried out on the basis of soil erosion. The study of the data revealed that the total no of streams were 625 in that 475.00 in first order, 117.00 in second, 30.00 in third, 2.0 in fourth and 1.0 in fifth simultaneously. The low Bifurcation ratio ( R_b ) value reveals that a lower peak flow would result from the watershed and it can be more risk of flooding. The low Drainage density (D_d) value indicates that the basin has moderately low permeable soil (Black soil) and sparse vegetative cover. The low Circulatory ratio ( R_c ) value also indicates as the watershed basin is almost elongated in shape, it has a high discharge rate of runoff and poorly permeable soil condition.
