Geospatial Assessment and Watershed Prioritization of the Koyna River Basin Using Morphometric Analysis and Pca

In order to evaluate the linear, areal, and relief characteristics of channel basins, morphometric encompasses the quantitative measurement along with evaluation of earth surface structure, particularly the size and form of land. Watershed prioritization, ranks watersheds according to the order in which they ought to be treated. The Koyna River in Satara, Maharashtra, India, an area of 1938 km ² , was subject of the current analysis. The basin has the sixth-highest order (main stem). With an average Rb value of 4.19, the watershed was categorized as homogeneous, showing little structural disturbance and devoid of hilly or cleft features. With a coarse drainage pattern and a low drainage density, the drainage density ranges from 0.98 to 1.2336. Furthermore, the basin's circulatory ratio and form factor, which exhibit an elongated shape, range from 0.1764 to 0.3079 and 31996 to 6.641, respectively. The relief ratio, which ranges from 0.0092 to 0.032, suggest that there is barely erosion. Out of seven sub-watersheds, SW1 was ranked seventh in terms of priority, while SW3 was ranked first. The acquired results from the morphometric analysis of the watershed are advantageous for area's water resource management.
