dc.description.abstract | Watershed prioritization has gained importance in natural resource management, especially watershed management. Kosi watershed is a constituent of the Kosi river, and it falls within the Almora and Nainital districts of the Uttarakhand, covering an 1819 km2 area. Using remote sensing and GIS application, prioritization of Kosi sub-watersheds have been done based on different morphological attribute lineage with soil erodibility and land use and land cover analysis. Prioritization has been performed to identify environmental stress areas. ArcGis 10.4.1 has been utilized for watershed delineation, morphometric analysis, and LULC supervised classification. The Kosi watershed is further delineated into 17 sub-watersheds for prioritization purposes. Various morphometric parameters (linear, areal, and relief) have been determined for each sub-watershed. Nine morphometric parameters has been selected for pairwise comparison matrix for prioritization based on the FAHP technique then suitable weights are assigned to the morphometric parameters. Further, these weights has normalized to assign final ranks to the sub-watersheds. Subwatersheds have been classified into five categories: very low, low, moderate, high, and very high. . In FAHP technique only Sub-watersheds SW1 and SW3 are found very high priority, whereas sub-watersheds SW8 and SW11 comes under very less priority. Land use and land cover mapping have been carried out with the help of Landsat 8 LISS III level II data with an overall accuracy of 84.98 % and a kappa coefficient of 0.81. Kosi watershed is classified into six classes forest, wasteland, waterbody, cultivated land, rocks and built-up area. Three classes wasteland, cultivated land, forest area are considered for prioritization, an average of the individual rank are determined for the final ranking of the sub-watersheds. Based on LULC sub-watersheds SW3, SW6 and SW9 comes under very high priority, and sub-watersheds SW14 and SW17 comes under very less priority. | en_US |
