Abstract
The accurate measurement of geomorphometric parameters is crucial for assessing the condition of watersheds, particularly in mountain ecosystems and extensive areas where it can be challenging to obtain precise measurements. In this study, drainage density was used to evaluate soil erosion in the Sarbari Khud watershed located in the lesser Himalayan region of Himachal Pradesh, India, using Geographical Information System (GIS) and remotely sensed digital data. The analysis of drainage density indicated that the Sarbari Khud watershed is susceptible to surface erosion and soil degradation. The watershed was classified into low, moderate, severe, and very severe erosion categories based on the drainage density values, which revealed that about 50 percent of the area suffers from very severe erosion. The findings of this study suggest that drainage density can be used as an effective indicator for estimating erosion status of watersheds. This information can be used to prioritize watershed areas for soil and water conservation measures, which are critical for ensuring the sustainability of the watershed. Overall, this research work highlights the significance of using GIS and remotely sensed data along with direct survey-based topographical maps for assessing soil erosion in mountain ecosystems and extensive areas. The results of this study can be used to guide conservation efforts and inform policy decisions aimed at mitigating the negative impacts of soil erosion on the environment and local communities.
