The Nileswar sub-watershed in the Kasaragod district, located in Northern Kerala, underwent an analysis as part of planning watershed management activities. Geospatial tools, including remote sensing and GIS, have been employed to delineate watershed boundaries and derive stream networks. The Shuttle Radar Topographic Mission (SRTM) Digital Elevation Model (DEM) data was utilized for morphometric analysis, which involved the evaluation of various morphometric parameters like linear characteristics, areal properties, and relief features. These morphometric parameters were examined using established methods such as those pioneered by Horton and Strahler. To facilitate this, micro-watersheds were defined using the DEM data using ArcGIS software. An array of watershed parameters, including stream order, stream length, stream frequency, drainage density, slope, bifurcation ratio, form factor, circulatory ratio, elongation ratio, and infiltration number, were computed individually for each of the nine micro-watersheds through geospatial techniques. The sub-watershed was identified as fifth order stream. The compound scores were calculated from these morphometric parameters based on the compound ranking procedure. Based on their prioritized scores, the micro-watersheds were categorized into three classes: high (<4.7), medium (4.7–5.3), and low (>5.3) priority. In this study, micro-watershed 6 has been identified as a high-priority area requiring urgent soil conservation measures.
