Abstract
Identification, classification, and monitoring of the earth resources along with detailed topographic information for use in hydrological analysis and modelling can be easily done by using remote sensing. Present study was conducted for selection of watershed outlet, developing the watershed boundary, clipping the watershed from the entire basin and the streamline generation for Torsa river watersheds from SRTM data. Using the ERDAS IMAGINE 8.6 and ArcGIS 9.2 software the delineation was done. A total number of 163959 sinks were found to be present in the DEM data, after sink filling the numbers of sinks were reduced to 6225 that gave continuous stream network. The Torsa river watersheds boundaries were generated from the filled DEM data. Watershed catchment was delineated by superimposing this clipped stream network over watershed boundary image. Satellite imageries, soil data, land use, land cover map etc. can be generated to develop a detailed database for quick reference of the hydrologists working in the region
