Abstract: Surface analysis was carried out in a micro-watershed of Telbal district Srinagar (J&K) using Digital Elevation Models. The study area is located between longitudes 74°50'36"E to 74°54'30"E and latitudes 34°8'7 "N to 34°9'58"N covering an area of 1090.75 hectares. Boundary of the study area was first delineated and geo-referenced in GIS environment. After geo-referencing, rectification was done with Linear Imaging Self Scanning Sensors image (LISS-IV data). Surface analysis in the form of the contour, slope, aspect and hill shade maps were generated in Arc map 10.2. Most of the study area lies in the slope range of 0-5% comprising 47.50% of the total area, 30.92% was observed to be nearly gentle slopping and 19.52% under very gentle to strong slopping. The 20 meter contour lines showed that the lowest elevation was 1580m above mean sea level and highest elevation was 2560m amsl. The maximum area faces towards northwest aspect which is about 23.43% of the total area and are steeper as compared to other areas and about 17.96% of the total area is facing towards north direction. Study area followed dendritic drainage pattern and 13 land uses were classified. The parameters generated can be considered as an important inputs for GIS-based decision support system for scientific land use planning of the watershed and can generate various outputs like land capability classification, soil suitability classification and other conservation plans for the area.
