For planning, designing and management of any water resources system, the study of the properties of river basin plays a significant role. Actually the life of any reservoir depends on sediment load of the river on which the basin is located. So to extend the life of the reservoir it is essential to study the drainage characteristics of the basin and the areas which contribute maximum sediments to the reservoir. Morphometric analysis gives the basic information about the drainage conditions, size and shape of the basin. In this study morphometric analysis has been carried out on Kulsi river basin using remote sensing and GIS. The study has been carried out for the area up to the dam site, as the sediment contribution to the reservoir is dominated by this area. From the analysis, it has been found that the basin is of 6th order and dendritic drainage pattern having elongated shape with less runoff and less prone to soil erosion. The whole watershed is divided into seven sub-watersheds (SWS 1-SWS 7) for prioritization, to determine the most erosion prone areas in the basin. Compound parameters have been estimated from areal, relief and shape parameters for prioritization of the sub-watersheds. The compound parameter value showed SWS 1 as the highest priority for land management and SWS 2 as the lowest priority. The priorities of watershed managements for the sub-basins are in the order of SWS 1, SWS 6, SWS 3, SWS 4, SWS 5, SWS 7 and SWS 2.
