The study is carried out with a purpose to apply various techniques and models for the delineation of catchment and developing methods in order to calculate the Curve Numbers for the Manendragarh watershed (1023.96 Km2) of upper Hasdeosubbasin, by implementing three software’s i.e. Arc View GIS 10.4 with Arc Info, Arc Hydro Tool and Geospatial Hydrologic Modeling Extension (HEC-Geo HMS version 10.3) model for Arc View GIS 10.3. Multi layers like soil layer, DEM and Land Use Land Cover layer was combined and CN grid map was prepared. In particular, SCS-CN (Soil Conservation Curve Number) is a model through which the estimation of the direct runoff can be achieved. This method comprises numerous important properties of the watershed such as Hydrological Soil Groups and land use, which will use as an input for various hydrological model.

Keywords: GIS, Curve number(CN), Hydrologic models, HEC-Geo-HMS, Land use, watershed planning
