TAILIEUCHUNG - Preparation of curve number map for hydrologic simulation using GIS and HEC-Geo-HMS model

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 ( Km2 ) of upper Hasdeosubbasin, by implementing three software’s . Arc View GIS with Arc Info, Arc Hydro Tool and Geospatial Hydrologic Modeling Extension (HEC-Geo HMS version ) model for Arc View GIS . 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. | Preparation of curve number map for hydrologic simulation using GIS and HEC-Geo-HMS model
