  Abstract


For any hydrological modeling, delineation of watershed details like drainage network and catchment area extraction are very important. It is of great need to delineate the catchment area in the form of sub watershed areas to find out the characteristics easily. It is possible to develop using geospatial technologies due to temporal and spatial variations. Automatic delineation of watershed is time consuming when compare to manual method. With the development of Geospatial technology, automatic extraction of watershed details became very popular. Digital Elevation Model (DEM) data can be considered as input data to delineate catchment area and drainage network using GIS. ArcHydro is an add-on tool in ArcGIS software, which plays a vital role in building any hydrological information system for the support of hydrologic modeling in water resources development. In ArcHydro model, there are many sequential dropdown tools available, which are to be properly followed in order to delineate watershed for the management of water resources. Hence, a comprehensive geospatial model has been developed in Model Builder of ArcGIS software to run the model at a time to complete the process to extract the features like drainage network and catchment area from ArcHydro tool. In the present research, Nandyal area is selected to delineate catchment area and drainage network. 30m DEM data was used for delineation of watershed as input data. The major functions of ArcHydro tool are Flow Direction, Flow Accumulation and determining watershed and extraction of drainage lines.
