Abstract

The work focuses on the hydrological modeling using the HEC-HMS tool of the hydrologicalmodeling. The HEC-HMS is the physical hydrological based model. For the pre-processing theArcGIS tool of hydrology is used for various data processing like fill sink, flow direction and flowaccumulation along with the delineation of the watershed of the Shivna River basin. The Shivna Riverbasin is located at 20.33° North and 75.19° East on the average elevation of 838 meter and it mergeto the Godavari river at the Jaiakwadi Reservoir. The Shivana River Basin play very important rolefor the reservoir planning and can be useful to understand the exact inflow of the river to thereservoir. The Shivna River is located in the semi-arid region and the rainfall is moderately lowwhich causes the less surface and subsurface water. Most of the agriculture is depend on the subsurfacewater and the growing demand of the water in the river basin is creating the water scarcity inthe Shivna River basin. After pre-processing the data, the map is created using the HEC-Geo HMSwhich makes the data suitable to run in HEC-HMS. The results show a good correlation between theobserved and the simulated data using the HEC-HMS.Keywords: HEC-HMS; Shivna River Basin; ArcGIS; HEC-GeoHMS
