Runoff volume model for Godavari sub-basin using HEC-RAS software

This study contains Runoff Model which integrates GIS and the hydrological model. HEC-RAS software was used to simulate rainfall volume and create a model result in Kaleshwaram Watershed, Telangana, India. The Watershed delineation has considered Maneru Dam, proposed Tummadihatty Barrage on Pranahita River. The Medigadda Barrage has coordinates 18° 42ʹ 56ʹʹ N 80° 04ʹ 33ʹʹ E have been considered for the estimation of floodwater and runoff volume. The study area has Catchment No. 313, Godavari sub-basin. (Telangana state India). The Digital model results from the simulation were compared with the observed water storage data for the storms that occurred during the monsoon season for the year 2020. The Digital model (DEM) results will benefit the future forecast of flood volume and estimate runoff in Medigadda Barrage. During rainfall and run-off, volume simulation can identify the streamlines according to the topography, flow velocity, depth, and volume of water. Rain data of 141 stations within 22,670 Sq.km have taken to understand rainfall patterns and Rainfall-Runoff simulations. The velocity, depth and volume flow has observed for the given simulation as 5.3 m/s, 20 m and 26000m3 respectively. In this paper, it is limited for the one simulation run for the year 2020 to avoid the more accumulation of data and confusion.
