Dam Break Flood Simulation For Maithon And Panchet Dams Using Nws Dambrk Model And Inundation Mapping

摘要

Dam break flood simulation of two dams, namely, Panchet and Maithon located on Damodar and Barakar, respectively, river have been performed using NWS DAMBRK model. The. failure of Maithon dam has been simulated and its outflow at the confluence of the two rivers has been considered as lateral inflow, while simulating the failure for Panchet dam over river Damodar. The failure of two dams are simulated under their probable maximum flood (PMF) condition. The maximum discharge, maximum stage and maximum flow velocity and its time of occurrence at various cross-sections along the Damodar and Barakar rivers have been computed. The inundation maps showing the extent, depth and area of inundation have been prepared using GIS software.
