- Abstract
Dam-break flood seriously threatens people lives and properties in the downstream areas and therefore, it is of great importance to accurately predict the inundation area. A high-resolution two-dimensional shallow water hydrodynamic model was applied to model floods downstream of the Chushandian Reservoir and the flood disaster risk index was adopted to quantify the disaster degree. The model resolved the hydraulic characteristics of floods as well as the variations of inundation area and disaster degree downstream for different dam-break scenarios. The numerical predictions demonstrate that the increase of inundation area in the initial stage is mainly determined by the peak discharge, while the final inundation area is dependent on the water volume released from the reservoir. The present work underpins the design of flood defense plan of Chushandian Reservoir.
