Flood Modelling and Risk Analysis of Cinan Feizuo Flood Protection Area, Huaihe River Basin

This study evaluated multiple aspects of flood risks and effects on the Cinan Feizuo protection area in Huaihe River basin. Flooding remains a leading problem for infrastructure, especially urban, residential areas region. Effective modeling urbanized floodplains is challenging, but MIKE (ID-2D) paramount analyzing quantifying risk vulnerable The Saint-Venant equation one-dimensional (1D) 11 model were used to understand dynamics River, two-dimensional (2D) 21 was applied assess area. finite volume method (FVM) discrete grid problems, models coupled through weir find flow from 1D domain 2D investigate water level changes. Flood inundation maps generated maximum discharge, velocity, submerged depth 50- 100-year events assessed with risk. Chenbei indicated high 50 100 years which exceeds inundates minimum time. Conversely, comparatively higher than 50-year flood, lower time step. analysis identified significant damage caused by over target regions. findings this provide technical support loss assessment within have important reference values regional control, disaster reduction decision making, constructive planning.
