Abstract:

According to the requirement of mountain flood prevention project,we conducted research on flood impact and inundation of urban area.Baokang county in Hubei Province was selected as a typical mountainous county for case study.Through field investigation and data collection,we designed flood calculation schemes,and built hydrodynamics model,flood routing model and flood inundation model.The calculation results reveal that the method has good theoretical basis,fast calculation speed and accurate calculation results.Moreover,two-dimensional model nesting and rational and reliable flood impact analysis are carried out in this paper.The research results can provide valuable reference for flood control decision-making departments.

Key words: flood routing, risk analysis, hydrogynamics model, inundation area, flood prevention standard
