Numerical Simulation of Dam-break Flood Based on HEC-RAS Software
In this paper,HEC-RAS software is used for dam-break flood simulation analysis,using the latest HEC-RAS 6.1,the operation flow of the software in the process of dam-break flood,such as terrain generation,reservoir modeling,parameter input,boundary condition generation,calculation and post-treatment,is introduced in detail.The result of calculation can get the submerged water depth map and water depth process line of the corresponding area,and then get the influence area of dam break,and provide the relevant reference for the decision-making department,the research method can provide reference for similar dam-break flood simulation research in the future.
