Abstract

As global warming urbanization process accelerated, urban waterlogging problem is increasingly serious, has become the research hotspot nowadays. City rainstorm waterlogging scene simulation is one of the important link in the research of the process in which residents shelter when city rainstorm waterlogging occurred. To develop urban rainstorm product scenario simulation study can guide us to determine the product elimination and influence range and location. This study using a one-dimensional and two-dimensional unsteady flow as the basic equation, with irregular grid as the basic frame, build urban rainstorm waterlogging deposition numerical simulation model, combining with the information diffusion theory calculation rainstorm probabilities in the study area, on this basis, set the study area rainstorm waterlogging situation, realized the different waterlogging scene simulation and visualization. The results show that the heavy rain that just sccumulate waterlogging disasters occurs once every five years in the study area, and depth of 0-0.47m,velocity between 0-0.43m/s.there is the biggest produce waterlogging which sccumulate with the heavy rain occurs once every 100 years, and the depth of 0-3m,velocity between 3-3.4m/s.
