Simulation of Rainstorm Flood Based on SWMM Model ——Taking the New Campus of Zhengzhou University as an Example
With the increasing influence of climate change and human activities, the level of urbanization has been further improved, the urban area has been expanded rapidly, and the hydrological effect brought by urbanization has increased the frequency of flood disaster. In this paper, taking the new campus of Zhengzhou University as the research area, the SWMM model is used to simulate the rainstorm flood in different regions of the rainstorm recurrence period, the peak value, the degree of urbanization and the LID situation. The results show that the storm rainfall pattern has an important influence on the simulation results. The model can predict the drainage capacity of the drainage network and the simulation results in different scenarios.
