基于SWMM的城市暴雨内涝风险分析
Risk analysis of urban storm waterlogging based on SWMM:a case study of Yaohu Campus of Nanchang Institute of Technology
摘要
Abstract
To solve the urban flooding problem,a storm flood management model was constructed based on SWMM with Yao-hu Campus of Nanchang Institute of Technology used as the study area to simulate the spatial distribution of inundation du-ration and the spatial distribution of waterlogging depth in the study area under different recurrence period storm process ca-ses,and the risk zoning of storm flooding in the study area was carried out by combining the elevation distribution.The re-sults show that the simulation results of the SWMM model are close to the measured results,and the simulation effect is good;with the increase of the rainstorm recurrence period,the inundation time and water depth in the region increased.The area of the medium-high risk area of waterlogging in the 50-year rainstorm increased by 12.51%compared with that in the 5-year rainstorm,and the area of the second-high risk area increased by 9.94%,while the increase of the high-risk area was small.The results can provide reference for the construction of sponge city.关键词
