Study on urban flood inundation analysis model for plain tidal river network region
摘要
Abstract
In order to carry out the urban flood inundation analysis of plain tidal river network region,the characteristics of the region,such as large density of rivers,special underlying surface,impact from municipal drainage on flood inundation,are comprehensively considered.From which,an unit model of river network drainage is proposed by taking the region confluently surrounded by main urban river,embankment,etc.as a generalized model for drainage is established by taking the sub-regions of drainage as the units according to their drainage capacities,which are coupled with the flood routing model for simulating main river channel,road and land surface,and then the urban flood inundation analysis model for plain tidal river network region is established.By taking Puxi Flood Control Protected Area of Shanghai as a case,the analysis on the flood inundation under the comprehensive impacts of the flood from the upstream river channel,storm tide,regional rainfall and the operation of the flood control project is carried out.The result shows that the hydrographs of the tidal (water) levels at Huangpu Park Hydrological Station,etc.are basically consistent with those observed data,while overflows occur at Suzhouhe,Dianpuhr,Xidaying Gang rivers,which are generally coincided with those from the actual conditions.The study result has a reference value for simulating the urban flood inundation of plain river network region.关键词
