超标准洪水下吴江浦北地区河道行洪风险研究
Study on the risk of flood passage in river channel due to exceed standard flood within Pubei Region of Wujiang District
摘要
Abstract
Exceed standard floods are an important factor threatening water security in the plain river network area of the Taihu Lake Basin.By selecting the Pubei Region of Wujiang District as a typical case,a flood evolution model of the external river network of the study area was constructed to analyze the risk of overtopping the embankment when the water level exceeds the designed flood level and the peak flood level during the flood discharge in the study area under the condition of exceed standard floods in Taihu Lake.The results show that under the"99 actual situation"condition,the rivers in the main urban area of Wujiang generally exceed the designed water level;under the"99 southern"once-in-a-century condition,the water level of some sections along the Taipu River exceeds the designed flood level.The peak flood overtopping risk points on the east side of the Jiangnan Canal are more than those on the west side.When the Dongtaihu Gate is opened,the flood risk in the main urban area of Wujiang is relatively high.关键词
