摘要
沿海地区河流常常直接入海,其河口段水位多受上游洪水、河口潮水共同影响,这在一定程度上增加了河口段堤防整治工程设计的工作难度。以沿海地区——南渡江河口为例,基于考虑上游松涛、迈湾2座大型水库调蓄影响后的龙塘站设计洪水、海口站设计高潮位,分别分析了以洪水为主、以潮水为主时的河口洪潮遭遇情况,可为南渡江河口段河道防洪整治工作提供一定的设计参考依据。
Rivers in coastal areas often flow directly into the sea.In certain estuary sections,water levels are greatly affected by upstream water supply and tides at the river mouth,which increases the difficulty of designing embankment projects for the estuary section.Taking the estuary of the Nandu River in the coastal area as an example,this article analyzes the encounter of flood and tide in the estuary under two scenarios:flood as the main factor and tide as the main factor,based on the design flood of the Longtan Station and the design high tide level of the Haikou Station,which have been adjusted for the impact of the Songtao and Maiwan Reservoirs upstream.This can provide a certain design reference basis for flood control and training work in the estuary section of the Nandu River.
