摘要：Baimao shoal is the key barrier in the project of 12.5m deep-water channel of the Yangtze estuary extending upward to Nanjing. Meanwhile a large number of wetlands locate along the riverbank of Baimao shoal North waterway. It is important to develop an analysis about the hydrodynamic influence by regulation project as well as by the impact of terrible typhoons around Baimao shoal. In this study, a 2-D numerical model was employed and verified with observed datasets. The hydrodynamic conditions on Baimao shoal section under the impact of Typhoon Winnie were simulated. Influences from channel regulating structures towards water level and flow velocity under the typhoon were also analyzed by the numerical model. It shows that regulation project has smaller impact towards hydrodynamic condition on Baimao shoal section. While, typhoon Winnie may cause water level and flow velocity increase by a large margin at wetland area and groin head. The significant increases of water level and flow velocity induced by typhoon need to be considered properly.
