The seaward sediments from Yangtze River triggered frequent and variable erosion and siltation of natural coast under conditions of the complex estuary geomorphology and hydrodynamic force, which brought negative influence on great coastal projects and became the main type of ecological disasters in the Shanghai area. This article together with results from monitoring data of sediment transport in the area of Yangtze River estuary analyzed its impact on deepwater channel project in Yangtze River Estuary, providing references for daily maintenance and safety operation of project.
