Abstract

The Nanhui tidal flat (NTF), located at the junction of Yangtze River Estuary and Hangzhou Bay, is influenced by two tidal currents in these areas. In recent years, the geomorphology, water and sediment migration, and deposition at the flat have significantly changed because of the deposition promotion of low beach reclamation projects. In this study, the recent topographical evolution of NTF is analyzed. The results showed that the seasonal variation of the NTF is mainly caused by wading reclamation projects surrounding the NTF and the specific depositional dynamic environment of water-sediment exchange in swales. Distinct seasonal differences in erosion and siltation at the NTF are also observed.
