Morphology change at tidal influent estuary is controlled by the net sediment transport rate of river and tidal transport, and variations in features (bathymetry, structures, etc.) where scour and shoaling take place. To examine river and tidal exchange sediment transport in a systematic way, we investigated sediment transportation at the Bach Dang estuary with a coupled tide, wave and sediment transport-morphology change numerical modeling system. Five simulations consisting of
