We explore the effects of land reclamation on the morphological evolution and the sediment sorting on a tidal flat using a state-of-the-art numerical model. The results indicate that the longitudinal profile adjusts itself converging to new equilibrium states after a series of reclamations. Relatively fine sediments deposit adjacent to the sea dike, which is related to the tide-dominate hydrodynamics. Moreover, the amount of sediment deposition in front of the dike peaks, when the dike is located where the bed surface is at MSL.
