The evolution of the shore-normal profile shape of an accretional tidal flat is controlled by the transport of muddy and sandy sediments by tidal currents. To understand the evolution processes, a model is established to simulate the tidal flat profile changes in response to spring-neap tidal cycles, and it is applied to the accretional tidal flat on the central Jiangsu coast to investigate the interrelationships between the initial profile shape of the inter-tidal flat, tidal range, sediment supply, the equilibrium profile shape of the intertidal flat, and the long-term behavior of a prograding profile.
