A state-of-the-art morphodynamic model was used to explore the effects of bathymetric perturbation on the morphodynamic modeling of parallel tidal channels. Preliminary results indicate that there exists a critical range of the magnitude of initial perturbation, within which the morphodynamic development tends to be similar. Comparing with the tidal flats without initial perturbation, a slight increase in perturbation magnitude can considerably enhance the morphodynamic development. However perturbation with a magnitude beyond the critical range will lead to a notably distinctive pattern. Channel-flat morphology is also influenced by perturbation distribution. Sparser distribution of initial perturbaion could induce sparser tidal channels.
