Abstract

This study shows the effect of suspended load transport on calculated morphodynamic equilibria of tide-dominated ebb-tidal deltas. To make the formulation of the momentum equations and concentration equation consistent a spatially dependent friction coefficient in the formulation of the linearized bed shear stress is used. This resulting bottom patterns have a larger ebb-tidal delta and deeper channels. Furthermore, the ebbdominated channel has a more seaward extension and the delta is located further seaward. These results are more consistent with observations than the results obtained with a spatially uniform friction coefficient. First results of the model with suspended load sediment transport show that its main influence is that bottom patterns become more pronounced. The ebb-tidal delta contains more sediment, is more elongated in the alongshore direction and the channels are deeper. The effects of suspended load transport are more pronounced when the fall velocity is smaller.
