|Abstract:||Present study used a three-dimensional numerical model of multi-fraction sediment transport based on the coupling of a modified code model of environmental fluid dynamics and a model simulating nearshore waves to predict the estuarine morphological changes under the combined action of wind, waves, and current. Wave-current interaction played a remarkable role in increasing the sediment concentration. Distribution of the sediment concentration is better simulated and agreed with the measured data when using the coupled model compared to only considering the currents. Morphological changes predicted by the coupled model are basically coincident with the measured topographic map, and the model’s error is within plus or minus 10 percentage points.|
