A Coupled Model of the 1D River Network and 3D Estuary Based on Hydrodynamics and Suspended Sediment Simulation

Figure 7

From Sixianjiao to Chaolianzhoutou, the annual amount of erosion and deposition in the sand excavation (up) and under the natural conditions (down) is provided in 1998. The comparison quantifies the impacts of the sand excavation in the bathymetry evolution and indicates that the amount of sand excavation has to be taken into account in the comparison between the observed and the modelled sediment erosion and deposition.
