Abstract EN
River networks and estuaries are very common in coastal areas.
Runoff from the upper stream interacts with tidal current from open sea in these two systems, leading to a complex hydrodynamics process.
Therefore, it is necessary to consider the two systems as a whole to study the flow and suspended sediment transport.
Firstly, a 1D model is established in the Pearl River network and a 3D model is applied in its estuary.
As sufficient mass exchanges between the river network and its estuary, a strict mathematical relationship of water level at the interfaces can be adopted to couple the 1D model with the 3D model.
By doing so, the coupled model does not need to have common nested grids.
The river network exchanges the suspended sediment with its estuary by adding the continuity conditions at the interfaces.
The coupled model is, respectively, calibrated in the dry season and the wet season.
The results demonstrate that the coupled model works excellently in simulating water level and discharge.
Although there are more errors in simulating suspended sediment concentration due to some reasons, the coupled model is still good enough to evaluate the suspended sediment transport in river network and estuary systems.
