Abstract: The interactions of Rivers and the sea with each other in the estuarine areas perform complicated dynamic functions. A 1D and 2D coupling numerical algorithm is developed for simulation the flow and sediment transport in rivers and estuaries which based on the CC type finite volume frame and Roe type approximate Riemann solver. The 1D model is used to the long reaches of rivers and the 2D model based on the unstructured grid is used for the estuaries and sea. The flow and sediment transport of the Pearl Rivers and the delta estuary is implemented as an example to test the present algorithm. The numerical results comparison with measured data show that the model is correct, reliable and efficient.
