| Abstract: | In this essay the advantages and disadvantages of the combined solution of the 2-D estuary model and 1-D river network model have been analyzed.The idea in the elasticity that the consolidated bar and block are connected at the junction to calculate jointly with the finite element method,is used as a reference.The finite element combined solution is designed to realize the hydrodynamic solution integrating the river basin network model and estuary model.The application study proves that this method is logical and the calculated result is satisfactory. |
