چکیده:

In this paper Time Splitting Projection Method (TSPM) is applied to solve the governing equations of unsteady flow in open channel using explicit and implicit techniques. For modelling flow in river network Double Sweep Method (DSM) is implemented. The proposed model is validated by comparing the numerical results with some benchmark analytical examples and with the results of Mike 11 commercial software. Comparisons reveal that proper results can be achieved implementing TSPM and without using high order accurate techniques. Besides, the proposed method possesses acceptable execution time in comparison with other methods.
