Abstract: The numerical simulation of a flood flow with hydraulic jump was presented using the total variation diminishing (TVD) finite difference scheme based upon the Mac Cormack explicit method (TVD-Mac Cormack). The scheme was applied successfully to one-dimensional open-channel flow with hydraulic jump occurred at the transition in slope. The scheme was then extended to 2-D flow computation by introducing the method of time-splitting. The hydraulic jump taken place in a right-angle confluence due to a high velocity inflow from branch channel was simulated. For practical use, the proposed TVD-Mac Cormack scheme was expressed in generalized orthogonal coordinates. The simulation of the transonic flow caused by the transition in both slope and width of channel was carried out. The performance of the scheme was confirmed through comparison with experimental data.
