| Abstract: |
| In this paper,the ENO scheme and the Runge-Kutta time discertization method were applied to the one-dimensional Saint-Venant water equations for numerical simulation of dam-break flows,and the water depth and the velocity along the distance were obtained.The computed results have no numerical oscillatory at the discontinuity.Comparisons of the computed results and analytical solutions are in agreement,which show that the ENO scheme is a new high-resolution and non-oscillatory differential scheme,and that the high-resolution model based on the ENO scheme can effectively simulate the dam-break flows. |
