摘要：

Two-dimensional flood waves resulting from the instantaneous break of dams are numerically examined. The governing system of differential equations is transformed into an equivalent system applied over a square-grid network in order to overcome the difficulties and inaccuracies associated with the determination of flow characteristics near the flow boundaries. The McCormack two-step, predictor-corrector, scheme is used for the solution of the transformed system of equations. Comparisons between computed and experimental data show a satisfactory agreement.
