The qualitative and quantitative analysis of the numerical simulation results for one- and two-dimensional laboratory experiments have shown that the MacCormack numerical scheme yields physically plausible results, and can be efficiently used in solving dam-break problems for which a simulation with limited numerical diffusion is required. The wave celerity and the water depth predictions, made by this computational scheme, for one-dimensional dam-break flows, agree well with the results of the laboratory measurements, as it was reported by other investigators. The wave front advancing depends, during the initial phase of the two-dimensional numerical simulation, on the imposed initial condition at the dam cross-section. However, the influence of the applied initial condition rapidly decreases in time. The water level differences between the computed and the measured values are within acceptable limits. Additional validation of the two-dimensional model against field data would be valuable.
