摘　　要：Flood discharge over top outlet of dam is simulated by 2 dimension water air two phase mathematical model. Distribution of dynamic pressure, turbulent kinetic energy (k), turbulent dissipation rate (ε), free water surface and velocity field have been obtained. The simulated results were tested by physical model, which shows that the computed results are identical with that of the physical model.Flood discharge over top outlet of dam is simulated by 2 dimension water air two phase mathematical model.
