摘要：
In this research, a numerical investigation is carried out on the effect of obstacle presence on the water flow during the dam-break in a dry bed. The validity of the numerical simulations is confirmed after comparing the results with the experimental evidences. Rectangular, trapezoidal and triangle obstacles are simulated numerically to explain the obstacle effect on the water flow. Water surface tracking and turbulent flow are modelled using Volume of Fluid (VOF) method and the standard k-omega model, respectively. Pressure and velocity variations during the dam-break flow are presented and analyzed.
