By numerical simulation of the phenomenon of failure of dams and the flow of their flow, it is possible to design more precisely the structures and their location. The purpose of this study was to investigate the wave propagation phenomenon due to the failure of the rocky mortar-watering dam in the Marivan sub-basin of Zarivar in two-dimensional and three-dimensional models using the Fluent model. The results showed that the k-ε Standard model, with the lowest RMSE value, has more accuracy in simulation. Also, the study of the diffusion of flood damages in muddy water shows that the wave formed as a jet of sharp and daggle shapes downwards and the velocity of the forehead in muddy mud is much higher than water There is no contamination of the mud, which is due to the formation of the shape of the aerodynamics of the forehead in muddy mud, which causes more flow velocity due to the failure of damaged dams and can lead to further destruction of the bottom dams of the watershed. The results showed that the fl ouent model has an acceptable accuracy and ability to simulate dam failure in both wet and dry substrate conditions.
