In this paper, the movement of the water surface with macroscopic particles during a dam break flow using the volume of fluid (VOF) methods, the discrete phase model (DPM) and macroscopic particle model (MPM) models were numerically simulated. To solve this equation system numerically, the PISO numerical algorithm was chosen. The accuracy of the 3D model and the selected numerical scheme were tested using some laboratory measurements on the destruction of the dam break problem. In the test problem, the values were matched with measurement values and simulation data of other authors. Furthermore, two problems were also considered, the first problem is dam break flow with macroscopic particles, and the second problem–water movement with macroscopic particles, through a heterogeneous terrain and a dam that has a hole. With the help of the problems, the flooding zones and the time of flooding evacuating people from dangerous areas were determined.
