Abstract: Abstract In this study, a method based on the Navier-Stokes equation was developed to simulate the dam break flow. The free surface movement of water is carried out using the Newtonian fluid model, and the mud impurity movement is performed by the model of non-Newtonian fluid based on the volume of fluid (VOF) method. In order to minimize the fluctuations of the free surface near a moving front, the VOF method was used. The numerical Pressure-Implicit with Splitting of Operators (PISO) algorithm was chosen as a numerical method for solving equations. The developed model is verified with a wide range of measurement results and with the computational data of other authors. Good computational data were obtained from flood forecasting resulting from the instantaneous collapse of the dam. It has been demonstrated that this model is well balanced and reliable, and can accurately record the movement of dam break in difficult terrain. With the help of the proposed model, the Mynzhylky dam break flow was modeled.
