The problem of numerical simulation of a possible flood in the area near the township of Shamaldy-Sai in the floodplain of the Naryn River, Kyrgyzstan within the framework of the OpenFOAM computational fluid dynamics package is considered in this paper. Modeling of a three-dimensional unsteady two-phase (water and air) flow is based on the complete Navier-Stokes-RANS equations supplemented with corresponding turbulence models. The position of the water–air interface was determined using the volume of fluid method - VOF.
