Spillways are structures used for releasing the surplus floodwater in necessary conditions from
storage dams. Side spillway is one of the most common and complicated structures. In this research,
hydraulics of the flow in the physical model of flood control structure for Vanyar dam which
consists of side spillway, lavok, transition, ogee spillway and chute is three dimensionally
simulated, using fluent numerical model and the results consisting of flow depth and hydrostatic
pressure at 110 points were compared with experimental data. For flow analysis, k-ε model for
turbulence and volume of fluid (VOF) model for multiphase flow simulation were applied. The
analysis of turbulence parameters in lavok channel and boundary layer development on chute was
also provided. Results show that there is a good agreement between numerical and experimental
results, especially standard k-ε model for hydrostatic pressure and RNG k-ε model for water surface
profile.
