Free Surface Simulations for a Removable Spillway Weir
The flow field around a removable spillway weir structure (RSW) at Little Goose Dam is numerically predicted. The modeling approach and main characteristic of the CFD model used in this study are presented. The model is based on the Reynolds-Averaged Navier-Stokes (RANS) equations, with a standard κ - ε turbulence model. The Volume of Fluid (VOF) method is used to predict the discharge for a given forebay elevation. The model is used to evaluate the possible reduction of the spillway capacity during a Probably Maximum Flood (PMF) event. Flow field characteristics with and without the RSW structure are presented and discussed. The hydraulic force on the RSW structure is calculated.
