Abstract
In this paper performance of the SSIIM2 model (3D finite-volume model with the k-ε-type turbulence model closure) in confluence hydrodynamics modelling is assessed using the published experimental data and the author’s field data. It is shown that the transfer of momentum from the tributary to the main channel and variations of the recirculation zone width are modeled satisfactorily, and that the shape of the velocity profiles in the post-confluence channel is captured well. However, velocity magnitudes are underestimated, especially that of the vertical velocity. This may be attributed to the fact that the model is based on the assumption of the hydrostatic pressure distribution, which is not satisfied at the confluence.
