N2 - This paper presents a Reynolds stress modeling of compound open-channel flows with vegetation on the floodplain. In the Reynolds stress model, we use the SSG model by Speziale et al. (1991) for pressure-strain correlation term, Mellor and Herring's (1973) model for the turbulent diffusion term, and Hanjalic and Launder's (1972) model for the dissipation term. In order to take into account the anisotropy of turbulence due to the free surface, the combination of Shir's (1973) model and Gibson and Launder's (1978) model is included in the pressure-strain correlation model. Model validations are carried out for the compound open-channel flows without vegetation. Then, the model is applied to the compound open-channel flows with vegetated floodplains. The mean flow and turbulence structures are simulated and the impact of vegetation on the floodplains is investigated.
