Quasi-3D model and SDS (sub-depth scale) turbulence model are combined to simulate the horizontal shear layer development along the interface of bank vegetation. Turbulence productions caused by bottom friction and vegetation drag are formulated based on previous experiments on turbulence intensity in flows in an open channel and through model vegetation (cylinder arrays). Computations are made for two flow conditions of flume experiment with vegetation model published in literatures. Good agreements are obtained for transverse and streamwise velocity profiles in the developing shear layer containing horizontal coherent vortices. The characteristics of turbulence components are also predicted well. Furthermore, simulation results suggest that strong SDS turbulence is generated near vegetation boundary and transported to vegetation zone and main channel by horizontal coherent vortices.
