Characteristics of turbulent structure of open channel flow with flexible vegetation model on the bottom wall were investigated using velocity measurements and flow visualization techniques. The velocity measurements indicate that vertical and horizontal mean primary velocity shears(∂U/∂y,∂U/∂z) and maximums of turbulence intensity and vertical Reynolds shear stress are formed in the vicinity of the top of the flexible vegetation model. The results of flow visualization indicate that large scale streamwise vortex is formed over the vegetation model and a pair of vortex structure having vertical axis is formed behind of the vegetation model. The results of DPTV, which is combined dye injection method and Particle Tracking Velocimetry, show that the streamwise vortex contributes generating instantaneous Reynolds stress directly.
