In this study, two types of flume experiments were performed to investigate the momentum transport mechanisms and sediment deposition in the steady wake region behind a submerged vegetation patch. First, PIV measurements for vertical and horizontal planes were utilized to reveal the turbulence and secondary flow structures. Results of the velocity measurements show that the streamwise vegetation patch length affects the development processes of the vertical and horizontal mixing layers and the secondary flow structure. Second, the observation of sediment deposition indicated that fine sediment particles are stably deposited in the steady wake region where both the flow velocity and the turbulence intensity are small.
