• Visualization of Turbulent Structure in Open-channel Flow with Vegetated canopies

抄録

It is important in river environment and hydraulic engineering to reveal the hydrodynamic properties in vegetated open-channel flows, in which velocity profiles are largely changed in the vertical and spanwise directions. In particular, vegetated canopies generate coherent turbulent motions (such as sweeps and ejections) which promote erosions and depositions of sediment on beds.Therefore, it is needed to investigate these turbulence mechanism and coherent vortices in order to maintain the vegetations in actual rivers. In this study, we conducted turbulence measurements by using PIV technique, and revealed the turbulence structure in open-channel flows with vegetated canopies.
