Abstract
The influence of revetment on wind current at closed shallow water regions was examined by water tank experiment using PIV. The wind current changes its direction in the region close the revetment and becomes the countercurrent near the bottom of the water tank. Velocity and velocity fluctuation of countercurrent are large at the revetment side. They are smaller at the offing side. They vary with angle of the revetment. The revetment with gentler angle realizes higher velocity and fluctuation at offing side. These results suggest sediments on the bed near gentle slope are easily transported in closed shallow water regions.
