内容記述 | Vegetation in a river may affect the 3-D flow structures and can control the local scour and accumulation in curved open channels. In this study, three-dimensional mean flow structures were measured in a curved open channel with various vegetation arrangements. Furthermore, experiments were conducted in a movable bed and the effects of vegetation on the local scour were examined. The secondary flow is generated only in the region outside the vegetation zones and the lateral scale of the vortex structures in bends are reduced. The main flow indicates complicated behaviors affected by the strong lateral shear, centrifugal force and momentum transport by the secondary flow. In movable beds, the secondary flow develops fast and becomes about 1.5 times larger than that in fixed beds. The vegetation changes the bed configuration through the change of mean velocity field. | |||||
