内容記述 | Vegetation in a river has a similar effect as permeable super dikes. Such an effect can be substituted by a group of cylindrical roughness. In this study, 3-dimensional flow structures and bed evolution were measured in a curved open channel with cylindrical roughness located along the outer bank. A series of cylinder decreased the scour at the outer bank. Especially submerged cylindrical roughness can reduce the bed evolution much more. Flow structures over the submerged cylindrical roughness have 3-dimensional characteristics. The lateral momentum transport due to the secondary flow was modeled from an examination of the experimental data. The mean flow distributions and bed evolution in curved channels with cylindrical roughness are well predicted by using the present 2-D numerical model. | |||||
