ABSTRACT
ABSTRACT: Depth-averaged analysis of flow and sediment transport has become familiar and powerful means in river management. When it is applied to a stream with vegetation, form drag due to vegetation is taken into account, but the change of frictional resistance law is not properly treated. Though the flow with non-submerged vegetation, the velocity is constant except only the thin layer near the bed where the shear flow appears due to bed roughness to govern the frictional resistance law. In this paper, the bed roughness boundary layer is investigated for reasonable estimation of shear velocity and subsequently bed load transport process.
