Migrating Sedimentary Waves in a Large Test Channel
The importance of sedimentary waves that develop on the beds of alluvial streams has been recognized for many years. The roughly triangular features, known as ripples or dunes, that occur under tranquil flow, impart a large friction factor to the flow (Einstein and Barbarossa, 1952). They affect the transport rates of bed material by the contribution of their downstream migration to the bed load and by suspension enhancement by the additional turbulence that they induce (Willis, et al., 1972).
