Sediment transport occurs in natural stream beds at least in part as bed load. These bed forms are typically classified as ripples or dunes depending on the bed morphology and flow conditions. Their equilibrium shapes are determined by the interaction between the flow, bed geometry and sediment transport field. The bed is then created by the flow and conversely, the flow is acted on by the bed form. Vertical sorting of sediment mixtures within dune structures was measured experimentally by conducting three types of experiments: running water experiments, still water experiments and air experiments. The results of these experiments show the vertical sorting process within the 2D dunes and the importance of the hydrodynamic force on the sorting process.
