Vertical sorting within dune structure
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. Five different sediment mixtures with known initial gradations were used. The median grain diameters for the five sediment mixtures were between 0.35 mm and 0.86 mm, the geometric standard deviations of the same sediment mixtures were between 2.30 and 2.9. In the running water experiments, each experiment was continued until the dunes were fully developed down the flume. Then each dune was sampled ...
