Roughness of reverse flow over dunes and its application to the modelling of the Pitt River / by Y.L. Lau.: En13-5/86-109E-PDF

"Experiments using artificial dunes show that the friction factor is reduced when the steep face of the dune is on the upstream side, i.e., when the direction is reverse that of normal. Calculations using bed-form regime relationships show that this configuration of reverse flow over dune profiles could have existed in the Pitt River, causing the decrease in bed roughness which was found during the calibration runs"--Abstract.
