Abstract: The wave friction factor ππ€ and the phase lead of the seabed shear stress over the free stream velocity π for rough turbulent flow are revisited by utilizing the similarity theory used by Myrhaug (1989). Results are obtained for ππ€ and π by determining the similarity coefficients using the Dixen et al. (2008) data for large bed roughness. Comparisons are made with other experimental data and wave friction factor formulae. As a result, an approximation for ππ€ by disregarding the phase π is recommended covering a wide range of amplitude-to-roughness ratios.
