摘要：

The wave-current friction coefficients and the phase lead of the bottom shear stress over the free-stream oscillatory velocity for rough, smooth and transitional smooth-to-rough turbulent flow are presented. The analogy between wave boundary layer flow and planetary boundary layer flow is utilized by using similarity theory. The turbulent current is described by using a simple eddy viscosity representation. An approximation for the friction coefficients by disregarding the phase is also presented. Comparisons are made with experiments for rough and smooth turbulent flow. © 1990.
