Abstract


Experiments in flumes (i.e., Kemp and Simons, 1982, 1983, and Klopman, 1994) have shown that the mean current profile for following waves is more uniformly distributed than the corresponding current-only case, whereas the case of an opposing current leads to a more straight profile. This paper is concerned with proving that inclusion of the so-called Craik-Leibovich (CL) vortex force in the mean-current equation gives, at least for a part, an explanation of this phenomenon.

Keywords
