Abstract

This paper concerns the interaction of waves and currents, and in particular the effect of the time-averaged vorticity distribution associated with a sheared current. Laboratory data describing both the "initial interaction" of waves and currents, and the "equilibrium" conditions arising within an established wave-current combination are presented. These results are compared to both the existing irrotational solutions and a multi-layered numerical model capable of describing an arbitrary current profile. The interaction of regular waves and sheared currents is shown to be in good agreement with this latter solution. However, a similar description of random waves on sheared currents is limited by the wave-induced changes in both the mean current profile and the associated turbulent structure.
