Abstract

In this paper,the mechanisms which dissipate the enregy of waves propagating on a current are considered. It is shown that the surface slope of an actual uniform current plays an important part for the variation of wave height attenuation rates with the intensity of the current. The surface slope enhances the attenuation of waves propagating on an opposing current and weakens it for a following current. It is also shown that,as the wave attenuation rate increases in stronger opposing currents,it affects the change in height of waves on a gradually varying opposing current to such an extent that we can not ignore the effect.
