Research Abstract |
Three-dimensional wave ripples were examined through laboratory experiments using two-directional oscillatory bed, which was newly developed in this study. The experiments showed that ripple formation processes and their formative conditions under steady two-dimensional oscillatory flow and those under unsteady one-dimensional oscillatory flow.
