| Abstract: | The coherent structure of the turbulence and the interaction of the sediment and the bed are now much studied all over the world. The researches on the interaction between the turbulent coherent structure of the unidirectional flow and the oscillatory flow and the sediment are reviewed in this paper, in which the emphasis is on the studies on the turbulence of the oscillatory flow on the bottom layer. The major issues that should be studied in the future are pointed out and discussed in detail. |

| Keywords: | oscillatory coherent structure sediment motion bed form |
