Abstract: Experiments on sediment transport by two-dimensional uniform currents were carried out using wave-flow-sediment flume. It is found that the vertical distribution of suspended sediment concentration (SSC) agrees well with Rouse's equation, and the vertical sediment mixing coefficient is proportion to the vertical fluid mixing coefficient, and may be described by a para-bola. The maximum of vertical sediment mixing coefficient is related to hydrodynamics and SSC.

Key words: vertical sediment mixing coefficient, 2D uniform, vertical distribution of SSC, vertical sediment mixing coefficient, 2D uniform
