Abstract: A knowledge about the effect of suspended material on the structure of the flow is of importance. The longitudinal mean velocity profiles are described reasonably well by Coles’law by using the wake-strength parameter, Π, being always larger than the ones used in clear-water flow. The profiles of the longitudinal component of the turbulence intensity, u′ 2) /u*, seem to be slightly enhanced by the presence of suspended sediment particles, while the ones of the vertical component, v′ 2) /u*, are clearly suppressed.
