Abstract
Results from the analysis of high-speed video recordings of sediment particle motion in the near wall region of a turbulent open channel flow are presented. Analysis of the video images provided information about characteristics of both, the process of particle entrainment into suspension and the process of particle saltation. Depending mainly on their size, sediment particles were observed to respond differently to the turbulence in the near bed region of the flow. While small particles tend to be entrained into suspension by ejection events related to turbulent bursting, larger particles tend not to respond to such events. Those particles were observed to move mostly in the saltation mode, which appears to be controlled mainly by the process of particle collision with the bed.
