| Abstract: | In this paper high speed camera is used to measure the sediment transport near the rough bed in open channel tlow. The variation of saltation heigh of the single particle on the rigid channel is obtained as the following: The random variable obeys Γ-distribution The random distribution function of the single step length of the particle is also obtained asΓ-distribution: |
