Abstract
Characteristics of open channel flow with suspended sediments were theoretically investigated introducing a theory based on the Monin-Obukhov length. First, a velocity distribution equation based on the theory showed a good agreement with the measured velocity distribution. Second, the hydraulic resistance and the distribution of suspended sediment concentration observed in experiments were explained theoretically. Third, a transport rate formula for suspended sediments, in which classical equations were included as a particular case, was obtained; and this formula, in cooperation with a reference concentration derived in the present study, showed agreement with experimental results. Finally, the critical condition for deposition of suspended particles and the collapse of turbulence were derived and verified by experiments.
