This technique is capable of acquiring simultaneous sand-mixing velocities at high accuracies based on two high-resolution/high-speed video cameras with optical filters. In this paper, a suspension process of sands over the Dunes via mixing process in separated vortices and turbulence disturbances is characterized in terms of turbulence statistics on the basis of the measurement results, and statistical properties of turbulence induced by the suspended sediments is identified.
