【 摘 要 】
Full scale laboratory flows producing vigorous bed load transport are conducted at varying periods but constant maximum velocities. The time-varying sediment transport in the first half cycle is measured using video imaging of dyed natural sand. The acceleration of the fluid (proportional to the frequency of the oscillation in these experiments) is found to significantly affect the velocity of the sediment response (bedload transport), and the phase and the absolute magnitude of fluid velocity associated with the initiation of sediment motion.
