A Transport Rate Formula for Mixed-Size Sands
Experiments were conducted on the transport of mixed grain size sands due to nonlinear waves, over both rippled and flat beds. The sand mixture was composed of a fine sand with median diameter of 0.2 mm and a coarse sand with median diameter of 0.87 mm. Conditions for the initiation of sheet flow were investigated and transport rates were measured. It was found that the transport rate of fine sand is significantly reduced by the existence of the coarse sand, whereas the coarse sand behaved almost as if there were no other sand present. A transport rate formula for mixed sands was presented and verified by using the measured data.
