Wind Tunnel Study

The transports rates on a sandy bed that grain sizes were bi-modally distributed were experimented in a wind tunnel. The results showed that the transport rate followed a power law and the power was 2.5, and that the threshold shear velocities were the same or somewhat larger than those of the large diameter sand in the mixture.
