Description :
The AA. report the wind tunnel results of systematic tests of the flux profiles of different sized sands at different free-stream wind velocities. The results reveal that within the 60-cm near-surface layer, the decay of blown sand flux with height can be expressed by an exponential function. The AA. define the physical significance of the parameters in flux profiles and their relationship to grain size and wind velocity. They also discuss the average saltation height of blown sand and the influencing factors.
