摘要：

A new wind tunnel has been constructed to study the mass transport properties of wind-blown sand. This report on the first set of experiments in the new wind tunnel concerns the effect of slope on threshold friction speed. The results of this series of static threshold experiments (and one dynamic threshold experiment) for a range of particle diameters and bed slope angles show that, provided the effects of Reynolds number variation and interparticle cohesive force are accounted for, the static friction angle a is independent of slope and close in value to the measured static angle of response.
