Abstract

Shear velocity ratios were derived for 6 neighbouring localities representing rangeland, abandoned farmland and a playa, in the semi-arid region of the Sonoran Desert. Near-surface and above-canopy wind speeds, mostly below saltation threshold, were used to evaluate the partitioning of shear velocities and shear stresses between the plant canopy and the surface. Results are discussed with the goal of assessing the protection provided by sparse vegetation against wind erosion
