Abstract

Data from wind tunnel tests show that the presence of roughness elements (gravels, spheres) on a dry, flat sand surface affects the erosional capacity of the wind. Their influence is twofold: they activate erosion when their density is small and they protect the ground when their number is large. When the cover density is small, or the wind is strong enough, the spheres move in a direction opposite to the wind, at the same time digging themselves in the sand. Small quantities of soil moisture have a great influence on the susceptibility of the sand to deflation.
