Description :
This paper presents a conceptual model of wind erosion by saltating grains in which the erosion rate is determined by the strength of the surface and the energy delivered to the surface by the saltating grains. Methods are presented for the measurement of both distributions and consequent loss of material from the bed. It is concluded that saltating sand grains can rupture weak crusts under even moderate wind conditions, and that the rate of erosion will depend on the shape of the distribution tails.
