This approach treats sand as a diffusing agent rather than as projectiles that are affected by the wind only on the horizontal direction. The observed horizontal sand fluxes are shown to be in agreement with empirical formulas that express total horizontal flux of sand as a function of wind and soil parameters. References Armbrust, D.
