Controlling Soil Erosion From Wind
Blowing soil can be an unpleasant nuisance, a serious safety hazard, or a costly disaster depending on one’s perspective and the intensity and duration of the windstorm. The public response to blowing soil has led to such legislation as the Colorado Dust Blowing Law and provisions of the 1985 Food Security Act. Blowing soil or soil erosion by wind is a complex process. It involves detachment, transport, sorting, abrasion, avalanching, and deposition of soil particles. Turbulent winds above a threshold velocity (13 miles per hour at one foot above the ground) blowing over erodible soils can cause erosion or blowing.
