Abstract: A three-dimensional multi-pod windblown particle control device is used to control the deposition, accumulation and retention of windblown particles. The multi-pod device is formed by connecting beams to create legs which intersect one another at a crossing area. The ends of some of the legs contact the earth surface to support the device while the ends of the other legs extend in three dimensions to interact with the wind. The device may be formed by substantially identical X-shaped frame structures which intersect and connect with one another. The optimal spacing for using the devices in an array is within a range of approximately 0.5-1.5 of a transverse dimension across the surface area occupied by each particle control device.

Abstract: A windblown particle control device which, when attached to the surface of the earth assumes a generally tubular cross-sectional shape, stabilizes particle cover and controls deposition and retention of windblown particles. A sheet of netting material is curved in an arched configuration. Webs of the sheet are linked together to define apertures through the sheet. The apertures create aerodynamic effects in the wind which stabilize, deposit and retain the particles on the earth surface. A kit of components, which includes the netting sheet and a plurality of frame structures to support and maintain the netting sheet in the arched configuration may be employed to assemble the control device for use.

Abstract: Windblown particles are controlled by a porous tubular control device formed from a sheet of netting material having a plurality of interconnected webs which define a plurality of apertures. The sheet of netting material assumes a three-dimensional tubular configuration. The tubular configuration is oriented to confront the wind and cause the wind blown particles to flow through the apertures of two vertically oriented portions of the tubular netting sheet to create aerodynamic drag and turbulence altering effects which stabilize, deposit and retain the windblown particles. The control device is effective in preventing the wind erosion of snow, sand or dust over an area much greater than the area occupied by the device.
