TY - JOUR T1 - Wind velocity patterns as modified by plastic pipe windbarriers JF - Journal of Soil and Water Conservation SP - 551 LP - 556 VL - 54 IS - 3 AU - J. D. Bilbro AU - J. E. Stout Y1 - 1999/07/01 UR - http://www.jswconline.org/content/54/3/551.abstract N2 - Windbarriers can reduce the damaging effects of wind erosion. Therefore, to obtain information that would facilitate the design of more efficient windbarriers, wind velocity patterns produced by various combinations of plastic-pipe windbarriers were studied. A one-row windbarrier with 12.5% optical density was the least effective, reducing downwind velocities over a 30-m (99-ft) distance by an average of only 4.3%. The most efficient windbarrier was a one-row windbarrier with 75% optical density, which reduced velocities an average of 32.5% over the 30-m (99-ft) distance. Equations were derived that can be used in the design of more efficient windbarriers to control wind erosion. ER -
