Influence of Various Types of Field Windbreaks on Reducing Wind Velocities and Depositing Snow
Abstract:Comparisons were made of wind velocities and snowdrift patterns on the windward and leeward sides of windbreaks and slat barriers of varying numbers of rows, designs., and densities. Density was determined by placing a dotted grid over a picture enlargement and then computing the space occupied. Windbreaks and barriers which were permeable in the lower half of the structure caused snowdrifts to form over a wider area than the less permeable ones. Such permeable structures also reduced most erosive wind velocities to a nonerosive rate. Between a series of windbreaks spaced 400 feet apart wind velocities and snowdrift deposits indicated the series had no cumulative effect on wind reduction. Proper tillage practices must still be used in conjunction with windbreaks or other structures to control wind erosion of fields.

More about this publication?
- The Journal of Forestry is the most widely circulated scholarly forestry journal in the world. In print since 1902, the Journal has received several national awards for excellence. The mission of the Journal of Forestry is to advance the profession of forestry by keeping forest management professionals informed about significant developments and ideas in the many facets of forestry: economics, education and communication, entomology and pathology, fire, forest ecology, geospatial technologies, history, international forestry, measurements, policy, recreation, silviculture, social sciences, soils and hydrology, urban and community forestry, utilization and engineering, and wildlife management. The Journal is published bimonthly: January, March, May, July, September, and November.
