Wind Protection
To Shelter Livestock

Shelter Dimensions
Both the semicircle and the wedge (90-degree V-shape) provide wind protection with minimum snow in the shelter zone, as long as shelter width (across the wind) is no greater than 15 times the shelter height. In the diagram, dimension D should be 15 H or less, to divert drifting around the protection zone. From wind speed measurements, we found the zone with at least 60 percent wind reduction extended about 5 times the height downwind from the ends of the shelter. The width of the zone is about 85 percent of the shelter width. Figuring that each animal (or animal unit) needs about 50 square feet of the shelter zone, we've plotted the number of animals protected by shelters of various heights, when width D is 15 times height. The numbers are the same for either V-shaped or semicircular shelters.
