Living Snow Fence Case Study: Mountain Lake, MN
	Introduction   Snowfall   Wind Direction   Fetch Distance   Snow Water Equiv.   Snow Transport   Porosity Attack Angle   Setback   Conclusions   References The attack angle of the prevailing winter wind striking the road is used to determine the fence's setback. The most important consideration for attack angle is the predominant direction of snow transport, or the prevailing direction of the greatest amount of snow transport. In this case, the wind direction should be taken as 320°. With a East-West highway, the attack angle of the wind striking the road is 60°.         Wind Variables Prevailing winter wind direction (Oct.-Mar) 320° Prevailing winter wind direction of snow transport 320° Wind direction used as attack angle 320°       close this window
