STUDIES OF SNOW MOVEMENT IN A WIND DUCT.

Abstract

Drifting snow in polar areas with permanent snowfields presents problems in logistics and maintenance. To better understand the physics and mechanics of snow movement, studies are being conducted at the U. S. Naval Civil Engineering Laboratory in a 23-1/2-foot-long wind duct at wind speeds from 5 to 20 mph with temperatures from -35 to +20F. At these speeds, movement of in-place snow on the floor of the tunnel depends on the amount of snow added to the airstream. The amount of in-place snow moved is dependent on wind velocity, air temperature, exposure to solar radiation, and the physical properties of snow. Wind-duct tests using snow should be continued to determine the effect of prolonged wind, solar radiation, snow temperature, and varied surface patterns on drifting. (Author)
