Abstract:

The objective of this investigation was to simulate conditions of drifting snow previously observed in the field in a laboratory hydraulic flume using a sand-water analog. Prototype conditions and model results were evaluated to define modeling parameters that would allow quantitative correlation between actual drift conditions and the model. Although exact similitude is not feasible, this modeling approach has proven useful in studies of snow conditions which defy theoretical prediction and would be very time consuming or impossible to evaluate in the field. Parameters examined in the model include prototype dimensions, flow velocity, geometric scale effects, structural porosity, and time.
