Abstract: Simulated drifting snow patterns were examined for a single structure using fine sand and water in a hydraulic flume. Three models of the structure were constructed at different scales and the experimental data revealed that model scale had very little effect on the areal distribution patterns. Flow velocity also had very limited influence on the drift patterns, provided the channel velocity was greater than the threshold velocity of the sand particle. Lengthening the duration of the test runs made it easier to distinguish the patterns but did not change their shape. The above experinental data suggest that modeling under the concept of Reynolds number independence is satisfactory.
