Effects of Terrain on Excessive Travel Distance by Snow Avalanches

Abstract
This study was undertaken to determine the characteristics of snow avalanches most likely to travel excessive distances across low-angle runout zones and perhaps onto opposite slopes. "Excessive' travel attained by snow avalanches is related to low equivalent coefficients of friction and large snow volume. In this study, wet-snow avalanches traveling down deeply incised, "hockey-stick profile' avalanche paths exhibited excessive travel. The equivalent coefficients of friction calculated for these avalanches were similar to those determined for far-traveling avalanches elsewhere. Conditions in the runout zone also affect excess travel, because early successional vegetation is less likely to impede continued avalanche travel than a mature forest environment. Land-use planners can utilize these observations in identifying particularly hazardous sites.
