The hydrologic roles of snow avalanches in high-mountain environments are rarely addressed by the research community. Yet, as a component within the snow and ice subsystem of the hydrologic cascade, avalanches can provide a significant source of accumulation for glaciers; alter the nature and timing of seasonal snowmelt; disturb the winter runoff regime through damming of rivers and displacement of lake water; and increase the incidence of other mass movement processes by their disruption of slope sediments. The purpose of this paper is to review the current state of knowledge with respect to these roles, particularly as they affect downstream hydrologic processes.
