Several faculty conduct research in the broad areas of hydrology, glaciology and snow science. Hydrologic research focuses on the flow of water through the landscape and on physical water quality (suspended sediment and water temperature). Process studies at the plot, hillslope and small catchment scales are complemented by statistical analyses of hydrologic variables at the large catchment and regional scales. Glaciological research focuses on snow processes, avalanche dynamics, and hazard assessment; snow accumulation, melt and runoff; and glacier mass balance. Much of the research examines the effects of land use, particularly forest harvesting, and of climatic variability and change. Current projects include studies of the hydrology and thermal regime of headwater streams and their responses to forest harvesting with different riparian management strategies; avalanche prediction for heli-skiing operations and highways maintenance; interactions between snow avalanches and forest practices; climate-glacier-streamflow relations in the Southern Coast Mountains; scaling runoff processes from plots to catchments; and regional studies of snowpack, streamflow and water temperature variations.
