Objective(s): To determine the rates and processes controlling: (1) the accumulation of snow, snowmelt and water flux through snowcovers; (2) the exchange of water between snowcover, the active ground layer and permafrost; (3) the movement of solutes and nutrients through the snowcover and to the stream channel; and (4) the effect of snow/soil temperature regime and vegetation types on runoff processes; to develop physically based, predictive models of snowmelt runoff.

Project Description: As part of a long-term study, the researchers will look at the role of the snowcover in controlling both streamflow and the movement of solutes/nutrients/pollutants through both tundra and forested ecosystems. Work will consist of measuring amounts and distribution of snow, streamflow and release of solutes/nutrients/ pollutants in two river basins at the end of winter.
