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

Project Description: The Researchers will study the role of the snowcover in controlling both streamflow and the movement of solutes/nutrients/pollutants through both tundra and forested ecosystems. Computer models will also be developed to predict the distribution and properties of snow, its melt and runoff during the spring period, and the release of solutes/nutrients/pollutants from the snow.
