Objective(s): The primary objective of this project is to develop improved understanding of the fluxes of water and energy in northern regions, and to develop improved computer models of these processes. This work is an important contribution to the Canadian GEWEX program, which is aimed at developing an improved understanding of both the atmospheric and land surface water budgets of the Mackenzie Basin, and the Canadian Foundation for Climate and Atmospheric Sciences to consider methods to improve the prediction of climate change. This study will provide improved techniques for predicting a wide range of environmental impacts in northern areas, including potential climate change impacts, and implications to northern oil and gas interests (PERD). In detail this work will include studies of the rates and processes controlling: accumulation of snow, snow melt, water flux through snow, exchange of water between snowcover, active layer and permafrost; movement of solutes and nutrients through the snowcover and to the stream channel; the effect of snow/soil temperature regime and vegetation types on runoff processes; evaporation processes; and development of physically-based, predictive models of snowmelt runoff.
