Abstract
The stable isotope composition of water and major ion concentrations were measured in a small catchment tributary to Manners Creek, situated in the zone of discontinuous permafrost near Fort Simpson, Northwest Territories. Hydrograph separation calculations based on delta-18-O and delta-2-H values of snow, active layer water, and streamflow reveal that snowmelt contributions were secondary to active layer storage contributions throughout the spring freshet period of 1990. At the time of peak spring runoff an estimated 40-50% of streamflow was contributed by snowmelt, while over the entire spring period only 25-30% of streamflow was contributed by snowmelt. Overland and pipe flow are shown to be important mechanisms of rapid snowmelt runoff from permafrost slopes.
