Hydrological processes across three large middle arctic watersheds, Boothia Peninsula, Nunavut

A hydrological processes study was undertaken across the Lord Lindsay River and major East and West Tributary watersheds (1485, 465 and 345 km 2, respectively) on the Boothia Peninsula, Nunavut. Two seasons of hydrometeorological conditions were monitored across the catchments in order to characterize the scaled hydrological response of this environment to snowmelt and rainfall events.; The catchments exhibited snowmelt dominated streamflow during the spring flood period followed by a progressively dominant soil water response. Snow and soil water survey results showed considerable variability both at a spatial and inter-annual scales, further emphasing the challenges of obtaining conservative and representative end member values for hydrograph separation.; Substantive suspended sediment transfer occurred only during the short-lived nival peak and the duration of the peak appears to be broadly scaled with intra-annual catchment snow water equivalence (SWE). Total annual suspended sediment load in this environment is ultimately a function of total discharge through SWE rather than a function of melt energy. (Abstract shortened by UMI.)...
