Abstract
This talk will focus on recent trends in the timing and variability of observed river discharge in northern Canada. From a database of over 60 rivers from the Reference Hydrometric Basin Network (RHBN), the Mann-Kendall test is applied to assess trends on the annual and seasonal scales using 5-day (pentad) discharge for the latter half of the century onward. The study first focuses on changes in the timing of the spring snowmelt pulse and its spatial variation. Trends in the temporal variability of discharge are then discussed using moving averages of the annual and seasonal scale standard deviations in river discharge. Observed changes are placed in context of the different phases of large-scale teleconnections such as the PDO, ENSO and AO.
