Abstract: This study used analysis of baseflow rates, deconvolved from readily available streamflow data, as a slow-process signal for examination of climate change issues in Canada. The work presented makes extensive use of Environment Canada's National Water Data Archive (EC, 2001) as well as the Automated Baseflow Separation utility ABSCAN (Parker, 2006). Results are compared and contrasted with an equivalent analysis using streamflow as the trend detection variable (Burn and Hag Elnur, 2002). The regional patterns of significant change were similar for baseflow and streamflow, but a greater percentage of significant trends were detected for baseflow, particularly for relatively short records. Analysis of changes in baseflow appears to be a useful means of detecting influence of climate change on regional hydrology.
