Abstract
Squamish River basin in SW coastal British Columbia is an important catchment in which a series of scientific studies of fluvial geomorphology, sedimentology, and Quaternary science have been completed during the last several decades. Here we review a half-century record (1956-2005) of daily discharge of Squamish River (at Brackendale) to evaluate hydrologic trends. Although the mean discharge series is stationary, that for large floods (>1500m3s-1) is strongly upward trending over time. This trend to increased extreme flooding appears to be driven by intensifying fall/winter storms that have increased rainfall intensity and storm duration. There is no evidence to suggest that endogenous hydrologic shifts related to landuse change are a significant factor. Channel changes have been documented elsewhere for Squamish River for the period 1947-1984; it is expected that the pattern of channel change has intensified over the last two decades. Investigation of this expectation is the subject of ongoing research at Simon Fraser University.
