Event Title

Impact of landuse activities on fine sediment-associated contaminants: Quesnel River Catchment, BC.

Description

A clear association between fine sediments and the transport of contaminants within river systems has been documented for many river systems. Through remote sampling of tributaries to the Quesnel River with predominant land use associations, contaminant concentration signatures will be derived. Of interest is the spatial and temporal variation between sample sites representing different land uses, and in particular if each land use activity has a distinct contaminant signature. High energy events such as storms or spring flood water levels should provide the greatest yield of fine sediment and thus the greatest concentration of contaminants into the system. Using GIS presented land use areas within the Quesnel River watershed, the aggregate influence of fine sedimentassociated contaminant inputs at Quesnel can be extrapolated. Through a greater understanding of land use influence on contaminant concentration variability within this system, estimations will be made involving similar unstudied river systems.
