Includes bibliographical references. "Field measurements of suspended sediment transport carried out in the Athabasca River near Hinton, Alberta, Canada, are described. The objective of the measurements was to examine the influence of pulp mill effluent entering the river from a nearby pulp mill, on the suspended sediment. The results of the field measurement showed that the effluent had a significant impact on the transport of the sediment. Specifically, the effluent increased the deposition rates of the sediment and caused a substantial reduction of sediment concentration in reaches downstream of the effluent outfall. The reduction in sediment concentrations and the concomitant sediment load can only be attributed to the pulp mill effluent as there were no abrupt changes in the hydraulic characteristics of the river in the reach of interest. These observations were also confirmed by a laboratory experiment conducted in a newly built circular, rotating flume at the National Water Research Institute at Burlington, Ontario, Canada. The findings of this study have implications for modelling sediment transport in rivers receiving bleached pulp mill effluent"--Abstract.
