Includes bibliographical references. "In this report, the sediment transport studies undertaken in the Fraser river system as part of the Fraser River Action Plan are described. The studies consisted of field surveys and laboratory investigations. In the field surveys, the in-situ size distributions of the suspended sediments of the Fraser and Thompson rivers were measured using a laser device and were compared with the size distribution of the dispersed primary particles. From such comparisons, the flocculation state-of the sediments assessed. The laboratory investigations involved measurement of deposition and erosion rates of the river sediment under controlled conditions in the rotating circular flume of the National Water Research Institute. In addition, the influence of the pulp mill effluent on the flocculation mechanism of the sediment was also investigated in the laboratory. Based on the results of these investigations, a new mathematical model of the fine sediment transport was formulated for the Fraser river system"--Abstract.
