Includes bibliographical references. "In many rivers complete sectional mixing is not achieved for long distances from the initial release point of a pollutant. This is the case for the Athabasca River downstream of Ft. McMurray where the release of contaminants from the Tar Sands refinery operations. A two dimensional toxic chemical model is being developed at NWRI to examine the transport and fate of these contaminants. Because of the complex nature of the mixing processes, field tests are required to supply mixing data for the model for a wide range of flow conditions. In order to supplement the few tracer dye studies which have been performed, the mixing of natural water quality parameters at the confluence of the Athabasca and Clearwater Rivers has been used to simulate a steady-state tracer test. The diffusion and dispersion values obtained from this study are compared with earlier dye tracer studies as well as a similar natural water quality tributary mixing study performed 18 years earlier"--Abstract. gccst Rivers gccst Hydrology gccst Models Canada.
