Includes bibliographical references. "Experiments on the erosion characteristics of contaminated bed sediments from Hamilton Harbour were conducted in an annular flume. Sediments were obtained from the Kenilworth boatslip which receives coal pile runoff. Values of the critical shear stress for bed erosion were obtained for nine different runs. It was discovered that the presence of biofilm had very significant impacts on the erosion resistance of the bed as well as on the behaviour of the sediment flocs brought into suspension. Without any change in hydraulic conditions, sediments eroded from the bed were observed to settle out almost completely. Size distributions for the sediment flocs were obtained and discussed based on a conceptual model of floc recycling"--Abstract.
