"Sources of contaminants in the Great Lakes include sediment laden waters from harbours and rivers. The dispersion and settling of the contaminants in the lakes is linked to the depositional and erosional characteristics of the sediment under the influence of wave action. Fine-grained sediment and water from Port Stanley harbour on Lake Erie were exposed to waves in a laboratory flume. Depositional characteristics of the sediment were studied as a function of bottom stress and time (and hence bacterial activity). The flocculation of the sediment was studied by measuring the in situ size distribution of the sediment using a particle sizing instrument that operated on the principle of laser diffraction. Both smaller shear and increased elapsed time result in production of larger flocs and more rapid deposition. Implications for transport are discussed"--Abstract.
