"Flocculation is a well-known phenomenon in marine science and sanitary engineering. Little, however, is known of the existence and nature of flocculated suspended sediment within the freshwater fluvial environment. We examined the suspended sediment characteristics of a Southern Ontario river in order to determine the nature of flocculated suspended sediment and the factors which may influence it. It was found that flocculated suspended sediment was the primary mode of fine-grained mineral sediment transport in the river. Flocs were composed of both organic and inorganic grains and interstitial voids. Bacterial content associated with suspended sediment, suspended solids concentration and particulate organic carbon are believed to be important controlling factors of flocculation. Flocculation is known to affect sediment deposition, and bacteria associated with flocs may play an important role in contaminant pathways"--Abstract.
