Abstract

The Flocculation of cohesive fine-grained sediment plays an important role in the geophysical process in estuarine and coastal zones through the complete processes of sediment transport, deposition, re-suspension and consolidation. There have been many experiments studying the temporal evolution of the median floc size during flocculation. One typical trend is that the median floc size increases rapidly when the flocculation starts, and then increases slowly with flocculation time until a steady state is approached after a long flocculation time. In this study, an empirical expression used for characterizing the temporal variation of the median floc size during the flocculation process is proposed, and comparison with those published experimental results shows its validity.
