Moreover, hindered settling starts to influence the settling behaviour of sediment particles at volumetric concentrations of merely a few per cent. For example, the particle settling velocity in flows that carry 5% silt is re-duced by at least 22%. These observations suggest that hindered settling greatly WebbAbstract. The settling of relatively concentrated suspensions of fine particles can be analyzed theoretically by analogy to a fluid moving up through a static bed of packed particles. Using this analogy an equation was developed describing the hindered settling phenomena in terms of a relation between two dimensionless groups-the Froude group ... metamorphosis essay topics
