Measurement of Settling Velocity of Fine Sediment Using a Recirculated Settling Column

Claus Johansen, Torben Larsen

Abstract


The paper describes a new experimental method for the measurement of the settling velocity of fine sediments. The method includes determination of the influence of turbulence and concentration. The paper also illustrates the method by giving results of the settling velocity of kaolinite for varying turbulence, concentration and salinity
