• Wet sieving | Article about wet sieving by The Free Dictionary

    Whilst the most accurate method of determining the settling velocity characteristics of soil is to use the bottom withdrawal tube methodology of Lovell and Rose (1988) in this paper the characteristics were determined by wet sieving to give a size distribution for Scone and Gunnedah which was then converted into settling velocity using the equation of Cheng (1997)
