sedimentation tube Apparatus designed to determine rapidly the grain-size distribution of sand-sized sediment. The sedimentation-tube method is based on the principle of Stoke's law that particles of different sizes, shapes, and densities will settle through a column of fluid at different settling velocities. Sediment is introduced into the top of the settling tube, and the time is recorded for the various sediment fractions to settle to the bottom of the tube.
