Abstract

The automatically recording settling tube at the University of Southern California was calibrated using small groups of glass beads. The settling times were adjusted too a specific gravity of 2.65 and the calibration extrapolated for different temperatures. The calibration does not compensate for interaction among settling grains, but this factor may significantly influence the deposition of aqueous sands. The range of calibration and laboratory error for the settling tube is small compared to the textural variation of natural sands.
