What physical situation arises when either a single grain or an array of sediment particles is released in a fluid of contrasted density? This question is sedimentologically interesting for at least two reasons. It relates to the ability of the wind, rivers, tidal currents and turbidity currents to transport sediment in turbulent suspension, and to the attitudes assumed by particles on deposition. Some valuable insights will come from the following experiments.
