Results from settling experiments in an annular flume using kaolinite clay in distilled water are presented. Identical experiments carried out at different temperatures show that as temperature decreases, a larger proportion of the material initially suspended will settle out. The overall settling velocity is also higher at lower temperatures, in direct contrast to published results from settling tube experiments. A possible cause for this temperature effect is given.
