The effect of temperature on the settling velocities of an estuary mud

The report describes an extension of the studies discussed in a previous report "A detailed study of the settling velocities of an estuary mud", Report No INT 78, September I97O.

Further detailed tests on a mud obtained from Avonmouth in the Severn Estuary were carried out in a bottom withdrawal tube 2 metres high to determine the effect of temperature on settling velocities.

After allowi.ng for changes in the viscosity of the suspension due to the variation in temperature, the settling velocities were found to vary little with temperature, with only a slight tendency towards greater flocculation and higher settling velocities at increasing temperatures.
