Rheological boundaries of mud: Where are the limits?

  • Richard W. Faas


“Mud” includes a rheological criterion that implies it exhibits a particular consistency state, the lower boundary of which can be specified through the use of the Atterberg plastic limit, but the upper boundary remains undefined. A relationship between the water content of a hindered settling suspension when its structure changes from fluid-supported to body-supported and its Atterberg liquid limit appears capable of predicting the physical conditions at the moment when the suspension acquires a rheological character sufficient to define the upper surface of mud. This relationship appears consistent and predictable within various marine and estuarine environments.
