Suspensions may be acceptably stable to sedimentation for two reasons. Either the bulk material has a yield stress high enough to hold the particles in suspension, or the material has a ''zero shear viscosity'' high enough that sedimentation occurs in an acceptably slow manner.

Clastic transport and fluid flow ... Thus knowledge of hydraulics, the science of fluid flow, is essential to sedimentation and stratigraphy. Fluids resist forces that tend to change their volume, but readily alter their shape in response to external forces. The ability of a fluid to entrain particles is dependent on: ... viscosity.

The former theory describes the viscosity as a function of shear rate, while the latter predicts the stress increase in a Couette device due to sedimentation. The connection between the two theories is made by identifying the aggregate parameters with the hard sphere parameters (size and volume fraction).
