Abstract

In studies of the erosion, transport, and deposition of dense near bottom suspensions of fine- grained cohesive sediment, it is often useful to ascertain the particular form of rheological behavior which may be exhibited by the suspension as it responds to the stresses imposed upon it by its environment. These forms of behavior may be time-dependent or independent, Newtonian or non- Newtonian and may show some or all forms of rheological behavior during an analysis, depending upon Environmental condition. For a treatment of suspension rheology, see VAN WAZER et al., (1963) and VAN OLPHEN, (1977). The purpose of this note is to describe in some detail an instrument which has been used to make observations of these phenomena, to discuss its usefulness for laboratory and field analyses, and to suggest that it be considered an important tool for understanding and predicting the dynamic behavior of such material.
