The validity of Kynch theory to describe the sedimentation of clayey slurry is investigated, the theory is reviewed and the kinetics of the problem are considered. This allows the development of the permeability-versus-void-ratio relationship from the surface settlement versus time curve of a batch sedimentation test. Emprirical modifications to Kynch's theory are introduced to extend the theory to clayey slurry. The modifications do not alter the graphical nature of the approach. The study found that for clayey dispersion, the permeability-versus-void-ratio (or concentration relation) also depends on the initial condition to reflect the flocculating nature of the dispersion. Kynch's theory in its original form does not account for this dependence and thus needs to be modified. These and other study findings are discussed.
