Fluid-sediment interactions and dynamic shear stress in fine sediment suspensions
Abstract
The effects of flocculation on the rheology of fine sediment suspensions are inverstigated. It was found that the dynamic shear stress increases with the increasing sediment concentration and increases logarithmically by increasing the salinity of the suspension. The salinity dependence of the dynamic shear stress was correlated with changes in floc-size. These results reflect the dominant influence of fluid-sediment interactions on the flocculation behavior of the suspension. An analytic model predicting shear stress as a function of electrokinetic properties of the fine sediment suspension is developed.
