Abstract
Elastic and yield phenomena of cohesive sediments are usefully studied with pulse shearometry and an applied stress rheometer combined with vane geometry. These sediments are elastico-viscous materials at volumetric concentrations ϕ equal to or greater than the critical concentrations ϕ SF at which a space-filling network exists in the sediment. Vane geometry provides reliable estimates of yield stress (Γ y ) in fresh, undisturbed sediment. Γ y and shear rigidity modulus G are strongly dependent on ϕ.
