Dewatering and the hydraulic properties of soft, sulfidic, coastal clay soils

White, Ian; Smiles, David; Santomartino, D; van Oploo, P; MacDonald, Bennett; Waite, T


Dewatering and consolidation of saturated swelling soils are governed by pressure-dependent soil hydraulic properties. Existing measurement techniques are difficult and slow. We illustrate a simple, rapid desorption technique, developed for industrial slurries, to measure hydraulic properties of a gel-like sulfidic, estuarine soil (∼70% water content). Measured hydraulic conductivities, K(ψ), were very small, ∼10-10 m/s, giving a representative capillary fringe thickness of ∼7 m and...[Show more]
