Abstract: Soil-bentonite (SB) cutoff walls are commonly employed to control groundwater flow and contaminant migration, and the hydraulic conductivity (k) of the SB backfill is a critical parameter in these applications. In this ...

Abstract: Chemico-osmotic efficiency coefficients, ω, are determined from measured differential pressures across specimens of a geosynthetic clay liner (GCL) containing granular bentonite in response to applied differences in potassium ...

Abstract: Measured solute flux breakthrough curves (FBCs) from column tests performed on a semipermeable clay membrane subjected to KCl solutions are compared with predicted FBCs using independently measured flow and transport ...

Abstract: The effect of zeolite amendment for enhanced sorption capacity on the consolidation behavior and hydraulic conductivity,

Abstract: The potential for enhanced containment of two metals, potassium (K) and zinc (Zn), by soil-bentonite (SB) vertical cutoff walls comprising zeolite-amended backfills was evaluated on the basis of numerical transport simulations ...

Abstract: Flexible-wall permeability tests and rigid-wall consolidation/permeability tests were performed to evaluate the hydraulic conductivity and compressibility of a model soil-bentonite (SB) backfill amended with granular ...

Abstract: The containment function of soil-bentonite (SB) cutoff walls can be enhanced when the adsorption capacity of the SB backfill for targeted contaminants is increased. In this regard, the potential use of three commercially ...

Abstract: The factors affecting the applicability of electrical conductivity (

Abstract: Significant research conducted over the last 20 years has shown that engineered clay barriers for chemical containment applications can behave as semipermeable membranes that restrict the migration of aqueous-phase ...
