The objective of the paper is to give an update in key topics related to performance issues of
barrier systems for landfills. The objective of using barrier systems is to minimize the impact …

Advection-dispersion equations with first-order decay reactions are widely used to describe
the fate and transport of reactive contaminants, contributing to effective site contamination …

Back diffusion of pollutants from low-permeability aquitards to adjacent high-permeability
aquifers is a key issue that hinders site remediation. Previous back diffusion studies have …

This study proposed a semi-analytical solution for 2D electro-osmotic consolidation of
double-layered soil. The method of Laplace transform is employed to derive the solution in …

A triple-layer composite liner consisting of a geomembrane liner (GMB), a geosynthetic clay
liner (GCL) and a compacted clay liner (CCL) is commonly used at the landfill bottom liner …

Cutoff walls are widely used as in-situ vertical barriers to control pollution plumes migration
in aquifer. A two-dimensional analytical model for the transport of organic contaminants …

Bentonite based geosynthetic clay liners (GCLs) are commonly used as chemical
containment barriers to minimize liquid flow and contaminant transport. The preference for …

Electro-osmotic consolidation can be used as a valid and innovative technique for ground
improvement. Considering the limitation of previous studies that layered soil heterogeneity …

Contaminant back diffusion from low-permeability aquitards can result in long-term plumes
in adjacent aquifer systems, severely impeding groundwater clean-up. Hydraulic fracturing …

Breakthrough time based design methods for determining the design thickness of landfill
composite liners are proposed. The composite liners consist of either 1) a geomembrane …
