Abstract: Geosynthetic clay liners (GCLs) were exhumed from composite barriers, (i.e., geomembrane over GCL) in final covers at four sites after 4.7 to 6.7 years to evaluate the in-service condition. Monovalent bound cations were ...

Abstract: This paper addresses the problem of a rigid block above the foundation subjected to a horizontal ground motion. The objective of this work is to formulate criteria that separate the sticked and the slipped modes of the ...

Abstract: AbstractThe stability of filtered tailings stacks requires a dense particle structure to be created via compaction following placement or potentially from desiccation due to atmospheric drying and/or compression due to ...

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 ...

Abstract: The hydraulic performance of geosynthetic clay liners (GCLs) comprising anionic polymer–enhanced bentonites (EBs), or EB-GCLs, based on permeation with 500 mM NaCl and 167 mM CaCl2 at an average effective stress ...

Abstract: Experiments were conducted to evaluate cation exchange during hydration of geosynthetic clay liners (GCLs) used in composite hydraulic barriers and the effect on their hydraulic conductivity. GCLs arranged in a composite ...

Abstract: The objective of this study is to compare the hydrology of prescriptive and water balance cover designs for Larimer County Landfill in Colorado via hydrologic models parameterized from laboratory-measured testing of ...

Abstract: Geosynthetic clay liners (GCLs) are increasingly used in engineering and environmental applications that include nonstandard solution chemistry. Long-term exposure of geosynthetics to nonstandard solutions in containment ...
