Geosynthetic clay liners (GCLs) play a major role in optimising the hydraulic performance of today’s barrier systems. Numerous researches have been carried out to evaluate and enhance hydraulic...

Nine issues of importance to the use of geomembranes (GMs) and geosynthetic clay liners (GCLs) as part of composite liners in geoenvironmental applications are examined. These issues include the effect of: GCL-leachate compatibility on hydraulic conductivity; freeze-thaw on GCL performance; internal erosion on GCL hydraulic conductivity; temperature on advection and diffusion as well as desicca...

in this research, hydraulic and sorption behavior of geosynthetic clay liners (gcls) withordinary and modified clay exposed to crude oil were studied. both modified and ordinary bentonites wereinvestigated to evaluate crude oil adsorption efficiency on the liners. because soil permeability exposed tocrude oil is a major parameter in measuring the contaminants migration in soils, the permeabilit...

Abstract Geosynthetic clay liners are widely used as hydraulic barrier due to their low conductivity but bentonite in the loses its effectiveness significant thermal fluxes by both diurnal and seasonal heating cooling cycles. Modified sodium carboxy methyl cellulose-based (HYPER clay) has shown better performance situations. A possible reason for this improved of HYPER based geosynthetic liner ...
