Contaminant Transport through GML/CCL Bottom Liner with Consideration of Consolidation Effects
This paper presents a numerical investigation of the effect of compacted clay liner (CCL) consolidation on contaminant transport through a composite bottom liner system consisting of a geomembrane (GML) overlying a CCL. Numerical simulations were conducted using the CST2 model, which accounts for one-dimensional coupled large strain consolidation and contaminant transport in saturated porous media. Simulation results indicate that CCL consolidation can have a significant effect on contaminant transport through a composite GML/CCL bottom liner system, not only during the course of consolidation but also after the consolidation process has finished. Analyses based on diffusive transport alone neglect consideration of transient advection and changes of CCL properties caused by consolidation and can result in significant errors.
