§ Temperature

2 Drainage layers and Leachate Collection Systems

Geosynthetic drainage layers
Long term performance of leachate collection systems
How to use (and NOT use) geotextiles in LCS systems

3 Geosynthetic Clay liners (GCLs)

Factors affecting long-term performance
Effect of method of GCL manufacture
Hydration and Hydraulic conductivity of GCLs
o Effect of stress
o Cation exchange
o Compatibility – hydraulic conductivity
o Internal erosion
Overlaps
Diffusion through GCLs (aqueous)
Gas migration through GCLs

4 HDPE Geomembranes (GMBs)

Material characteristics
Processes affecting short-term performance- leakage
Long-term performance
o Factors affecting long term performance
o Conventional immersion tests – MSW [OIT]
o Effect of GMB thickness [OIT]
o Service life for GMB in MSW
o Service life of secondary GMB in MSW
o Effect of temperature history on SL for MSW
Diffusion through GMBs

5 Composite liners performance and issues

Diffusion through composite liners
Protection of composite liners
High stresses – heap leach pads
GM wrinkling/waves
Temperature effects on CCLs and GCLs in composite liners (shrinkage and desiccation)
Leakage through composite liners
Effect of composite liner behaviour on GM service life

6 Contaminant transport predictions/modelling

7 Equivalency of GCLs and CCLs
