Abstract:
The prime objective of barrier systems in modern Municipal Solid Waste (MSW) landfills is to minimize the contamination of ground water and surface water. Although Geomebranes (GMs) represent the primary barrier to leachate flow, leakage through perforated wrinkles and other defects in the GMs can occur and for the composite action to be most effective, it is important that the Geosynthetic clay liner (GCL) below the GM be intact and not fractured for the contaminating lifespan of the landfill. This presentation develops guidance concerning the design of Double Composite Liner Systems (DCLSs) with minimum desiccation risk and hence helps to improve the long term performance of the liner systems.
