Modeling applied to environmental geotechnics

Invited opening lecture ABSTRACT The paper deals with basic and advanced theories for modeling mechanical, hydraulic, chemical and electrical phenomena of growing practical interest involving mineral barriers, polluted subsoils and waste landfills. In particular, four related and very topical issues are focused on: (1) prediction of short and long term behavior of geosynthetic clay liners (GCLs) for pollutants control; (2) modeling of multiphase mass and energy flows for speeding up contaminant extraction by electrical potential and (3) high vacuum; and (4) assessment of mechanical behavior of lining systems on old landfill for allowing side and vertical extensions.
