Résumé :
|
A finite layer technique for modelling contaminant transport from a landfill for relatively complex conditions is presented. The theory allows consideration of multiple units such a secondary leachate collection systems, hydraulic control layers or aquifers which can be used to remove contaminant from below the landfill. The theory allows consideration of time varying properties of the system. It also allows consideration of complex source concentration histories with time including the increase in concentration with time, constant source concentration for a period of time and decrease in concentration as mass is removed from the system. The application of the technique is illustrated with an example.
