Pollutant Transport Through Barriers

by R. Kerry Rowe, Univ of Western Ontario, London, Ont, Canada,



Document Type: Proceeding Paper

Part of: Geotechnical Practice for Waste Disposal '87

Abstract:

Methods of predicting contaminant transport through saturated and unsaturated clayey barriers are reviewed. Particular consideration is given to the relative importance of advection and dispersion as transport mechanisms, the soil properties controlling transport, transport through saturated and unsaturated soils, contaminant transport through barriers and into adjacent aquifers, and finally, to methods of obtaining solutions to the transport equations. Based on this review, a number of specific observations and recommendations are made.
