The modelling of moisture movement in engineered soil covers for mine waste rock dumps Swanson, D. A.; Barbour, S. Lee; Wilson, G. Ward

Abstract

A two-phased cover instrumentation and modelling research program has been initiated at a waste rock dump site. The first phase of the research program involves field instrumentation and monitoring of the inplace cover. The second phase involves modelling infiltration and evaporation in the cover system using a soil/atmosphere flux model that has been developed at the University of Saskatchewan. The soil/atmosphere model used is a one dimensional, transient, finite element, water and heat transport model that uses a physically based method to predict the exchange of water between the atmosphere and a saturated or an unsaturated soil surface. This paper describes the application of the soil/atmosphere model in predicting the field responses of the in-place cover system at the waste rock dump site.
