Numerical and experimental simulation of pollutants migration in porous media
Abstract Quantitative prediction of pollutant migration is now of great interest in the field of waste management and storage. Numerical modelling of contaminant transport through porous media is an efficient tool to make this prediction possible. Site selection and design of protective liners for landfills and storage facilities are largely related to the behaviour of contaminants in such structures. This behaviour may be well defined by numerical simulations. This paper proposes a two-dimensional finite element model for pollutant migration. The implementation of the advection-dispersion equation in the numerical model and validation tests by comparison with analytical and semi-analytical solutions are presented. Experimental laboratory tests on cadmium and chloride migration through liner samples are also discussed and compared with the results from the numerical model.
