ABSTRACT: In this paper, a two-dimensional transport model based on the semi-analytical solutions is presented for the analysis of pollutant migration beneath a landfill site. The transport region composes of heterogeneous porous media where the transport processes are affected by mass transfer between the flowing volume in macropores and the stagnant volume in micropores (capacitance concept). The contaminant source (e.g., a landfill site) is approximated using unsymmetrical finite Fourier series. The parametric study reveals the significant influences of the transverse transport properties on the contaminant longitudinal spreading and breakthrough curves, which cannot be produced by a one-dimensional model.
