Abstract: Abstract The underlying physical processes and their specific properties are discussed, yielding a model for the spread of hydrophobic contaminants, which allows for numerical simulation. In the case of convection dominance the contaminant transport is approximated by means of a Lagrange-Galerkin approach. A numerical scheme is presented for transport with equilibrium sorption. Nonlinear sorption isotherms are identified with soil column experiments. The efficiency of the identification algorithm is mainly determined by the choice of an appropiate initial value and the numerical scheme to compute the gradient.
