The transport of heterogeneous contaminants in the subsurface is a very complex process and is influenced by a variety of factors. One approach to model such complex processes, as e.g. the pollutant transport, is by using simplified equivalent models. Under an equivalent model, a model with a simplified approach is to be understood, which considers only the essential aspects of processes, describes them abstract and still delivers realistic results. With an abstract representation of the processes it should be allowed to accept boundary conditions that lead to a simple solution of the problem. As an outcome, the complex process can be described qualitatively and despite the simplified assumptions the results should deliver realistic values. A statement on the actual processes taking place cannot be made here, since these actions are described equivalently. Based on the underlying physical and chemical processes equivalent models are created for particular cases to describe the transport of pollutants in the subsoil.
