Synopsis:

The course focuses on processes affecting the transport of water-dissolved chemicals in natural porous systems. In addition to reactive substances, conceptualization of basic transport processes is considered for non-reactive (conservative) substances. The emphasis is put on mathematical description of water movement and transport of solutes in soils including transformation processes (initial and boundary conditions, governing equations, analytical and numerical solution, parameterization of transport coefficients). Attention is also be paid to the concept of breakthrough curve, parameterization of sorption and degradation processes, description of chemical transport using a two-region/two-site model, existing databases of transport parameters of organic compounds, and different approaches used to assess mobility of organic compounds in the vadose zone.
