The modeling of water flow and solute transport in the vadose zone requires a profound knowledge of the governing physical processes across scales. In a first part different approaches and tools to characterize properties at various scales will be presented. The second part will focus on the implementation of structural properties in the modeling of physical processes.

In this course the effect of heterogeneous structures in natural soil on water flow and solute transport is considered. In practical exercises, the theoretical material is applied to realistic scenarios through numerical simulations.
