Solute transport in heterogeneous soils

Abstract:

If applied to real field situations simulation models have to cope with the intrinsic heterogeneity of field soils and the variability of boundary conditions. Complex approaches often fail here because the spatial distribution of parameter functions can in general not be measured (or otherwise assessed) with sufficient accuracy. The boundary conditions are often partly unknown. By way of several case studies, I will illustrate typical sources of variability encountered in applications and present simplified approaches that were successful in modeling the fate of environmental chemicals in field soils at different scales.
