| Zusammenfassung |
The classical models developed for degradation and
transport of xenobiotics have been derived with the assumption of homogeneous environments. Unfortunately, deterministic
models function well in the laboratory under homogeneous conditions but such
homogeneous conditions often do not prevail in the field. A possible solution is the incorporation
of the statistical variation of soil parameters into deterministic process models. This demands
the development of stochastic models of spatial variability. To this end, spatial soil
parameter fields are conceived as the realisation of a random spatial process.
Extrapolation of local fine scale models to large
heterogeneous fields is achieved by coupling deterministic process models with random spatial
field models. |
