Workshop 3

Predictive modelling and upscaling of flow and reactive transport in heterogeneous aquifers

Objective: The workshop programme introduces the mathematical and physical basis of flow and reactive transport in porous media, and the numerical methods for predictive modelling. It discusses scale effects for approaches based on the advection-dispersion equation and upscaling methods to get alternative effective equations (i.e., CTRW or MRMT for non-Fickian transport). Special emphasis is laid on mixing and mixing-controlled reactions in heterogeneous media as well as on field methods for the identification and characterization of non-ideal behaviour. Hands on practices on simple problems will illustrate predictive modelling honouring extensive data sets and acknowledges uncertainty.
