The selected approach has the following characteristics: ♦ the model is spatially distributed in order to represent the heterogeneity of the medium ♦ the model is strongly coupled in order to apprehend the physical complexity of flow systems We use for this purpose a strongly integrated model, governed by a single generic equation (PDE) based on generalized Darcy law, to describe different flow ‘regimes’ co-existing in the same domain, while conse...
