Compétition entre transport et rétention de matière en milieu poreux

Abstract : Many break-through curves, especially with passive tracers in unsaturated porous media, show power-law decrease. Such a behaviour is not compatible with Fick's and Fourier's laws. Nevertheless, it fits a wide class of partial differential equations involving time-non-local mappings. Moreover, that equations are the macroscopic limit of many small-scale models. The result was proved, on the basis of a probabilistic method, in the case where all parameters are constant: it is illustrated numerically by simulations in more general situations
