  1. Introduction - concentration, fluxes, particles.
  2. Lagrangian method (LPT3D)
    • Lagrangian Particle Tracking with Random Walk : advection-diffusion of tracer
    • Heterogeneous velocity fields : macro-dispersion analysis
    • Pure diffusion processes in heterogeneous and fractured media(interpolation scheme)
    • Reactive couplings (LPT3D-Gillespie)
  3. Eulerian "Particle-in-Cell" method for reactive transport : theMarkov Automaton (SMART)
    • Principle of the Markov Automaton for advection-diffusion-reaction processes
    • Application of the Markov AUtomaton for pure diffusion in heterogeneous fractured media
