AB - <p style="text-align: justify;">In order to model the dispersal of volcanic particles in the atmosphere
and their deposition on the ground, one has to simulate an advection-diffusion-sedimentation
process on a large spatial area. Here we compare a Lattice Boltzmann
and a Cellular Automata approach. Our results show that for high Peclet regimes, the
cellular automata model produce results that are as accurate as the lattice Boltzmann
model and is computationally more effective.</p>
