A lattice gas model for erosion and particles transport in a fluid

We consider a simple lattice gas model to simulate erosion, deposition and particle transport in a streaming fluid. In our approach, the fluid is desc ribed by a standard lattice Boltzmann model and the granular suspension by a multiparticle cellular automata. A good agreement is obtained between the predictions of the model and field measurements, as observed by analyzing the deposition patterns resulting from various snow and sand transport phen omena. In particular we study the case of ripples formation and simulate th e scour appearing around a submarine pipe. (C) 2000 Elsevier Science B.V. A ll rights reserved.
