Abstract
ABSTRACT The present study is devoted to the simulation of nonlinear sorbing plume transport in homogeneous and heterogeneous saturated porous media. This study was performed by means of Monte Carlo simulations. For each Monte Carlo simulation, two problems have to be resolved. For the flow problem, the mass conservation equation, coupled with Darcy's law, is solved on a regular grid by means of a finite volume method. For the transport problem, the advection—dispersion equation is solved by means of a particles method. This langrangian method is based on a discretization of concentration field with particles defined by a location and a weight. At each time step, the transport problem is then resolved by evaluating the new location and weight of particles.
