In this work, we consider the transport of a surfactant in variably saturated porous media. The water flow is modelled by the Richards equations and it is fully coupled with the transport equation for the surfactant. Three linearization techniques are discussed: the Newton method, the modified Picard, and the L-scheme. Based on these, monolithic and splitting schemes are proposed and their convergence is analyzed. The performance of these schemes is illustrated on five numerical examples. For…

A model for the transport of an external component in variably saturated porous media is studied by combining a backward Euler method with the linear Galerkin finite elements and the effects of dynamic capillarity on the transport equation are studied.
