Query: An efficient numerical scheme for fully coupled flow and reactive
  transport in variably saturated porous media including dynamic capillary
  effects   In this paper, we study a model for the transport of an external component,
e.g., a surfactant, in variably saturated porous media. We discretize the model
in time and space by combining a backward Euler method with the linear Galerkin
finite elements. The Newton method and the L-Scheme are employed for the
linearization and the performance of these schemes is studied numerically. A
special focus is set on the effects of dynamic capillarity on the transport
equation.
