|
* \brief A water infiltration problem with a low-permeability lens
|
|
* embedded into a high-permeability domain.
|
|
*
|
|
* The domain is rectangular. The left and right boundaries are
|
|
* free-flow boundaries with fixed water pressure which corresponds to
|
|
* a fixed saturation of \f$S_w = 0\f$ in the Richards model, the
|
|
* bottom boundary is closed. The top boundary is also closed except
|
|
* for an infiltration section, where water is infiltrating into an
|
|
* initially unsaturated porous medium. This problem is very similar
|
|
* the \c LensProblem, with the main difference being that the domain
|
|
* is initally fully saturated by gas instead of water and water
|
|
* instead of a \c DNAPL infiltrates from the top.
