\f}
* is frequently used to
* approximate the water distribution above the groundwater level.
*
* In contrast to the full two-phase model, the Richards model assumes
* gas as the non-wetting fluid and that it exhibits a much lower
* viscosity than the (liquid) wetting phase. (For example at
* atmospheric pressure and at room temperature, the viscosity of air
* is only about \f$1\%\f$ of the viscosity of liquid water.) As a
* consequence, the \f$\frac{k_{r\alpha}}{\mu_\alpha}\f$ term
* typically is much larger for the gas phase than for the wetting
* phase. For this reason, the Richards model assumes that
* \f$\frac{k_{rn}}{\mu_n}\f$ is infinitly large. This implies that
* the pressure of the gas phase is equivalent to the static pressure
* distribution and that therefore, mass conservation only needs to be
* considered for the wetting phase.
*
* The model thus choses the absolute pressure of the wetting phase
* \f$p_w\f$ as its only primary variable. The wetting phase
* saturation is calculated using the inverse of the capillary
* pressure, i.e.
\f[
S_w = p_c^{-1}(p_n - p_w)
\f]
* holds, where \f$p_n\f$ is a given reference pressure. Nota bene,
* that the last step is assumes that the capillary
* pressure-saturation curve can be uniquely inverted, so it is not
* possible to set the capillary pressure to zero when using the
* Richards model!
