[case] WettingPhaseVanGenuchten

van Genuchten model model: wetting phase

\[k{rel}= \sqrt{S_e} (1-(1-S_e^{1/m})^m)^2)\]

with

\[S_e=\frac{S-S_r}{S_{\mbox{max}}-S_r}\]

where

\begin{eqnarray*} &S_r& \mbox{ residual saturation,}\\ &S_{\mbox{max}}& \mbox{ maximum saturation,}\\ &m(<=1) & \mbox{ exponent.}\\ \end{eqnarray*}

Note:

\[m=1/(1-n)\]
