Recharge to the groundwater calculated based on Peterson and Western [2014].
The water balance for the unsaturated zone reservoir is written as:
\[\frac{dS}{dt} = P_e - E_a - R\]where the fluxes $P_e$, $E_a$ and $R$ are calculated as:
\[P_e = P \left(1 - \frac{S}{\hat{S_{cap}}}\right)^\alpha\]\[E_a = E_p \left(\frac{S}{\hat{S_{cap}}}\right)^\gamma\]\[R = \hat{k_{sat}}\left(\frac{S}{\hat{S_{cap}}}\right)^{\hat{\beta}}\]with the parameters:
\[\hat{S_{cap}} = 10^{S_{cap}}; \hat{k_{sat}} = 10^{k_{sat}}; \hat{\beta} = 10^{\beta}\]Note that the method currently uses forward Euler method to solve the ODE so significant water balance errors can occur.
