   :staticmethod:


   
   Method to compute the water balance of the root zone reservoir.

   :param pe: Effective precipitation flux in mm/d.
   :type pe: array_like
   :param ep: Potential evaporation flux in mm/d.
   :type ep: array_like
   :param srmax: Maximum storage capacity of the root zone.
   :type srmax: float, optional
   :param lp: Parameter determining when actual evaporation equals potential.
   :type lp: float, optional
   :param ks: Saturated hydraulic conductivity in mm/d.
   :type ks: float, optional
   :param gamma: Parameter determining the nonlinearity of outflow / recharge.
   :type gamma: float, optional
   :param dt: time step for the calculation of the recharge. Only dt=1 is possible now.
   :type dt: float, optional

   :returns: * **sr** (*array_like*) -- Storage in the root zone reservoir.
             * **r** (*array_like*) -- Recharge flux in mm/d
             * **ea** (*array_like*) -- Evaporation flux in mm/d. Consists of transpiration and soil evaporation.
               Does not include interception evaporation.
             * **q** (*array_like*) -- surface runoff flux in mm/d.
             * **pe** (*array_like*) -- Incoming infiltration flux in mm/d.
