static pastas.recharge.FlexModel.get_root_zone_balance(pe: pastas.typing.ArrayLike, ep: pastas.typing.ArrayLike, srmax: float = 250.0, lp: float = 0.25, ks: float = 100.0, gamma: float = 4.0, dt: float = 1.0) → tuple[pastas.typing.ArrayLike, pastas.typing.ArrayLike, pastas.typing.ArrayLike, pastas.typing.ArrayLike, pastas.typing.ArrayLike]#

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

Parameters:

  • pe (array_like) – Effective precipitation flux in mm/d.

  • ep (array_like) – Potential evaporation flux in mm/d.

  • srmax (float, optional) – Maximum storage capacity of the root zone.

  • lp (float, optional) – Parameter determining when actual evaporation equals potential.

  • ks (float, optional) – Saturated hydraulic conductivity in mm/d.

  • gamma (float, optional) – Parameter determining the nonlinearity of outflow / recharge.

  • dt (float, optional) – time step for the calculation of the recharge. Only dt=1 is possible now.

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.
