pastas.recharge.FlexModel.get_root_zone_balance

static FlexModel.get_root_zone_balance(pe, ep, srmax=250.0, lp=0.25, ks=100.0, gamma=4.0, dt=1.0)

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.

Return type

Tuple[ArrayLike, ArrayLike, ArrayLike, ArrayLike, ArrayLike]
