pastas.recharge.FlexModel.get_interception_balance

static FlexModel.get_interception_balance(pr, ep, simax=2.0, dt=1.0)

Method to compute the water balance of the interception reservoir.

Parameters

• pr (array_like) – NumPy Array with rainfall in mm/day.

• ep (array_like) – NumPy Array with potential evaporation in mm/day.

• simax (float, optional) – storage capacity of the interception reservoir.

• dt (float) – time step used for computation. Only dt=1.0 is possible now.

Returns

• si (array_like) – Interception storage.

• ei (array_like) – Interception evaporation.

• pi (array_like) – Incoming rainfall that is intercepted.

Return type

Tuple[ArrayLike]

Notes

The water balance for the snow storage reservoir is defined as follows:

\[\frac{dS_i}{dt} = P_r - E_i - P_e\]

where $S_i$ [L] is the interception storage, $P_r$ [L/T] is the incoming rainfall, $E_i$ [L/T] the interception evaporation, and $P_e$ [L/T] the overflow from the interception reservoir.
