recharge#

Module containing the classes for recharge models.

This module contains the different classes that can be used to simulate the effect of precipitation and evapotranspiration on groundwater levels. Depending on the mathematical formulation this effect may be interpreted as:

seepage to the groundwater
precipitation excess,
groundwater recharge.

For the implementation of each model we refer to the references listed in the documentation of each recharge model.

The classes defined here are designed to be used in conjunction with the stressmodel “RechargeModel”, which requires an instance of one of the classes defined here.

Examples

Use recharge models with a RechargeModel stress model:

rch = ps.rch.FlexModel()
sm = ps.RechargeModel(prec, evap, recharge=rch, rfunc=ps.Gamma(), name="rch")
ml.add_stressmodel(sm)

After solving a model, the simulated recharge flux can be obtained:

rch_sim = ml.get_stress("rch")
