pywatershed.PRMSGroundwater

class pywatershed.PRMSGroundwater(control, discretization, parameters, soil_to_gw, ssr_to_gw, dprst_seep_hru, budget_type=None, calc_method=None, verbose=None)

PRMS groundwater reservoir.

Implementation based on PRMS 5.2.1 with theoretical documentation given in the PRMS-IV documentation:

Markstrom, S. L., Regan, R. S., Hay, L. E., Viger, R. J., Webb, R. M., Payn, R. A., & LaFontaine, J. H. (2015). PRMS-IV, the precipitation-runoff modeling system, version 4. US Geological Survey Techniques and Methods, 6, B7.

Parameters:

• control (Control) – a Control object

• discretization (Parameters) – a discretization of class Parameters

• parameters (Parameters) – a parameter object of class Parameters

• soil_to_gw (Union[str, Path, ndarray, Adapter]) – Portion of excess flow to the capillary reservoir that drains to the associated GWR for each HRU

• ssr_to_gw (Union[str, Path, ndarray, Adapter]) – Drainage from the gravity-reservoir to the associated GWR for each HRU

• dprst_seep_hru (Union[str, Path, ndarray, Adapter]) – Seepage from surface-depression storage to associated GWR for each HRU

• budget_type (Optional[Literal[None, 'warn', 'error']]) – one of [None, “warn”, “error”]

• calc_method (Optional[Literal['fortran', 'numba', 'numpy']]) – one of [“fortran”, “numba”, “numpy”]. None defaults to “numba”.

• verbose (Optional[bool]) – Print extra information or not?
