imod.flow.River

class imod.flow.River(conductance, stage, bottom_elevation, infiltration_factor)

The River package is used to simulate head-dependent flux boundaries. In the River package if the head in the cell falls below a certain threshold, the flux from the river to the model cell is set to a specified lower bound.

Parameters

• stage (float or xr.DataArray of floats) – is the head in the river (STAGE), dims ("layer", "y", "x").

• bottom_elevation (float or xr.DataArray of floats) – is the bottom of the riverbed (RBOT), dims ("layer", "y", "x").

• conductance (float or xr.DataArray of floats) – is the conductance of the river, dims ("layer", "y", "x").

• infiltration_factor (float or xr.DataArray of floats) –

  is the infiltration factor, dims ("layer", "y", "x"). This factor defines the reduces the conductance for infiltrating water compared to exfiltrating water:

  cond = A / (c * iff)

  where A [L2] is the area where surface water and groundwater interact, c [L] is the resistance, and iff is the infiltration factor.

  The infiltration factor is thus equal or larger than 1.
