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). bottom_elevation: float or xr.DataArray of floats is the bottom of the riverbed (RBOT). conductance: float or xr.DataArray of floats is the conductance of the river. density: float or xr.DataArray of floats is the density used to convert the point head to the freshwater head (RIVSSMDENS). concentration: "None", float or xr.DataArray of floats, optional is the concentration in the river. Default is None. save_budget: bool, optional is a flag indicating if the budget should be saved (IRIVCB). Default is False.
