class EvapoTranspiration(TopBoundaryCondition):
    """
    Recharge provides a fixed flux boundary condition to the top layer of the
    groundwater system. Note that unlike in iMOD-WQ, there is only the option
    in iMODFLOW to apply the recharge package to the top layer.

    Parameters
    ----------
    rate: float or xr.DataArray of floats
        evaporation rate in mm/day (NOTA BENE!), dims ``("time", "y", "x")``.
    top_elevation: floats or xr.DataArray of floats
        Top elevation in m+MSL for maximal evapotranspiration strength.
    extinction_depth: float or xr.Datarray of floats
        Depth [m] in which evapotranspiration strength reduced to zero.
