imod.prepare.cleanup_riv(idomain: DataArray | UgridDataArray, bottom: DataArray | UgridDataArray, stage: DataArray | UgridDataArray, conductance: DataArray | UgridDataArray, bottom_elevation: DataArray | UgridDataArray, concentration: DataArray | UgridDataArray | None = None) → dict[str, DataArray | UgridDataArray][source]#

Clean up river data, fixes some common mistakes causing ValidationErrors by doing the following:

  • Cells where conductance <= 0 are deactivated.

  • Cells where concentration < 0 are set to 0.0.

  • Cells outside active domain (idomain==1) are removed.

  • Align NoData: If one variable has an inactive cell in one cell, ensure this cell is deactivated for all variables.

  • River bottom elevations below model bottom of a layer are set to model bottom of that layer.

  • River bottom elevations which exceed river stage are lowered to river stage.

Parameters:

  • idomain (xarray.DataArray | xugrid.UgridDataArray) – MODFLOW 6 model domain. idomain==1 is considered active domain.

  • bottom (xarray.DataArray | xugrid.UgridDataArray) – Grid with model bottoms

  • stage (xarray.DataArray | xugrid.UgridDataArray) – Grid with river stages

  • conductance (xarray.DataArray | xugrid.UgridDataArray) – Grid with conductances

  • bottom_elevation (xarray.DataArray | xugrid.UgridDataArray) – Grid with river bottom elevations

  • concentration (xarray.DataArray | xugrid.UgridDataArray, optional) – Optional grid with concentrations

Returns:

Dict of cleaned up grids. Has keys: “stage”, “conductance”, “bottom_elevation”, “concentration”.

Return type:

dict[str, xarray.DataArray | xugrid.UgridDataArray]
