hydromt_sfincs.workflows.horton_from_hsg(da_hsg: DataArray, df_map: DataFrame, *, da_ksat: DataArray | None = None, dual_hsg: str = 'drained') → Dataset[source]#

Estimate Horton parameters from HSG classes and optional Ksat.

Reclassifies kd and either fc/f0 or fc_scale/f0_scale. If Ksat is supplied, it determines fc and the optional fc_scale is applied. Inputs must already be-read xarray objects and a DataFrame.

Parameters:

  • da_hsg (xr.DataArray) – Hydrologic soil group class raster.

  • df_map (pd.DataFrame) – Horton parameter table indexed by HSG class.

  • da_ksat (xr.DataArray, optional) – Saturated hydraulic conductivity raster [mm/hr] used to derive fc.

  • dual_hsg ({"drained", "native"}, optional) – HSG normalization mode, by default "drained". Native dual-HSG classes require corresponding rows in df_map.

Returns:

Horton f0, fc, and kd rasters.

Return type:

xr.Dataset
