Estimate Green-Ampt infiltration from HSG and optional landuse.

Adds model layers:

  • psi map: wetting front suction head [mm]

  • sigma map: soil moisture deficit [-]

  • ks map: saturated hydraulic conductivity [mm/hr]

Parameters:

  • hsg (str, Path, or RasterDataset) – Hydrologic soil group map. By default, values are reclassified with the bundled hsg_green_ampt.csv table.

  • ksat (str, Path, or RasterDataset, optional) – Saturated hydraulic conductivity map, used to derive ks (ks = ksat, in mm/hr). Required unless the reclass table already provides a ks column. The bundled hsg_green_ampt.csv has only psi/sigma, so ksat is required when using it; omitting it raises a ValueError.

  • lulc (str, Path, or RasterDataset, optional) – Land-use map used to apply infiltration modifiers. Its classes must match the index of lulc_modifier_table.

  • reclass_table (str, Path, or DataFrame, optional) – Table mapping HSG classes to Green-Ampt parameters.

  • lulc_modifier_table (str, Path, or DataFrame, optional) – Required with lulc. Table of modifier factors keyed by the land-cover class codes in the supplied dataset.

  • dual_hsg ({'native', 'drained'}, optional) – How to handle dual HSG classes, by default ‘drained’. Native dual classes must be present in the reclassification table.

  • reproj_method (str, optional) – Resampling method for reprojecting final parameter maps to quadtree blocks. By default ‘average’.
