WflowModel.setup_ksatver_vegetation(soil_fn: str = 'soilgrids', alfa: float = 4.5, beta: float = 5)[source]#

Calculate KsatVer values from vegetation in addition to soil characteristics.

This allows to account for biologically-promoted soil structure and heterogeneities in natural landscapes based on the work of Bonetti et al. (2021) https://www.nature.com/articles/s43247-021-00180-0.

This method requires to have run setup_soilgrids and setup_lai first.

The following map is added to grid:

  • KsatVer_vegetation map: saturated hydraulic conductivity considering vegetation characteristics [mm/d]

Parameters:

  • soil_fn ({'soilgrids', 'soilgrids_2020'}) – Name of RasterDataset source for soil parameter maps, see data/data_sources.yml. Should contain info for the sand percentage of the upper layer * Required variable: ‘sndppt_sl1’ [%]

  • alfa (float, optional) – Shape parameter. The default is 4.5 when using LAI.

  • beta (float, optional) – Shape parameter. The default is 5 when using LAI.
