WflowSedimentModel.setup_lulcmaps(lulc_fn='globcover', lulc_mapping_fn=None, lulc_vars=['landuse', 'Cov_River', 'Kext', 'N', 'PathFrac', 'Sl', 'Swood', 'USLE_C', 'WaterFrac'])[source]#

Derive several wflow maps based on landuse-landcover (LULC) data.

Currently, lulc_fn can be set to the “vito”, “globcover” or “corine”, fo which lookup tables are constructed to convert lulc classses to model parameters based on literature. The data is remapped at its original resolution and then resampled to the model resolution using the average value, unless noted differently.

Adds model layers:

landuse map: Landuse class [-]
Original source dependent LULC class, resampled using nearest neighbour.
Cov_river map: vegetation coefficent reducing stream bank erosion [-].
Kext map: Extinction coefficient in the canopy gap fraction equation [-]
Sl map: Specific leaf storage [mm]
Swood map: Fraction of wood in the vegetation/plant [-]
USLE_C map: Cover managment factor from the USLE equation [-]
PathFrac map: The fraction of compacted or urban area per grid cell [-]
WaterFrac map: The fraction of open water per grid cell [-]
N map: Manning Roughness [-]

Parameters:

lulc_fn ({"globcover", "vito", "corine"}) – Name of data source in data_sources.yml file.
lulc_mapping_fn (str) – Path to a mapping csv file from landuse in source name to parameter values in lulc_vars.
lulc_vars (list) – List of landuse parameters to keep. By default: [“landuse”,”Cov_river”,”Kext”,”N”,”PathFrac”,”USLE_C”,”Sl”,”Swood”,”WaterFrac”]
