hydromt_wflow.WflowModel.setup_glaciers

WflowModel.setup_glaciers(glaciers_fn='rgi', min_area=1)

Generate maps of glacier areas, area fraction and volume fraction.

Also generates tables with temperature threshold, melting factor and snow-to-ice convertion fraction.

The data is generated from features with min_area [km2] (default is 1 km2) from a database with glacier geometry, IDs and metadata.

The required variables from glaciers_fn dataset are glacier ID ‘simple_id’. Optionnally glacier area ‘AREA’ [km2] can be present to filter the glaciers by size. If not present it will be computed on the fly.

Adds model layers:

• wflow_glacierareas map: glacier IDs [-]

• wflow_glacierfrac map: area fraction of glacier per cell [-]

• wflow_glacierstore map: storage (volume) of glacier per cell [mm]

• G_TT map: temperature threshold for glacier melt/buildup [°C]

• G_Cfmax map: glacier melting factor [mm/°C*day]

• G_SIfrac map: fraction of snowpack on top of glacier converted to ice, added to glacierstore [-]

Parameters:

• glaciers_fn ({'rgi'}) –

  Name of data source for glaciers, see data/data_sources.yml.

  • Required variables: [‘simple_id’]

• min_area (float, optional) – Minimum glacier area threshold [km2], by default 0 (all included)
