hydromt_wflow.WflowModel.setup_lakes#

WflowModel.setup_lakes(lakes_fn='hydro_lakes', min_area=10.0)[source]#

This component generates maps of lake areas and outlets as well as parameters with average lake area, depth a discharge values.

The data is generated from features with min_area [km2] (default 1 km2) from a database with lake geometry, IDs and metadata. Data required are lake ID ‘waterbody_id’, average area ‘Area_avg’ [m2], average volume ‘Vol_avg’ [m3], average depth ‘Depth_avg’ [m] and average discharge ‘Dis_avg’ [m3/s].

Adds model layers:

  • wflow_lakeareas map: lake IDs [-]

  • wflow_lakelocs map: lake IDs at outlet locations [-]

  • LakeArea map: lake area [m2]

  • LakeAvgLevel map: lake average water level [m]

  • LakeAvgOut map: lake average discharge [m3/s]

  • Lake_b map: lake rating curve coefficient [-]

  • lakes geom: polygon with lakes and wflow lake parameters

Parameters:

  • lakes_fn ({'hydro_lakes'}) –

    Name of data source for lake parameters, see data/data_sources.yml.

    • Required variables: [‘waterbody_id’, ‘Area_avg’, ‘Vol_avg’, ‘Depth_avg’, ‘Dis_avg’]

  • min_area (float, optional) – Minimum lake area threshold [km2], by default 1.0 km2.
