hydromt.model.Model

class hydromt.model.Model(root: str | None = None, *, components: Dict[str, Any] | None = None, mode: str = 'w', data_libs: List | str | None = None, region_component: str | None = None, **catalog_keys)

General and basic API for models in HydroMT.

Initialize a model.

Parameters:

• root (str, optional) – Model root, by default None

• components (Dict[str, Any], optional) –

  Dictionary of components to add to the model, by default None Every entry in this dictionary contains the name of the component as key, and the component object as value, or a dictionary with options passed to the component initializers. If a component is a dictionary, the key ‘type’ should be provided with the name of the component type.

  {
      "grid": {
          "type": "GridComponent",
          "filename": "path/to/grid.nc"
      }
  }
  

• mode ({'r','r+','w'}, optional) – read/append/write mode, by default “w”

• data_libs (List[str], optional) – List of data catalog configuration files, by default None

• region_component (str, optional) – The name of the region component in the components dictionary. If None, the model will can automatically determine the region component if there is only one SpatialModelComponent. Otherwise it will raise an error. If there are no SpatialModelComponent it will raise a warning that region functionality will not work.

• logger – The logger to be used.

• **catalog_keys – Additional keyword arguments to be passed down to the DataCatalog.
