bridget.sap_flow.sap_flow

bridget.sap_flow.sap_flow(vs, dbh, species, depths=None, bark_depth=None, sapwood_depth=None, **kwargs)[source]

Calculate sap flow from sap velocity and sapwood area.

Calculation of sap flow from sap velocity (profiles) and sapwood area (increments).

Parameters

  • vs (numpy.array, numpy.float64) – Array of (corrected) sap velocity/sap flux density

  • dbh (float) – Diameter at breast height in [cm]

  • species (str) – species name, can bei either “quercus petraea” or “fagus sylvatica” at this point

  • bark_depth (float) – Bark depth in [mm]

Returns

Q – sap flow per tree in [litres/h]

Return type

numpy.array
