semi-distributed & fully distributed

Algorithm
inputs

(input data,
parameters,
model-calculated
states/storages)


  • Rain
  • Cover properties:
    • max interception



  • Rain
  • Cover properties:
    • max interception



  • Rain
  • PET
  • Cover properties:
    • max interception (OR LAI)
  • Canopy storage (state)



Canopy interception is not explicitly modelled when using daily timestep modelling.
It is implicitly considered in the ‘initial abstraction’, see infiltration & surface runoff below
