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


  • Rain
  • PET
  • Cover properties:
    • LAI
    • canopy interception coefficient
  • Canopy storage (state)
Function
type 		exponential & threshold exponential & threshold threshold threshold
Thresholds

yes:
timestep interception capacity (calculated)

yes:

Infiltration into soil moisture (SM)

Surface water generation of landscape units

Surface runoff to channel network

Evapotranspiration (ET) from soil moisture (SM)

Evapotranspiration (ET) from groundwater (GW)

Interflow generation & routing to channel network

Aquifer recharge

Groundwater (GW) flow

Aquifer exchange with channel: aquifer outflow or channel transmission losses
