FEMMA outputs

With FEMMA we can calculate outputs in annual, seasonal, daily or shorter time scale.

Hydrology:

  • Runoff
  • Water balance components for the entire catchment, a forest compartment or a specific location in the catchment

Runoff quality:

  • Nitrate load and concentration in the outlet
  • Ammonium load and concentration in the outlet
  • DON load and concentration in the outlet

 Nitrogen balance:

(ammonium, nitrate and DON) for the entire catchment, a forest compartment or a specific location in the catchment:

  • Deposition
  • N release in decomposition
  • N uptake by trees
  • N uptake by ground vegetation
  • N immobilisation into microbes
  • Nitrification
  • Denitrification
  • N2O outflux in nitrification
  • N sorption in soil
  • N transport in groundwater and surface water
