Marine ecological models will be used to track the nutrients in the sea, and trace back their riverine or oceanic sources with the transboundary nutrient transport method (TBNT). TBNT application is a prerequisite for distance-to-target requirement (DTTR) estimates. A generic watershed model applied to NEA rivers will calculate terrestrial nutrient exports to the sea under different scenarios:

  1. A past “pristine-like” scenario, where natural nutrient exports are estimated in the absence of human influence.
  2. Future “realistic” scenarios, where different urban wastewater treatments and agricultural practices are combined.

Map showing the domain of the river-basin SENEQUE/Riverstrahler model and the 3 coastal marine ecosystem models (MIRO&CO-3D, ECO-MARS3D and MOHID-LIFE) and their local implementation. The superimposed continuous line shows the 12 nm limit. Bottom right: geographical limits of the EEZ and OSPAR regions.

The river-basin model used in EMoSEM is SENEQUE/Riverstrahler (UPMC, Billen et al. 1994; Ruelland and Billen, 2005; Ruelland et al. 2007.)

The three marine ecological models used in EMoSEM are:
