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:
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:
A detailed description of the project's workpackages is available.
