Pollutants: dissolved inorganic (DIN) and organic (DON) nitrogen (N)
Sources: point (sewage) and diffuse (agriculture, natural areas)
Main inputs: agricultural activities, sewage systems, land use, hydrology
Main outputs: river export of DIN, and DON by source and sub-basin
Modelling approach
Figure 1: Conceptual framework of the model application to the world
Model outputs (example)
Figure 2: Changes in river export of total dissolved nitrogen between 2010 and 2050 according to a scenario assuming low policy ambitions in agriculture, high economic development and a lot of global warming (the combination of Shared Socio-economic Pathway 5 and Representative concentrative pathway 8.5). The scenario is developed in the INMS project and implemented to the MARINA-Nutrients model (Maryna Strokal, Mengru Wang, et al. under development).
