Sources: point (sewage) and diffuse (agriculture, natural areas)
Main inputs: agricultural activities, sewage systems, land use, hydrology
Main outputs: river export of DIN, DON, DOP, and DIP by source and sub-basin; ICEP (Indicator for Coastal Eutrophication Potential)
Modelling approach
Figure 1: Conceptual framework of the model application to China for global change impacts. SSP is shared Socio-Economic Pathways (Wang et al., 2020). SDG is sustainable development goal (Wang et al., 2022)
