Model development

Substance sources and emission pathways for water pollution (Fuchs et al., 2010)
System architecture of the open source model MoRE


The Directive 2008/105/EC (on environmental quality standards) of the European Parliament and the Commission[1] asks the member states for an emission inventory of priority substances for all river basin districts. This task requires appropriate data and approaches to describe the current state of surface water bodies and to evaluate appropriate measures for the reduction of emissions into the surface water bodies. The overall aim is to achieve a good ecological state of surface waters and to comply with the quality standards.

To meet these demands, the established MONERIS nutrient emission modeling system [2], was adapted to the modeling of pollutant emissions into water bodies and implemented in an open source environment as the river basin management system MoRE (Modeling of Regionalized Emissions).

The following emission pathways are implemented in MoRE:

  • Pathways with point sources:
    • Municipal wastewater treatment plants
    • Industrial direct dischargers
    • Emissions of historic mining sites
  • Pathways with diffuse sources:
    • Erosion
    • Surface runoff
    • Tile drainage
    • Direct atmospheric deposition onto water surfaces
    • Sewer systems
    • Groundwater
    • Inland navigation

In addition to modeling emissions into the water bodies, an estimation of the river load on the basis of total emissions and a substance-specific retention is carried out. The modeling approaches and sources of input data are described in detail in Fuchs et al. (2010) [3] and Fuchs et al. (2017)[4].
