Aims and ambitions

The project developed a computer based model that can determine emission sources, map the pathway of emissions to surface waters and generate emission maps at high spatial resolution. The model will support authorities with monitoring and reporting.


A computer based model that combines emission data from diffuse and point sources with mathematical algorithms was developed. This model:

  • determines the significant emission sources and create a transparent inventory of all significant emissions, discharges and losses to water bodies caused by human activities.
  • simulates the pathways of the pollutants from sources to sinks and quantifies the importance of the flows in various nodes of the transport route.
  • generates gross (prior to treatment) and net (after treatment) emission maps at high spatial resolution (1 ha).
  • provides authorities with new methodologies and techniques that will assist in accurate estimation of sources of emissions and their contributions to the pollution of the surface waters.
  • supports authorities in their monitoring and reporting obligations and integrate the data to be collected in the framework of their mandatory reporting tasks. E.g.:
        • Water Framework Directive (WFD)
        • Urban Waste Water Treatment Directive (UWWTD)
        • European Pollutant Release and Transfer Register Regulation (E-PRTR)
        • Water Information System for Europe (WISE)
  • monitors compliance with the objectives of the Water Framework Directive to stop and decrease pollution.
  • analyses trends in emission and assist in formulating (spatially explicit) mitigating measures.
  • closes remaining gaps in the knowledge of emission of certain pollutants.
