D-Emissions

First step in solving or mitigating many water quality and health problems, is to get a quantitative overview of the emissions of substances causing such problems. D-Emissions provides a perfect tool to assess the quantity and spatial distribution of the emitted substances in the catchment. Because it simulates the true cause-effect chain, it provides predictive power and allows for “what if” scenarios driven by policy projections and implemented measures.

D-Emissions is part of the Delft3D FM Suite which, in combination with D-Hydrology, including wflow and numerous lumped rainfall-runoff models, and D-Flow FM modules may form an integral catchment model. The D-Emissions module can however also be coupled to other hydrological models such as HYPE.

Methodology

D-Emissions makes use of relevant socio-economic drivers to spatially distribute emissions in a realistic way. Its overall methodology has been derived from the Dutch Pollutant Release and Transfer Register or PRTR (http://www.emissieregistratie.nl/erpubliek/bumper.en.aspx).

D-Emissions:

  • Is based on a ‘source-oriented approach’
  • Is based on a mass balance approach, thus avoiding double-counting or omissions of relevant emissions
  • Responds to inter-annual hydrology variations such as peak discharges during heavy rainfall
  • Is flexibility with respect to compartments, hydrological processes & models, substances, pathways and sources
  • Is embedded in the Delft3D FM Suite, which guarantees software maintenance
