Experience and work in progress

This presentation discusses the application of GIS techniques in developing a water emission inventory in Flanders, Belgium. It covers the calculation and accounting of emissions, transportation from source to sink, and the use of gross and net emission maps. The framework allows for further development to incorporate all sources, pathways, and pollutants.

  1. Water Emission Inventory in Flanders -Belgium Experience and work in progress Meeting on PS Inventory Guidance Copenhagen, September 16-17th 2010 http://weiss.vmm.be weiss@vmm.be

  2. Contents EIW MS excel/VBA model Application of GIS techniques : Case study for the Sector ‘Buildings’ Generic framework WEISS Water Emission Inventory in Flanders -Belgium 2010 LIFE presentation 2

  3. EIW MS excel/VBA model Functional scheme

  4. EIW MS excel/VBA model Generic calculation for all sources • Point and diffuse sources • Stakeholder classification • Calculation of the Gross Emission Value (GEV) Emission Factor (EF) X Emission Explanatory Variable (EEV) • Accounting of the emissions in the different nodes of the material Flow Diagram

  5. EIW MS excel/VBA model Sources

  6. EIW MS excel/VBA model Pollutants

  7. INVENTARISEREN : lijstvan bronnen (EF, EVV) TRANSPORTEREN BEREKENEN EIW MS excel/VBA modelflow scheme

  8. Application of GIS techniques Case Study : Emissions of heavy metals generated by the corrosion of building materials LIFE presentation

  9. Zn - 2005 Gross emission map Net emission map

  10. Application of GIS techniques • 1A. Spatial distribution of the building stock • 1B. Generating gross emission maps • 2. Transporting the emissions from source to sink • 3. Accounting of the loads LIFE presentation

  11. Census entities map Land use map Dasymetric mappingalgorithm Distribution of buildings(1 map per type) Step 1A: Spatial distribution of building stock

  12. Distribution of buildings(1 map per type) GEV (Gross Emission Values) Step 1B: Generating gross emission maps Step 1A Gross emissions(1 map per metal: Cu, Zn, Pb) 2010 LIFE presentation 12

  13. Step 2: Transporting emissions from source to sink Gross emissions(1 map per metal: Cu, Zn, Pb) Accounting per flow in the Material Flow Scheme Metals per Zone A Removal in UWWTP Sewage Infrastructure map Water Treatment Areas map Overflow in Zone A Metals per Zone B Metals per Zone C Metals per ‘No Sewerage’ Net emissions (1 map per metal: Cu, Zn, Pb) 2010 LIFE presentation 13

  14. Possible pathways air soil groundwater air Source Water network and groundwater Paved and unpaved surfaces soil groundwater Private drain Sewer system Overflow removal Rainwater sewage Not linked to Individual WWTP Individual WWTP Urban WWTP Not linked to Urban WWTP Rainwater sewage Treated discharge Untreated discharge Surface waters

  15. Step 2: Transporting emissions from source to sink Gross emissions(1 map per metal: Cu, Zn, Pb) Accounting per flow in the Material Flow Scheme Metals per Zone A Removal in UWWTP Sewage Infrastructure map Water Treatment Areas map Overflow in Zone A Metals per Zone B Metals per Zone C Metals per ‘No Sewerage’ Net emissions (1 map per metal: Cu, Zn, Pb)

  16. Catchments of Flanders Municipality map Step 3: Accounting of the loads Net emissions (1 map per metal: Cu, Zn, Pb) Administrative entities Hydrological entities Any area

  17. Conclusions • EIW-model calculates emissions from source to sink • Monitoring and reporting • Scenario, planning and policy assessment • GIS introduction for a case study • Emissions of heavy metals caused by corrosion in the building stock • The strengths of both methodologies are combined in WEISS • The explicit geographical approach • The generic character of the framework and methodology allowing further development to incorporate all sources, pathways and pollutants 2010 17
