  1. Theme Natural Risk Zones Facilitator: Matt Harrison, UK Editor: Florian Thomas, France JRC Contact Point: Robert Tomas INSPIRE Conference, Edinburgh

  2. Team

  3. Presentation of the theme • D2.3 Definition: «Vulnerable areas characterised according to natural hazards (all atmospheric, hydrologic, seismic, volcanic and wildfire phenomena that, because of their location, severity, and frequency, have the potential to seriously affect society), e.g. floods, landslides and subsidence, avalanches, forest fires, earthquakes, volcanic eruptions.» 

  4. Input documents • 32 reference documents • The Floods Directive • Workcarried out by « Plan4All » • Annex I : Hydrography TWG has defined an « InundatedLand » feature class

  5. Scope • Analysis of input documents • Production of use cases • « Flood » (Cross Thematic) • « Landslide » • « Forest fire» • « Earthquake » • Codelist of 6 highlevelnaturalhazardcategories • 82 hazards (so far) • Meeting withFloods Directive working group

  6. Presentation of the theme • Risk is defined as: Risk = hazard x exposure x vulnerability. • Natural risk: • Not technological risk

  7. Presentation of the theme • Overall philosophy: « A risk zone is the spatial intersection of a hazard area with Exposed elements some of which may have increased or lowered vulnerability to this hazard  » Hazard area Risk zone Vulnerability A Exposed elements

  8. Model v2.0 • 3 packages : • 1 core package • 1 coverage package • 1 package dedicated to flood risk • Objective : • Design a genericcore model to all naturalrisks • Applyit to all types of data (vector and coverage) • As an example, applythiscore model to flood risk

  9. Model v2.0: Core package Risk zone Hazard area Vulnerability Exposedelement

  10. Model v2.0: Core package

  11. Model v2.0: Coverage package

  12. Model v2.0 Links Hazard modelling Exposed Element modelling Land use Buildings Utilities / public services Hydrology Stat. Units / Pop. distribution Administrative boundaries Geology Elevation Natural risk zones Parallel Environmental monitoring facilities Consequences on land use planning Area management Land use

  13. Model v2.0: Core package

  14. Model v2.0 : Flood Package • « Whyfloods and no otherhazard? » • Flood Directive 2007/60/CE • Overallidea: • Take the core model, eventuallyspecializeit, to makeitmeet Flood Directive’srequirements • Use the navigability of the links to avoidredundances, and the constraints to ensure the coherence of the model

  15. Model v2.0 : Flood Package Flood hazardmap Hazard area Potentialflooded area Flood riskmap Risk zone Inundated Land (AnnexI Hydrography) Preliminary flood riskassessment Exposed element

  16. Model v2.0 : Flood Package • New classes compared to the generic package : • « Potentialflooded area » : specializedfrom « hazard area » • Flood hazardmap • Flood riskmap • Preliminary flood riskassessment • « inundated land » : specializedfrom « hazard area » • Some concepts : • The « potential adverse consequences » are « exposedelements » • The « flood hazardmaps » must contain 3 flood scenarios  theycontain 3 featuresfrom the « Potentialflooded area » feat. class

  17. Open Questions • Generic Core model- useful/ useable? • More specific hazardTypescodelist? • exposedElementscodelist? • Floods Schema • Doesn’t address detailed requirements? • Can you identify how you could extend it further? • Does it demonstrate harmony between FD and INSPIRE? • More application schemas as examples? • Example implementation e.g. in major GIS software? • Geometry of risk zones / coverages Currently model vector data model and coverage separately • Portrayal rules/ guidelines • DQ & MD Chapters still require work
