  9. 9. 2. OBJECTIVES AND ACTIONS OF WP3
  10. 10. WP3 – OBJECTIVES & ACTIONSWP3 “Connections”• The main input for flood modelling and forecasting is rainfall (WP2): the main inputs will come from WP2• The results of WP3 are the basis for flood risk management and enhanced urban water management strategies (WP4): it constitutes one of the main inputs for WP4 WP2 WP3 WP4
  11. 11. WP3 – OBJECTIVES & ACTIONSWP 3 - Actions• A10: Adoption, customisation and automatic linkage of rainfall forecasts to pluvial flood models• A11: Improvement and customisation of models for urban pluvial flood forecasting at fine scales in each of the pilot locations.• A12: Full-scale testing of the models for pluvial flood prediction in each of the pilot locations• A13: Development of guidelines and training material for capacity building and training of future end-users
  12. 12. 4. CASE STUDIES
  13. 13. WP3 – CASE STUDIESCASE STUDY RAINFALL DATA AVAILABLE HYDRAULIC MODELSRotterdam (NL) new polarimetric X-band radar Sobek-UrbanParis (FR) new polarimetric X-band radar ?Leuven (BE) enhanced previously acquired X-band radar Infoworks and acquisition of 4 additional rain gaugesCroydon (UK) upgraded C-band radar, testing and Tuflow implementation of superresolution protocolRedbridge (UK) upgraded C-band radar, testing and Infoworks implementation of superresolution protocolOther rainfall data sources? Are the hydraulic models set up? Do they have a surface component?
  14. 14. WP3 – CASE STUDIESUK Study Site:Cranbrook catchment The drainage area of the Cranbrook catchment is approximately 910 hectares; the main water course is about 5.75 km long, of which 5.69 km are piped or culverted.
  15. 15. WP3 – CASE STUDIES The Cranbrook catchment is within the coverage area of two C-band radars: Chenies and Thurnham, operated by UK Met Office
