  1. National and Regional services for flood forecasting and hydrometry by Caroline Wittwer SCHAPI Hydrological adviser to the WMO Permanent Representative of France SCHAPI/Caroline Wittwer WMO RA VI – Working Group on Hydrology, 11th session – Toulouse, 25-27 March 2009

  2. 2008 : reorganization of the State A Ministry of SustainableDevelopment, including : • The previousMinistry of Ecology • In particular, the services of the former Water Directorate • Amongthem : SCHAPI, hydrometry services, 7/22 state flood forecasting local services (SPC) • The previousMinistry of Equipement • Most of the SPC • Part of the previousMinistry of Industry Visit of the Environment Agency SCHAPI/Caroline Wittwer WMO RA VI – Working Group on Hydrology, 11th session – Toulouse, 25-27 March 2009

  3. Flood Preventionreorganisation New act « loi Risques n°2003-699 » related to prevention of natural and technological risks and reparation of damage A legal framework for flood forecasting 2002 : reform of the national flood alert organization 2006 : reform of hydrometry organization SCHAPI/Caroline Wittwer WMO RA VI – Working Group on Hydrology, 11th session – Toulouse, 25-27 March 2009

  4. Artois - Picardie Seine - Normandie Rhin - Meuse Loire - Bretagne SCHAPI Adour - Garonne Rhône - Méditerranée The challenge of the FF reorganisation : Warning  Forecast Before 2002 :52 autonomous Flood Warning Units After 2005:22 Flood Forecasting Centres + SCHAPI Visit of the Environment Agency SCHAPI/Caroline Wittwer WMO RA VI – Working Group on Hydrology, 11th session – Toulouse, 25-27 March 2009

  5. SCHAPI…… • - coordinatesflood forecasting (FF)and hydrometryat national level • - produces FF vigilance map and linkitwithmeteorological vigilance map • - communicateswith national media and authorities • - supports the state local services on 24h basis • - bringstechnicaladvice to regional FF and hydrometry services (methodologies, software and equipment…) the state local services (SPC) • - produce FF local vigilance map • - communicatewith local and regionalauthorities • - produce and maintainhydrometry network SCHAPI/Caroline Wittwer WMO RA VI – Working Group on Hydrology, 11th session – Toulouse, 25-27 March 2009

  6. Water level gauges 4500 historical stations (HYDRO data base) 1500 real time stations SCHAPI/Caroline Wittwer WMO RA VI – Working Group on Hydrology, 11th session – Toulouse, 25-27 March 2009

  7. « Vigilance »Procedure at Météo France since 2001 • To better inform, thanks to a simple and summarized message that focuses on dangerous phenomena and the need to be kept informed • To improve the efficiency of the communication by “translating” the intensity of forecast meteorological parameters into a risk level • To improve anticipation and service delivered to the Civil Security Services • to broaden information dissemination SCHAPI/Caroline Wittwer WMO RA VI – Working Group on Hydrology, 11th session – Toulouse, 25-27 March 2009

  8. The vigilance procedure : crisis preparedness • To ease the management of crisis situations • Coordination between State authorities, Flood Forecasting Services and Météo-France as long as floods are on-going COGIC The National Operational Centre for Interministerial Crisis Management (Ministry of the Interior) The 7 French civil defense zones Visit of the Environment Agency SCHAPI/Caroline Wittwer WMO RA VI – Working Group on Hydrology, 11th session – Toulouse, 25-27 March 2009

  9. The Flood Vigilance System (July 2006) http://www.vigicrues.ecologie.gouv.fr Published at 10:00 AM and 4:00 PM, updated if necessary Pushed at the same time to State authorities SCHAPI/Caroline Wittwer WMO RA VI – Working Group on Hydrology, 11th session – Toulouse, 25-27 March 2009

  10. The flood vigilance system ~ 20,000 km covered by the flood State system, among the 120,000 km of >1m wide rivers • > 500 real time rain gauges and access to ~ 1200 operated by Météo-France • access to 24 meteorological radars data • ~ 1500 real time water level stations (vigicrues) • ~ 240 river sections on the flood vigilance map • concerns about 6300 towns  ~ 90% of the population living in areas likely to be flooded SCHAPI/Caroline Wittwer WMO RA VI – Working Group on Hydrology, 11th session – Toulouse, 25-27 March 2009

  11. Since December 2007 :the new meteo and hydro joint procedurethe “rainfall-flood” vigilance SCHAPI/Caroline Wittwer WMO RA VI – Working Group on Hydrology, 11th session – Toulouse, 25-27 March 2009

  12. Example – March 3rd, 2007 at 6h The meteorological vigilance map The hydrological vigilance map The new vigilance map « rainfall – flood» SCHAPI/Caroline Wittwer WMO RA VI – Working Group on Hydrology, 11th session – Toulouse, 25-27 March 2009

  13. COGIC alert SCHAPI inform COZ contacts Préfet (Prefect) SPC Maire (Mayor) public As well as internet and local websites for all Operational contacts during crisis SCHAPI/Caroline Wittwer WMO RA VI – Working Group on Hydrology, 11th session – Toulouse, 25-27 March 2009

  14. Various tools depending on anticipation • 10 days • 5 days • 3 days • 1 days • 12 hours • precipitation • EFAS • vigilance • Soilmoisture • SIM-PE SCHAPI/Caroline Wittwer WMO RA VI – Working Group on Hydrology, 11th session – Toulouse, 25-27 March 2009

  15. Various types of hydrological and hydraulical models for FF • GRs • SOPHIE • Telemac 2D • Gironde estuary • MASCARET 1D/TR • ATHYS / flash floods SCHAPI/Caroline Wittwer WMO RA VI – Working Group on Hydrology, 11th session – Toulouse, 25-27 March 2009

  16. Our parternship • About 250 receivers of flood vigilance (prefects, ministries...) • A main partner for operational production : Météo France • Scientific partners for the development of new tools (Météo France, Cemagref, Brgm, EDF, Ineris, IMFT, HSM, EMA, LTHE, EDYTEM, JRC, ...) • Technical support from the national engineering services (CETMEF and CETEs) SCHAPI/Caroline Wittwer WMO RA VI – Working Group on Hydrology, 11th session – Toulouse, 25-27 March 2009
