  1. WIS Common Alerting Protocol (CAP, X.1303) Implementation Workshop 7 – 8 April 2011, Geneva, Switzerland WMO CAP and Flood Forecasting Hydrology and Water Resources Programme WMO WMO Climate and Water Department

  2. Disaster Flood Risk mitigation: from theory to practice Flood Forecasting Extreme event Mitigated Bad land use planning and elevated exposure IWRM, IFM, Land use planning, Basin Management Lack of information and preparedness Early warnings, emergency plans, outreach and education

  3. Response to floods CFMC coordination Pre-flood Population activities During flood Alert Post-flood

  4. Flood types Riverine floods Pluvial floods Flash floods Debris and mud flows Glacial lake outburst Coastal flooding Storm surges Ground water Lake overflows Ice jams Dam failure Levee breaches

  5. FFGSFlash Flood Guidance System Joint Proposal by WMO (CHy and CBS) in collaboration with HRC, USAID and US NWS Designed to be incorporated into NMHS operations and used along with other available data, systems, tools, and local knowledge to aid in determining the near-term risk of a flash flood in small streams and basins. • Implemented in Central America as the CAFFG system (operational since 2004) • Prospectus available at http://www.wmo.int/pages/prog/hwrp/documents/FFGS4-May-2007.pdf For more information: ATyagi@wmo.int

  6. Definition FFG: Amount of rainfall of a given duration over a small basin needed to create minor flooding (bankfull) conditions at the outlet of the basin. Calculate diagnostic indices used to evaluate the potential for flash flooding Used with meteorological forecasts and nowcasts of same-duration rainfall over these basins, leads to the estimation of flash flood threat (the amount of rainfall of a given duration in excess of the corresponding flash flood guidance value) for these small basins.

  8. Community Flood Management Programme (CFMP) in South Asia: Pilot Phase (Bangladesh, India, Nepal) - WMO/GWP APFM • Implementing institutions: • Bangladesh Unnayan Parishad (BUP) Dhaka • Institute for Resource Management and Economic Development (IRMED), New Delhi • Jalstrot Vikas Sanstha (JVS), Kathmandu • Succesfully implemented and tested in the 2004 floods

  9. CFMP Pilot phase: the purposes • Assemble information on community-level coping strategies emplyed traditionally through interactions with the people • Analyze flood management activities and practices at the community level • Assess the community level and magnitude of perception of flood as a risk • Prepare a community flood management manual

  10. APFM Project Objectives: From concept to field demonstration Objective 1:To provide support for the adoption of an integrated approach to flood management Objective 2:To provide Advocacy and Capacity Building for Integrated Flood Management (Tools, Trainings, Presentation Material) Objective 3:To Provide Support for Field Demonstration Projects Objective 4:Provide Strategic advice on flood management through a HelpDesk

  11. The need for standards Sharing of hydrological data is somewhat ad-hoc, based largely on ad-hoc formats, CSV files and FTP Leads to very inefficient (or non-existent) transfer and sharing of data Sharing requires a lot of transformation effort on the behalf of the data requestor Parse different file formats Understand the concepts Metadata is often limited or non-existent, requiring follow up conversations : JAN RESERVOIR DATA 900 AM CST THU MAR 28 1985 .B JAN 0328 C DH06/HP/HW/PP/QT : STN ID POOL TAILW PCPN DISCH K CFS JSNM6 295.71 / 259.51 / 0.50 / 4.300 : BARNETT DNNM6 410.1 / 330.3 / .31 / : BAY SPRINGS L&D ABEM6 190.1 / 163.6 / .17 / : ABERDEEN L&D CBUM6 163.5 / 137.1 / .39 / : COLUMBUS L&D ARKM6 210.1 / / .07 / .650 : ARKABUTLA SRDM6 242.8 / / .10 / .250 : SARDIS ENDM6 235.1 / / .37 / .100 : ENID GRNM6 197.6 / / .70 / .100 : GRENADA BMDA4 / / 0.00 / 6.393 : BLAKELY, AR DGDA4 / / .10 / 2.634 : DEGRAY, AR NARA4 / / 0.00 / 1.244 : NARROWS, AR .END

  12. The need for harmonisation A number of initiatives exist to develop standards for water observation data: WaterML1.0, 1.1 WDTF, WOML CAP XHydro UK Environmental Agencies time series transfer format SANDRE ...; A lot of commonalities exist between the standards Partial duplication of effort Inconsistencies across the standards Hard to re-use tools Potential for a harmonised, re-usable information model Define common semantics of concepts

  13. Use of CAP for flood forecasting • Link forecasters and users • Bridging between hydrologist and disaster managers • Hydro and meteo alerts at once • Quantifying the level of risk • Making it undersatndable in different contexts • Not yet widely adopted (national standards prevail)

  14. Thank you

  15. A common situation Hydro Jack Don Need flow data! Hmm maybe Don can help… To: Jack 01/02/09, 3.2, 3, 1 01/02/09, 3.1, 3, 1 *RING RING* Hi Don, I need some upper Derwent flow readings for my geochemical model. Any ideas? Hmm, I’ve got one site. I’ll send it through… *RING RING* Ok. Got the data. Where is the site located? 10 minutes… 10 minutes… Oh, it’s at laughing jack bridge. Ummm. (papers shuffle) 147.123 -41.588 Coordinates? What reference system?? I think it’s GDA94 It’s calculated from the stream gauge reading using a rating curve.. Ok. What sensor is used? Oh…how accurate is that? Umm...... *CLICK* DON?

  16. The future? Hydro Jack Need flow data! Laughing Jack Bridge 147.123 -41.588 (AGD66) Upper Derwent River Observed properties: River level, River Flow, Rainfall • River Flow • -Measured by Sontek Acoustic Doppler Sensor (ID232) • -Accuracy: +/- 0.02 • -Installed: 01/04/2012
