FFGSFlash Flood Guidance System
• 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
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.
For more information: [email protected]

Definition
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.
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

Community Flood Management Programme (CFMP) in South Asia:
• Succesfully implemented and tested in the 2004 floods
Implementing institutions:•Bangladesh Unnayan Parishad (BUP) Dhaka•Institute for Resource Management and Economic Development (IRMED), New Delhi•Jalstrot Vikas Sanstha (JVS), Kathmandu
Pilot Phase (Bangladesh, India, Nepal) - WMO/GWP APFM
![Page 10: WMO Climate and Water Department WMO WIS Common Alerting Protocol (CAP, X.1303) Implementation Workshop 7 – 8 April 2011, Geneva, Switzerland Hydrology.](https://reader036.fdocuments.in/reader036/viewer/2022062417/551544975503465e608b61f5/html5/thumbnails/10.jpg)
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
![Page 11: WMO Climate and Water Department WMO WIS Common Alerting Protocol (CAP, X.1303) Implementation Workshop 7 – 8 April 2011, Geneva, Switzerland Hydrology.](https://reader036.fdocuments.in/reader036/viewer/2022062417/551544975503465e608b61f5/html5/thumbnails/11.jpg)
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

The need for standardsThe 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

The need for harmonisationThe 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
![Page 14: WMO Climate and Water Department WMO WIS Common Alerting Protocol (CAP, X.1303) Implementation Workshop 7 – 8 April 2011, Geneva, Switzerland Hydrology.](https://reader036.fdocuments.in/reader036/viewer/2022062417/551544975503465e608b61f5/html5/thumbnails/14.jpg)
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)

Need flow data!
Hmm maybe Don can help…
*RING RING*
Hi Don, I need some upper Derwent flow readings for my geochemical model. Any ideas?
Don
Hmm, I’ve got one site. I’ll send it through…
10 minutes…
To: Jack01/02/09, 3.2, 3, 101/02/09, 3.1, 3, 1
10 minutes…*RING RING*
Ok. Got the data. Where is the site located?
Oh, it’s at laughing jack bridge.
Coordinates?
Ummm. (papers shuffle)147.123 -41.588
What reference system??I think it’s GDA94
Ok. What sensor is used?It’s calculated from the stream gauge reading using a rating curve..
Oh…how accurate is that?
Umm......
DON?
