Flood Forecasting and Early Warning System Workshop


Flood forecasting sequences need 24 24 operations

Flood Forecasting sequences : need 24/24 operations

Initialised at To then Runs every Tf (to be parameterised)

Data collection from NIMH when available before Time T; interfaces to be set

Data coherence analysis on retrieved data to be defined and designed

Process data assimilation : “mix” observations with results from last computation

Run the models at time T using initial conditions from data assimilation

Provide results at node points defined as output discharges / water heights

Flood Forecasting and Early Warning System Workshop


The flood forecasting platform user need analysis

The Flood forecasting platform : user need analysis

Provide results at node points to be defined as output

Results may be discharges / water heights

Interfaces to be defined /designed in the project

Threshold values (for alarms / alert levels) can be set and parameterised

Specific outputs as bulletins for Alarm dissemination to be defined

Flood Forecasting and Early Warning System Workshop

Decision to warn

Flood Forecasting and Early Warning System Workshop


Flood warning system first level without ffs

Flood Warning system : First level without FFS

  • Continuous comparison of rain & river data to threshold values

  • If thresholds exceeded, data bulletins are:

    • Manually or Semi-Automatically generated

    • Semi-Automatically disseminated

RIVER HEIGHT BULLETIN for Herbert, Tully, Johnstone, Barron & Daintree Rivers

Issued at  3.30am on Tuesday, 15 March 2005

Flood Forecasting and Early Warning System Workshop


Flood warning system level 2 with ffs

Flood Warning system : level 2 with FFS

  • Analysis & prediction

  • If warnings are deemed necessary, they are:

    • Prepared manually / automatically

    • Automatically disseminated

st

Flood Forecasting and Early Warning System Workshop


Flood warning framework to be discussed

Flood Warning Framework to be discussed

  • Hydro-Meteorology services role should be to forecast flood height.

  • Basin Directorate’s role should be to forecast flood extent, especially for urban inundation.

  • Exchanges with Turkey to be defined

  • Roles and responsibilities to be analysed

Flood Forecasting and Early Warning System Workshop


Warning dissemination who

Warning dissemination – Who ?

  • Emergency Services

  • Police

  • Local Agency

  • Media

    • Radio

    • Television

    • Newpaper

  • Web

  • Flood Forecasting and Early Warning System Workshop


    Warning dissemination how

    Warning dissemination – How ?

    • Warning products issued via:

      • Telephone

      • Fax

      • Email

      • SMS

      • Computer Messaging Service

    • Direct briefing to:

      • Local Government

      • Emergency Services

      • Media

    Flood Forecasting and Early Warning System Workshop


    Discussion analysis of user need organisation and information flux

    Discussion : analysis of user need, organisation and information flux

    User needs for designing the Flood forecasting platform:

    Will be analysed during the next steps of the project (january 2008)

    Will include interfaces to be defined and implemented during the FFS design

    Threshold values for alarms / alert levels : details should be provided for the next workshop (spring 2008)

    Organisation of the Flood warning framework : who does what ?

    The responsibilities of the various stakeholders and operators ?

    Specific outputs as bulletins for Alarm dissemination to be defined : what are the expectations ?

    Interfaces with Turkish authorities : what is expected

    Flood Forecasting and Early Warning System Workshop


    Flood forecasting system and flood warning operations

    Roles and responsibilities during flood events

    Turkey crisis centre

    Receive flood warnings & observed and forecasted data

    • Institute of Meteorology

    • Operates the forecasts 24/24 during the crisis

    • Alerts the regional basin crisis centre of evolutions

    • Provides forecasted data

    National crisis centre

    Coordinates flood disaster response

    Regional Basin crisis centre

    Issues flood warnings and forecasts

    Issues river heights bulletins / info

    Prepares / uses flood maps

    Regional crisis centre

    Coordinate local actions of flood mitigation

    Local Government crisis centre

    Coordinate regional actions of flood mitigation

    Implement local disater plans

    Provide local advices and recommendations

    MEDIA

    Broadcast information / bulletins

    COMMUNITY at RISK

    Acts on advices and warnings
