    Implementation of the flood action plan

    Action Plan on Floods

    Goal Improving the protection of people and property against floods


    integrating ecological improvements of the Rhine

    Action Plan on Floods

  • 8

    Action targets:

    (1) Reduce damage risks

    (2) Reduce flood levels

    (3) Increase awareness of floodings

    (4) Improvement of flood forecasting

    Action Plan on Floods

    (1) Reduce damage risks

    no increase until 2000

    reduction up to 10% by 2005

    reduction up to 25% by 2020

    (2) Reduce extreme flood levels (downstream from Baden-Baden)

    by 5 cm by 2000

    by up to 30 cm by 2005

    by up to 70 cm by 2020

    Action Plan on Floods – targets

  • 9

    (3) Increase flood awareness

    by drafting risk maps of the entire inundation areas and the flood-prone areas by 2005

    (4) Improve flood warning systems and prolong forecasting periods

    by 50 % by 2000

    by 100 % by 2005

    Lower Rhine ~20 billion €

    Rhine delta ~131 billion €

    Total damage sum:

    ~ 165 billion €

    Action Plan: inrease flood awareness

    10,7 million people

    are concerned by flood in these flood risk areas

    The lives of

    5,5 million people

    are at risk during floods with a depth of water above 2 m

    Implementation of the Action Plan on Floods

    River Rhine:

    Potential damage

    ~ 165 billion €


    of the flood action plan (12,3 billion €) is essential –

    an economic imperative!

    Purpose of the Rhine atlas

    �Raise the population‘s awareness for flood risk

    �Inform on extent of damage in order to be able to justify and implement measures

    �The atlas is meant as an incentive to draft more precise maps for regions and towns, for civil protection, for civil emercency response groups such as fire brigades etc.

    Action Plan on Floods: measures

    Reduce extreme flood levels �Construct artificial water retention schemes along the main stream, where possible, relocate dikes, etc.

    �Re-nature streams

    �De-intensify agriculture and forestry

    �Simultaneously: co-operate with spatial planning, agriculture, forestry, nature protection

    Reduce damage risk

    Action Plan on Floods: measures

    - Land use control (e.g. open areas, guidelines for spatial planning)

    - Precautionary construction (e.g. flood-compatible construction, no oiltanks and electric installations in basements, flood doors etc.)

    - Flood preparedness (Protection for persons, information on correct behaviour, evacuation of areas at risk)

    - Hazard preparedness (emergency measures, emergency spillways, financial preparedness through insurances)

    Implementation of the flood action plan 2000-2005-2020

    First Report by 2000: 2001: adopted by 13th Conference of Rhine Ministers

    �Damage risks -

    �Reduction of flood levels ����

    �Flood risk maps ����

    �Flood forecasting ����

    Second Report on the implementation by 2005

    (in prep.)

  • 15

    (1) Damage risks – even higher?

    (2) Reduction of flood levels by up to 30 cm?

    (3) Flood risk maps (main stream and some tributaries)

    (4) Flood forecasting (doubling lead time for different Rhine stretches)

    Implementation of the Action Plan on

    Floods – Results by 2005?
