Action Plan on Floods – Why?

December 1993 Cities flooded: Germany, The Netherlands

Jan./Feb. 1995Cities flooded: Germany,The Netherlands, twohundred thousandpeople evacuated

4 February 1995 Declaration of Arles: Mandate for the flood action plan

Koblenz – Deutsches Eck -Situation in 1993 and 2005

Rhine Ministers’

Conference January 1998

Rotterdam

Decision:

Implementation of the flood action plan

Action Plan on Floods

GoalImproving the protection of people and property against floods

while

integrating ecological improvements of the Rhine

Action Plan on Floods

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

(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

Action Plan: inrease flood awareness

10,7 million people

are concerned by floodin these flood risk areas

The lives of

5,5 million people

are at risk during floodswith a depth of waterabove 2 m

Potential damage

~ 165 billion €

Implementation

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

an economicimperative!

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 emercencyresponse 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, natureprotection

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

(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?
