Dike break near Fischbeck at the Elbe river:

o Reason: Sliding of inner and outer slope and lowering of the crest

o Overtopping of the dike at that reach

o Discharge at the beginning: > 500 m³/s

o Overall water flowing inland: 225 Mio m³

o Inundated area: 150 km²

o Evacuated people: > 9,000

Decision making process – responsibilities in the German emergency management system

County level: emergency management during “ordinary disasters”

State level: emergency management during state-wide disasters

Federal level: support of emergency management by resources and

technique (f.e. armed forces)

Questions of emergency management forces in the case of a large dike break (Fischbeck case):

- What area will be affected by inundation?

- What water levels have to be expected?

- What is the dynamic of the process?

- What will be the influence to emergency management

measures (evacuation routes etc.)

16

Example for a dike failure scenario

Assumption of the dike breach length: 100 m

Results after:

a.) 3 hours

b.) 6 hours

c.) 12 hours

d.) 24 hours

e.) 48 hours

Decision making process - challenges

- Different types of disasters (flooding, fire …)

- small and large scale disasters

- Involvement of specific knowledge necessary

- situation in the disaster region is influenced by a lot of

measures:

- Emergency management measures

- Actions taking by the people

Information level of the decision makers?!
