The flood of August 2005 represents a unique event in the context of recent history. However, it is not unique in historical terms.
Thus major supraregional hazard events must also be expected in the future. The consistent pursuit of a comprehensive flood protection policy is essential to prevent similar or worse damage than that which arose in 2005 from occurring again: the unimpeded spread of hazard potential must be prevented through careful land use. Thus, flood protection policy remains an ongoing task which concerns not only the experts but must also and increasingly involve the entire population.
