PREVENTIVE FLOOD PROTECTION MEASURES

Flood threatened areas

What are possible strategies for preventive flood-control?

The economic development and the urban pressure meant that bottom lands are often to be used as settlement areas.

The protection effect of structural flood mitigations like walls, dykes or flood detention constructions only works until a particular design flood. High waters beyond that flood threatened areas and causes losses. Absolute flood control does not exist.

• Flood-damage can be attenuated or even avoided with the following indi-vidual strategies: The aim of sheet precaution is to avoid the designation of building land in flood-threatened areas.
• The building precaution should minimise structural damages as a result of floods, by flood-aligned architecture and utilisation.
• The goal of the behaviour precaution is the precise acting and early warning in order to avoid losses caused by floods.
• The risk precaution is the financial precaution (insurance, reserves) in case flood damage still occurs despite the use of the aforementioned strategies.
