Cover: A Primer on Flood ProtectionSource: BMUB

Over the past few years, extreme precipitation events in the central European region have brought about floods that have caused major economic damage. The impacts of the floods have been such that many of the affected households, companies and communities have been able to recover from them only with the help of outside assistance.

The areas affected by such extreme meteorological events have included the North Sea and Baltic Sea coastlines. Since 1962, when Germany's North Sea regions were battered by a devastating storm surge, a range of extensive technical measures have been taken, however, to protect population centres on the German North Sea coast against comparable floods. The flood protection options available to individual persons in coastal areas are very limited in comparison to the options available in inland areas. Nonetheless, the information in this brochure could still be of use for persons threatened by storm surges within receding-coastline areas (coastal sections that, in the absence of protective measures, continually change naturally) or within cities such as Hamburg and Bremen.

This primer on flood protection provides information and precise strategies that migh help prevent or reduce the harmful impacts of most of the flood events expected in the future. Its guidelines are especially relevant for owners and residents of residential buildings. In principle, however, all of the information it presents can also be applied to public and commercial areas and structures. That said, however, it must be noted that every commercial / production facility is unique, with special aspects to consider that are beyond the scope of this brochure.
