Zusammenfassung
Der Beitrag zeigt, wie die Niederlande, die seit Jahrhunderten mit Flut und Hochwasser konfrontiert sind, mit der durch die Klimaveränderungen gegebenen neuen Hochwasserbedrohung in Westeuropa umgehen. Eine Besonderheit liegt darin, dass Hochwasserschutz hier nicht zuerst eine technische Angelegenheit ist, sondern eine Frage der Raumnutzung. Im Zentrum des Beitrags steht die Vorstellung des Kartenwerks über die Landnutzung und deren jeweilige Auswirkung auf den Wasserhaushalt (Waterkansenkaart). Neben Deichverlegungen und -erhöhungen, Vertiefungen und Verbreiterungen von Flußläufen werden große Wasserrückhaltegebiete auf Weideflächen geplant, gegen die sich jedoch Widerstand regt und auch alternative Vorschläge wie die für ein "Amphibisches Leben" auf schwimmenden Wohnsiedlungen hervorbringen. goj/difu
According to climatologists, the climate is changing. In the coming decades, annual rainfall in Western Europe will increase, as will water supplied by rivers. Recent flooding in Switzerland, Germany and Austria is not just an unusual incident but a call for adequate policy measures, both in the field of water management and with respect to land-use planning. This article shows how the Netherlands, a country that has been combating flooding for centuries, is dealing with its water problems. A distinguishing characteristic of the Dutch approach is that the solution to water problems is not only sought in technical measures but also in spatial measures. In land-use planning, a water opportunity map (WOM) is currently being used to outline the relationship between water and land use. In addition, the water assessment test (WAT), which presents the consequences of a plan for water systems and water management, is obligatory for land-use planning. Modern flood protection implies technical measures such as increasing the capacity of rivers by deepening riverbeds and moving dikes and/or making them higher. Retention areas for temporary relief in times of emergency have also been promoted in the Netherlands, but this has raised much opposition. Among others, from development corporations, who point at the opportunity to create floating homes. difu
