RECORD Catchment – Revitalisierte Flusskorridore

The Thur catchment in North-Eastern Switzerland (Schneider et al. 2011, Hydrology and Earth System Sciences, 15(8), 2531-2549.)

In der Schweiz sollen in den nächsten Jahrzehnten Flussabschnitte mit einer Gesamtlänge von rund 4000 km renaturiert werden. Hauptziel dieser Renaturierungsmassnahmen ist die Verbesserung einer naturnahen Umwelt sowie die Erhaltung und Erhöhung der Biodiversität. Darüber hinaus bieten die daraus resultierenden vielfältigen Flussbauwerke einen besseren Schutz bei Hochwasser, während sie dem Fluss mehr Freiheit zum Ausbreiten und Bewegen lassen. Das wissenschaftliche Verständnis der zugrunde liegenden Prinzipien, die bestimmen, wie die hydromorphologische Variabilität in renaturierten Flusskorridoren mit der Funktionsweise des Ökosystems, der Biodiversität, der Grundwasserneubildung und der Grundwasserqualität zusammenhängt, ist jedoch noch begrenzt. Insbesondere der letzte Aspekt ist nicht nur für Wassermanager, sondern indirekt natürlich auch für die breite Bevölkerung von grosser Bedeutung. Der Hauptaspekt des RECORD Einzugsgebiet-Projekts, einer Fortsetzung des RECORD-Projekts (Wiederherstellung der Dynamik des Flusskorridors), bestand darin, umfassend zu untersuchen, welche Massnahmen am wirksamsten sind, um den Flusskorridor zu beeinflussen, und wie Grundwasserflusssysteme die Reaktion von Einzugsgebieten auf den Klimawandel verändern. Darüber hinaus haben wir allgemeine Schlüsselindikatoren abgeleitet, die als Grundlage für Empfehlungen für zukünftige Flussrevitalisierungsprojekte dienen können. Der Schwerpunkt unserer Forschung lag auf dem Einzugsgebiet der Thur im Nordosten der Schweiz.
