“Donau Auen” National Park

This bus tour will guide you directly to the heart of the famous National Park “Donau Auen”. During a scientifically guided tour through the National Park Visitor Centre in the picturesque castle Schloss Orth the unique features of the National Park and its fascinating history will be explained. On a nature trail outside of the castle, we will have the opportunity to see indigenous plants and animals. Further, we will take a walk inside the National Park directly to the river banks of the Danube. Here, we will see some of the measures taken to improve ecological functions and sediment transport issues (e.g. restoration of river banks, reconnection of side-arms, adaptation of groynes, etc.).

New Hydraulic Laboratory

This laboratory, which has been planned and will be run by BOKU, is unique among hydraulic laboratories worldwide: with a discharge of 10.000 l/s without pumping it offers a new dimension in scale issue modelling. Experiments can be conducted in an indoor and an outdoor lab. Further, the facility provides a public lab and a big auditorium. Technical Tours will guide you through this unique facility and explain the concept as well as the experimental settings of current projects.
