The goal of this work is to implement and improve protection against floods
Heavy rain events in the Alps in the years of 1999, 2005 and 2013 led to major floods and substantial financial damage in the South of Germany. Such events are likely to increase with climate change. Furthermore, balancing societal and ecological priorities as well as working to remodel the densely populated inner city to implement the river restoration plan was challenging, with disagreements over the design in certain areas as well as what was feasible within the confines of the city.
The Isar river restoration along 8 km in the city of Munich is a spectacular achievement in its ability to accommodate both large floods that regularly... more
In order to be able to implement the measures for the implementation of the EU Water Framewor Directive and to achieve an ecological improvement along the Günz a water development concept was drawn up. The main objectives are to restore the linear passability of watercourses, to enable self-dynamic development of the river, to improve the structure of the water body and to re-establish the connection of the Günz with the floodplain.
In Deisenhausen structural measures to improve the ecological situation were taken, especially to protect the fish species Common nase. The measures have been coordinated and developed in close cooperation with... more
The Zorrotzaurre project is an urban renewal project to promote the sustainable restoration of a currently derelict site in the Zorrotzaurre peninsula, northwest of the city centre. The plan is to create a new quarter that is well-connected to the rest of the city, with affordable housing, environmentally-friendly business areas, social and cultural facilities, and spacious green areas for recreation. The Master Plan was designed by the architect Zaha Hadid, and includes the conversion of the current Zorrotzaurre peninsula into an island by opening up the Deusto Canal. The plan foresees a total surface of 673 000 m2 and includes flood... more
"Testing the feasibility of a green infrastructure, instead of a traditional grey infrastructure, to treat sewage overflows, and investigating the multiple benefits that the green infrastructure provides and its relevance for water management." Potential impacts/benefits: - Improved management of water resources for the benefit of people and biodiversity. - Providing evidence that green infrastructures, besides complying with the existing water regulations, provide additional services. - Providing the regional government, the main sponsor of the infrastructure, with a cost-benefit analysis that can be replicated to analyse the potential... more
Between 1999 and 2005 the municipality of Dirlewang experienced 6 greater flood events, what caused damaged amounting millions. To prevent further damage a flood control reservoir was built. In the course of this the district of Schwaben also restored a 3 km long section of the Mindel. In this former canalized area, the Mindel can develop into a near-natural watercouse again.
The Eggstätt-Hemhofer-Lake District was designated in 1939 as one of the first Bavarian nature reserves. The Seeoner Seen nature reserve followed in 1985. Even then it was clear that both protected areas were too small for themselves to ensure the long-term survival of numerous animal and plant species. The Ischler Achen with its tributary waters and adjacent habitats is being developed as the core structure of the biotope network. A network of ecologically upgraded areas is to provide additional habitat for endangered species throughout the lakes' catchment area. During the first phase of the project, the focus was on the maintenance of... more
With 24 dam power plants, the Lech is the most densely used river in Bavaria. Its original floodplains with their typical flora and fauna have disappeared. Only a few areas, mostly near-natural, have remained, including the Litzauer Schleife south of Schongau. But here, too, natural processes have been disrupted: the construction of the Forggen lake dam has cut off the transport of sand, gravel and boulders (so-called bedload) from the Tyrolean Lech. Strong flood events hardly ever occur anymore due to the strong regulation of the water level. Within the framework of the project, the association Lebensraum Lechtal will carry out measures... more
Just under 1.5 hectares of the raised bog area are currently being restored to a halfway original state by thinning out the woods - with the consent of the five owners of the site who are foregoing firewood in favor of nature. This "raised bog restoration" is being carried out in consultation with the District Office (Lower Nature Conservation Authority) and the Government of Upper Bavaria under the expert guidance of Dr. Helmut Hermann.
Over the years, a gravel bank between the Loisach and the Kochelsee was piled up due to wave action. To reconect the Altwasser to the Kochelsee the gravel was removed and the old river bed of the Loisach was restored. This allows fish to spawn and live in the old water again.
