The city is developing strategies to:<ul><li>Protect the most vulnerable groups of the urban population (elderly people, homeless people, children in age up to 6 years, lonely living pensioners, etc.);</li><li>Minimise the carbon footprint of the city– housing/building, transport, waste treatment;</li><li>Implement green and soft adaptation measures to maximise the use of rainwater and green infrastructure.</li></ul>City actions have been intensified by implemented activities and projects – also thanks to international grants funding:<ul>
As the fourth most water-rich river in Germany, the Inn was used for energy production at an early stage. 14 hydroelectric power plants in the German section of the river impair the passability for fish. In addition, the Inn was straightened, expanded and dammed for land reclamation, shipping, flood protection and energy production, thus losing its natural dynamics. Within the framework of the Inn River Development Plan, bypass channels for fish migration, flood troughs for flood protection and biodiversity and new alluvial forest were created.
The measures are part of the implementation concept <em>Untere Alz</em> of the European Water Framework Directive and aim to enable the natural development of the river Untere Alz. Therefore the bank protection has been removed on 1700 meter lenght. Furthermore ten backwaters as habitats for fish and amphibians have been created and structural measures (e.g. implementation of deadwood) have been implemented.
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.
Section 1 concerns the area immediately below barrage 23.The power plant represents a barrier for water organisms, which is why the continuity is to be achieved with the aid of a fish bypass. The possibility of flooding the floodplain forest via the Fischbach can contribute to the vitalization of the floodplain. At the moment, it is largely cut off from flood events by the strong deepening of the river Lech. On the eastern side of the Lech there is the opportunity to remove the bank protection so that the river can successively break up the bank.
Between the two world wars the Isen was developed and regulated according to purely technical aspects. The course of the river was straightened, the meandering arches were punctured and cut off. Many of these former river loops were filled in and only a few remained as old water. To improve the ecological situation and the flood protection additional flood retention areas were created, the gradient was reduced and the flowline was extended.
The second section is similar to the first. The existing crash structure is to be removed to allow a self-dynamic development on the western side of the river. For this purpose, the river bank protection must be removed. In contrast to the first section, the foreland width in section 2 is only about 80 m. Since there is not enough space for a self-dynamic development, a comprehensive dike relocation is aimed for. This will mobilize additional bedload reserves, give the river more open space and connect large areas of floodplain forest to the Lech.
Due to the close proximity to the community of Kissing on the eastern side of the Lech river and the wells to Drinking water production on the west, the developmental possibilities in this section of the Lech are limited. Therefore, necessary measures for the nature-compatible protection of the river bed (e.g. rough ramps) should be bundled here. The aim is to create the conditions for a free development in sections 1 and 2. A design of the river bed as close to nature as possible is aimed for in this section by widening on the eastern side.
As in section 3 of the Licca Liber project, a dynamic self-development of the Lech is also conceivable in section 4. This should take place either on the west or east bank. The respective other bank section will be designed close to nature. Below the crash structure at river kilometre 50.4 the deepening of the river Lech is the greatest. Therefore, at this point sole-supporting measures such as a rough ramp are necessary to raise the river bed to the 1999 level (before the flood). The handling of the fall structure at river kilometre 50.4 remains uncertain until the detailed planning.
In section 5 of the Lech river only structure improving measures within the existing Water profile are planned. The section is located in the backwater area of the high-discharge system. The flow velocities in this area are strongly reduced, which is why a self-dynamic development and natural watercourse design are not very promising.The measures are part of the project Licca Liber.
