Project summary

Edit project overview to modify the project summary.


River restoration measures were implemented to improve ecological values in the area, so that these meet WFD criteria, and to connect the stream with the regional ecological structure of the valley. There are multiple aspects of large-scale stream restoration in this area:

- Flow velocity

- Summer and winter flow dynamics

- Varied vegetation banks and bed

- Removing barriers for fish

- Improving water quality

- Climatological robustness

As part of this large scale stream restoration, Building with Nature was implemented. A particular example is main channel mowing to improve channel flow.
