Optimisation of the Side Channel Compensating Measure, M8 Aue Wallbach
A branch of the Aue Wallbach was reopened as an ecological compensation measure of the Ryburg-Schwörstadt Power Plant in the autumn of 2012 and already in December 2012 it was silted up. To reduce the tendency to silt up IUB Engineering was commissioned to design a system of water structures close to the river bed (micro-groynes, S-bars) and supervise implementation. The side channel was also dredged.
Données principales
- Length of side channel 150 m
- Two natural stone micro-groynes
- S-shaped bar and groynes made from wooden piles
- Construction measures conducted from a pontoon
- Filling on the right bank and securing with root wads
- Ecological upgrade of the side channel with deadwood structures
