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.
