We were happy to have had the opportunity to meet with stakeholders from Viadonau, VERBUND, Amt der Oberösterreichischen Landesregierung, and University of Natural Resources and Life Sciences, Vienna (BOKU) at the BOKU River lab on March 28th to discuss the Aschach Demonstration Site (DS2).
iNNO SED's Response at DS2
Measures will be developed that improve the sediment continuity for particles smaller than fine gravel; minimize the sedimentation at the ecological structures but do not erode the structures while avoiding further accumulation and remobilization of sediment-bound pollution (sediment quality). These solutions could be upscaled to other impoundments of Upper Austria. These solutions could be upscaled to other impoundments of Upper Austria.
The iNNO SED Project and Danube Sediment_Q2 will be working together at this site to address and develop solutions to sediment continuity along impoundments in Upper Austria, with Danube Sediment_Q2 conducting essential modelling and preparatory works that will enable iNNO SED to implement suitable restoration measures.
We look forward to continued collaboration with Danube Sediment_Q2 to achieve our shared goal and ambitions!
The Danube River at Aschach is one of iNNO SED's eight carefully selected Demonstration Sites in which we aim to showcase effective and sustainable sediment management solutions.
The Problems Faced at DS2
Sediment continuity along impoundments in Upper Austria is interrupted, and sedimentation occurs. A pre-condition for ecologically oriented measures according to ecologists is that the water level is not lowered as this could lead to erosion of the structures. On the other hand, sedimentation of fine material occurs and negatively impacts or prohibits ecological benefits, including sediment quality.
