Enns - Aich
Key features of the case study
As part of the “flood protection programme for the Upper Enns River” ecological orientated measures were implemented at the river Enns in the village Aich. Besides several technical measures like a flood protection dam the river bed was widened in two sections both as retention area and for ecological benefits. Bank stabilization structures were removed and for this reason lateral erosion increased and the development of gravel bars was initialized. A new side arm was created which offers diverse instream structures and many different habitat types.
