Inn, Flood Protection Schärding

The border town Schärding, at the Pram’s confluence to the Inn is frequently subject to flooding. The reason for the partially extreme high water levels within the city limits is the Vornbacher narrowing, a deep river-valley between Passau and Schärding, which causes a back-up all the way to Schärding because of the limited discharge capacity.

Objective of the feasibility study was the preparation and side-by-side comparison of diverse solution approaches and demonstrating a technical and economically feasible suggestion. The city-area is divided into five independent project segments.

The primary protection measure would be the erection of dams. Implementation of walls with mobile components as well as utilization of existing walls and masonry is planned for certain segments.
