Flood protection Lohningstein ditch Zell am See

The torrent control at the Lohningsteingraben in Zell am See was created together with the torrent and avalanche control – WLV Salzburg in the course of Christoph Mösl’s diploma thesis.

The task was to assess the potential sediment load and to design a suitable filter structure for it. The filter structure has a length of 50m, a height of 10m and a wall thickness of 1.0m. The structure is capable of separating around 1000m³ of sediment from the water. Due to the construction of this structure, the Red Zone (no-build zone) along the Lohningstein Ditch could be reduced to a minimum.
