Initial situation

In Lienz/Altstätten in the Swiss Rhine Valley, about 50 buildings are at risk from floods and debris flow.
A bedload study showed that smaller debris flows above the Roti Platte area (starting area of the debris flows) can detach in the gullies, which can grow into a larger debris flow in the Roti Platte area. They can mobilize up to 10,000 m³ of additional material between the Roti Platte area and the Furnis barriers.

Description

The construction project comprises two staggered net barriers (VX160-H6) in the Roti Platte area with a retention volume of approx. 1600 m³. These net barriers, which are planned as transitional measures until the expansion project further downstream, are intended to interrupt the growth of a debris flow and to increase the protection of the village of Lienz.
