Protection against floods: the innovative
cable weir in the Rienza gorge
Relationship between man, mountain and technology
Every year, in Alpine regions like South Tyrol, numerous measures are taken to secure mountain streams. In recent times, experts are concentrating most on the issue of wooden debris. This is because just a few tree trunks are all it takes to block a bridge or cause an obstruction. This, in turn, can cause serious flooding.
Good Practice: The cable weir in the Rienza gorge
The Rienza springs at the feet of the Tre Cime of Lavaredo, in the Municipality of Dobbiaco. It then runs through Val Pusteria and into the Rienza gorge in Brunico. To the inhabitants of Brunico, the gorge is an important place for relaxation and an easily reached tourist destination. In addition to hikers, the gorge also attracts many water sports enthusiasts. For the territory of Brunico, one of the main problems is the wooden debris transported by the Rienza. Following obstructions, the city has often been subjected to large floods (the last dating back to 1998).
For this reason, a search was made for a solution that could be efficient and, at the same time, integrate in a non-invasive manner in the natural environment. A decision was therefore made to proceed with the first - and so far only - cable weir in the whole of South Tyrol. Construction work was carried out from April 2012 to June 2013.
