Protection Systems Against Debris Flows

This paper describes how debris flows are natural hazards that look like a combination of flood, land and rock slide. The phenomenon is also called mud or debris avalanche because similar flow behavior is compared with snow avalanches. Debris flows regularly cause severe damages in mountainous areas like the Alps. Like rock fall, the debris flows loads act mainly on a protection barrier. But in contrast to falling rocks, debris flows are not punctual impacts but a distributed load on the protection system. A further difference between the two hazards is the fact that rockfalls are single events while debris flows mostly occur in surges. Experiences from North America, Japan and Europe prove that flexible protection systems like the Geobrugg VX/UX Systems have an ideal bearing behavior to stop dynamic loads such as debris flows because of their large deformation capacity
