Flexible ring net barriers for retaining debris flow

• enormous reduction in construction time
• cost-savings of 30 to 50 % compared to concrete structures
• environment-friendly solutions, adapting visually into the landscape
• tested in field trials with the Swiss Federal Research Institute for Forest, Snow and Landscape WSL 
• single-level barriers for events of up to 1’000 m³, multilevel barriers for events of several 1’000 m³

Wide range of applications:

• Individual barrier for retaining minor debris flows
• Multilevel debris flow barrier for retaining larger debris flows
• Debris flow breakers for braking the debris flow front
• Protection against the blocking of passages
• Drain-off element of a rubble collector
• Diversion structure for correcting the channel course 
• Protection against scouring and erosion
• Protecting the channel flanks against erosion
