impact of a tree onto a flexible rockfall barrier. Normally, the flexible rockfall protection systems available on the mar-ket are tested only for the rockfall load case according to the Swiss (Gerber, 2021) or European (EOTA, 2021) guidelines. However, barriers installed in the field are often subject to loads other than rockfall such as

Rockfall Barriers, Fencing & NettingAustralia Wide

Rock catch fences provide stand-alone protection whilst rockfall mesh needs to be molded to the rock. This requires an experienced team in often very steep and dangerous terrains to install correctly and guarantee durability. Rock catch fences are used when fall conditions are unpredictable but still require security and safety measures.

DESIGN OF FLEXIBLE DEBRIS FLOW BARRIERS

that are commonly used for rockfall protection. To apply flexible barriers to debris flow, several ques-tions require answers What are the debris flow loads? How does the barrier perform during the filling process? What are the physical limits for the investigated barriers? Focussing on these questions a load model is presented that allows the design of flexible barriers for debris flows.

The aim of this analysis is the enhancement of maximum energy capacity of the barrier related with the amount of material used to build it. Following the ETAG recommendation, the maximum energy level (MEL) test is achieved if the barrier is able to retain the block. Thus, the MEL level for each numerical model was determined by increasing the initial speed of the block until it trespasses the barrier.
