- A flexible debris-resisting barrier is a structure used to mitigate debris flows or to contain flow-entrained woods. These structures mainly consist of interconnected metallic components (cables, posts, shackles...). Flexible debris-resisting barrier are derived from rockfall barriers and were first proposed in the middle of the 1990s in the USA. In torrents, flexible debris-resisting barrier constitute a sound alternative to check dams for containing debris flows. The main components of flexible debris-resisting barriers are:
* An interception structure, made up of a principal net with metallic cables, wires, and/or bars and additional layers, usually a finer mesh than the principal.
* A support structure made of metal posts, to support the interception structure.
* Connection components (also called brakes), which dissipate energy from the barrier into the ground and/or foundation. These barriers are often installed in torrents bed to intercept and contain flow-entrained granular materials or woody debris. In their simplest form, flexible debris-resisting barriers only consist of an interception structure. When installed in larger channels, the barrier also includes a support structure. (en)
