Flexible ring net barriers against debris flow have been installed worldwide during the last 10 years mainly for the purpose of debris retention and a few as erosion control. An increasing number of client projects (40 barriers within Switzerland, more than 100 worldwide by 2017) shows the interest in this solution. This article highlights different special applications such as one single barrier providing a very large retention capacity, an example of several barriers in line and filled up barriers for erosion control. Advantages and challenges for the use of flexible ring net barriers are discussed on a technical and economic level and needs for maintenance and replacement works are addressed.
