In 2008 flexible debris flow nets were developed within a three-year Ph.D. thesis by Corinna Wendeler. Since then, they have been used all over the world for debris flow protection or slope/riverbed stabilization. Some have already been filled a couple of times. Nadine Feiger did the first research on a serviceability method for scour and erosion issues on flexible debris flow nets. Design and calculation will be more economically and safely, maintenance costs will be minimized and a longer lifetime of the entire barrier system, including anchors as the most cost-intensive parts, can be provided.
