Field measurements used for numerical modelling of flexible debris flow barriers
A new type of debris flow mitigation measure, flexible ring-net barrier systems, are cost-effective and efficient compared to massive concrete barriers. However, the performance of these systems has not yet been investigated systematically. For this reason a wire ring-net barrier system has been installed in the Illgraben torrent, to investigate its performance, the acting forces and to provide information on the expected maintenance. Additionally, this net-testing facility allows for optimization of the structure and provides a basis for design guidelines. This paper describes the measurement facilities at the barrier and the debris flow events of 2006. First results of the filling event and their interpretation with the computational model are discussed.
