Abstract: |
The steep slope along the river Rhine between the German villages of Lorch and Assmannshausen is called the "Teufelskadrich". The railway line of German federal railways and the motorway run alongside the river Rhine between the foot of the slope and the riverbank. In July 2008, after heavy rain and thunderstorms, several landslides and small debris flows occurred in the area, closing the railway line for several days. Twelve flexible ring net barriers were designed, manufactured and installed within two months as part of an emergency procedure. These lightweight ring net barriers are quick to install and are suitable for slopes with difficult access. They can also blend in with nature once installed, which was important in the "Teufelskadrich" area as the valley is a popular tourist destination. With the new barriers installed on the slope, mobilised landslide or debris flow material is drained and retained by the filtering effect of the ring net barriers. As an additional measure, some of the deposited debris has been stabilised using a slope stabilisation system, utilising high-tensile chain link mesh and soil nails. Most of the future material is thus already retained in the catchment area, further reducing erosion and limiting mass mobilisation in case of an event. |
