In its simplest form – without brake rings – the Geobrugg debris flow system is ideally suitable as a barrier for drift wood and rubble.This has been confirmed with other tests carried out by the Munich Technical University in Füssen/Germany.
Similar to tests with debris flow barriers, the rope forces were measured on impact and on further filling by released drift wood. Flows of between 5 and 30 m3/s were able to be covered in the tests.
