The interaction between a protection structure and an acting process (e.g. debris flow) has only been described in a few publications so far. In particular, the acting forces and stresses have only been measured under real conditions in a few cases. Therefore it was necessary to design a monitoring barrier that could measure both the process parameters and the forces involved and their transfer into the ground. Such a structure was built 2016 in the Gadria torrent (South Tyrol). Data has meanwhile been measured, recorded and evaluated from five debris flows. With flow heights up to 2 m, densities up to 2,200 kg/m3 and velocities between 1 and 6 m/s, the measured impact forces could be compared with the existing loading approaches. The findings serve as a basis for the improvement of approaches for the design of protection structures.
