Abstract. Flexible barriers are being increasingly applied to mitigate the danger of debris flows. However, how barriers can be better designed to withstand the impact loads of debris flows is still an open question in natural hazard engineering. Here we report an improved large-scale physical modelling device and the results of two consecutive large-scale granular flow tests using this device to study how flexible barriers react under impact from granular flows. In the study, the impact force directly on the flexible barrier and the impact force transferred to the supporting structures are measured, calculated and compared. Based on the comparison, the impact loading attenuated by the flexible barrier is quantified. The hydro-dynamic and hydro-static approaches are also validated using the calculated impact forces.

Short summary
This study describes the results of two large-scale tests of dry granular flows interacting with a flexible barrier. Motions of multiple granular flows and their interaction behaviors with the flexible barrier are presented and analyzed. Impact forces on the flexible ring net directly and on the supporting structures have been measured and compared. The comparison result indicates the impact force reduced by the flexible ring net. Simple methods for impact force estimation are also verified.
