Rock avalanche mobility: The role of path material - ResearchGate
WebDec 7, 2024 · The major aim of this experiment is to investigate whether fragmentation is the dominant mechanism of hypermobility of rock avalanches, by determining whether fragmentation occurs throughout the emplacement process. The results of the grain-size distribution and fractal dimension in this study have provided important insights regarding … WebDec 11, 2024 · Rock avalanches, as one of the most threatening geological disasters in mountainous regions, have drawn much scientific interest because of their sudden occurrence, huge volumes (> 10 6 m 3 ), high velocities (> 20 m/s), and extremely low Fahrböschung (typically 0.1 to 0.3) (Heim 1932; Corominas 1996; Korup et al. 2007; Xu et … pubs in newcastle under lyme
