“…The knowledge about the various physical processes of snow avalanches extracted from field data over the decades is carefully discussed by Issler et al (2020). Reports on field observations, such as Issler (2020) and Furdada et al (2020), provide consistent conclusions about the destructive force of snow avalanches and offer valuable estimates for mass, speed, and run-out distances. For instance, data from several real avalanches helped Sovilla, Burlando and to model the complex impact of entrainment processes on run-out distances, and Gauer (2014) to validate models dealing with front velocity.…”
