Flow slides and rock slide–debris avalanches
Posted in Thesis on 10/27/2008 06:52 pm by MikaFrom Geohazards IV paper:
The frictional rheology can be used for dry friction in the source area, with a transition to the Voellmy model where significant entrainment of saturated soil begins. A similar scheme was used for the coal waste flow slides. A switch from frictional to Voellmy models is often required to produce satisfactory simulation when events initiate on open slopes and then become channelized (Ayotte and Hungr 2000, Hungr and Evans 2004).
