Eighteen (18) retrogressive thaw slumps (typical landslides in ice-rich permafrost) in northern Canada were monitored for 3 years to investigate the characteristics of their retrogressive behaviour. The head scarp retreat distances and scarp wall heights were measured annually. The first year monitoring results from 13 of the sites were released earlier, which demonstrated a correlation between thaw...
Thirteen landslides (retrogressive thaw flows) were investigated to study the behavior of thaw retrogression in permafrost in the Mackenzie Valley, Northwest Territories (NWT), Canada. Those landslides are all in fine-grained ice-rich permafrost soils. Such landslides usually start from small-scale slope failures followed by retrogressive thaw flows when ice-rich permafrost soils are exposed to the...
