Measurement of Fracture Mechanical Properties of Snow and Application to Dry Snow Slab Avalanche Release
Dry snow slab avalanche release is preceded by a shear failure in a weak layer or an interface of the snowpack, followed by a fracture in tension. At present, very little is known about the fracture mechanical processes. The aim is to improve our understanding of these processes in snow leading to dry snow slab avalanche release.
Measuring and modelling spatial variability of snowpack stability
Field measurements of the snowpack structure and stability with the aim to identify the causes spatial variability. Comparing modelled patterns obtained by the model ALPINE3D with field data in order to assess the model accuracy and to determine the causes of spatial variability. Relate modelled output to avalanche activity and predicted avalanche danger degree. |
