Videos of the Week #12 2021/22 | The science of snow and avalanches

Momentum = mass * speed

by Sebastian Müller 02/18/2022
You can describe snow and avalanches using physics. In order to understand a snowpack, thermodynamics is required above all, which describes the partial pressures and transformation processes of the crystals. The triggering of an avalanche requires a description of the mechanical properties of the snowpack and fluid dynamics are used for its propagation. However, science can sometimes be quite dry. That's why today we are presenting videos that make the subject matter more digestible.

Snowpack measurement

A very thorough introduction to the common measurements that are made in a snowpack.

Why does the snow melt so quickly in spring?

A very sad topic: melting snow.

Avalanche against buildings

Perry Bartelt talks about the impact pressure of avalanches on solid structures: cutting-edge research!

Modeling of a colossal dense snow avalanche

The RAMMS (Numerical Rapid Mass Movement Simulation) model applied in Val d'Aosta.

Snow avalanche simulations using the Material Point Method

The model that Disney's film Frozen has already worked with is extended here by a crucial component, the formation and propagation of fractures. Exciting!

The SLF Sionne avalanches

The classic among avalanches, here to enjoy in slow motion.

Ryggfonn Avalanche

Not only the SLF studies avalanches in the field, but also the Geotechnical Institute of Norway.
