This review article provides an overview of dry granular flows and particle fluid mixtures,
including experimental and numerical modeling at the laboratory scale, large scale …

Snow avalanches are the main natural hazard in snow covered mountainous areas
worldwide, frequently threatening lives and infrastructure. Avalanche research is inherently …

There is limited knowledge about groundwater storage in alpine catchments, although it
might strongly influence how these catchments react to earlier snowmelt due to climate …

The spatial distribution of alpine snow covers is characterised by large variability. Taking this
variability into account is important for many tasks including hydrology, glaciology, ecology …

The heterogeneous mountain snow cover is challenging the eye and the analytical mind of
the observer. The snow distribution affects water resources, natural hazards such as …

How terrain, snow cover properties, and release conditions combine to determine avalanche
speed and runout remains the central problem in avalanche science. Here we report on …

GEOphysical flow dynamics using pulsed Doppler radAR (GEODAR), a custom radar
system, images avalanches over the entire slope with high spatial and temporal resolution at …

Digital elevation models (DEMs), represent the three-dimensional terrain and are the basic
input for numerical snow avalanche dynamics simulations. DEMs can be acquired using …

The destructive power of an avalanche depends, among other things, on the overall mass
and the snow conditions in the avalanche path. So far, the knowledge on the effect of snow …

Powder snow avalanches (PSAs) are destructive flows as high as 200 m descending at
frontal speeds of up to 100 ms− 1. Dry snow PSAs typically develop a dilute frontal region …
