Published in Nature Communications, a new study by the Swiss is shedding light on how, why, when, and where “snow-slab” avalanches occur.
Using high-tech 3d modeling combined with elements of continuum mechanics, the group of researchers created extremely accurate representations and models that give new insight into avalanche triggers, slope angles, and release points.
“On the basis of a new elastoplasticity model for porous cohesive materials and a large strain hybrid Eulerian–Lagrangian numerical method, we accurately reproduced the onset and propagation dynamics of anticracks observed in snow fracture experiments.”
The new models could play an integral role for avalanche forecasters in the future. Just imagine, with the following tech avalanche centers could potentially tell backcountry travelers exactly where a slide is likely to occur.
