Plenty of water, fine-rich sediments and a steep slope – that's all it takes to create a hazardous #debrisflow. #SLF researchers studied ten different debris-flow channels in #Switzerland to gain a fuller understanding of flows. More: www.slf.ch/en/news/reci...

To be prepared for the future, we need to understand the past and the present. That is why our researchers at WSL and @slfdavos.bsky.social collect data, build models and carry out observations. Read about how they do this and what they discover in the DIAGONAL magazine www.wsl.ch/en/publicati...

In CH, #forests account for 20-30% of total #snow storage in #winter. On south-facing slopes, snow usually lingers longer in alpine forests than in the neighbouring open terrain. On north-facing slopes, the opposite is true, as SLF researchers found. More: www.slf.ch/en/news/how-... 📷️ V. Haagmans

Avalanche winter of 1951: ⁠They are the cheapest and most important form of avalanche protection in terms of area – and they grow back naturally: forests. What the SLF researched after the avalanche winter of 1951: www.slf.ch/en/news/aval... ⁠ #SLF #SLFDavos #Snow #Avalanche #Winter #forest

After the #avalanche #winter of 1951, #SLF researchers developed a system for mapping areas at #risk from avalanches. The resulting colour scale for danger zones still forms the basis of the hazard maps produced today. Part 3 of the series on the avalanche winter of 1951: www.slf.ch/en/news/aval...

Ottimo recupero della neve ❄️❄️ a sud delle Alpi, oggi 14cm a Bosco Gurin (tot 56cm) e Campo Blenio (tot 25cm), 10cm a S. Bernadino (tot 54cm). Siamo fra il 60 e 90% dalla norma. Con le precipitazioni di settimana prossima pareggieremo i conti. 🤩 Mappa neve relativa @slfdavos.bsky.social

After the avalanche winter 1951, the #SLF stepped up its research into #avalanche protection. The findings led to a move away from walls, the usual defence mechanism until then, towards the #snow bridges and snow nets that remain common today. Part 2 of the #SLF series: www.slf.ch/en/news/aval...

How do avalanches affect pylons and other sensitive #infrastructure?
