This new paper, which is a collaboration with colleagues in France, provides some information on Bayesian approaches to assessing avalanche risk.

Putting the video together for the web site

We had fun yesterday trying to film the video for the Royal Society on-line exhibit in Cambridge. Finding somewhere quiet proced to be pretty difficult. Luckily Josh Caplan (Trinity College) was doing an experiment at the time that we were able to film too.

A few years ago, Martin Kern (at SLF in Switzerland at the time) and I worked on the script for this BBC programme on avalanches.

Other research

I also work on turbulent flows. Our group’s homepage is at: sheffieldfluidmechanics.co.uk

Here is a photo showing the steepness of the avalanche path in Switzerland that we use for experimental testing.
