Do watch this – probably the best ever debris flow video, from Austria last week
Posted by dr-dave
This remarkable video was recorded during heavy rainfall in the village of Virgen in Austria a little over a week ago:
The video catches the speed and power of these mudflows remarkably well. Note also the pulsing behaviour that they show, which is characteristic of these types of landslides, and also the very long wavelength standing waves that the flows created.

Dave,
At the 2 minute mark, it looks like the (empty??) channel has steps (or barriers) in the bottom, and the spacing of those “steps” looks similar to the wavelength of the standing waves. Do you think there is a connection?
