Supplementary videos for "Transient wave activity in snow avalanches is controlled by entrainment and topography"

<p>Movie 1. Field avalanche happened at the Vall&eacute;e de la Sionne test site on 3 February 2015.</p> <p>Movie 2. Numerical simulation of the 2015 VdlS avalanche. The color in the video shows the flow velocity, and the colorbar can be found in Fig. 3 of the manuscript.</p> <p>Movie 3. Roll-waves in the simulated avalanche, where the particles ahead of the wave are eroded and the particles at the wave tail are not deposited. The color in the video shows the flow velocity, and the colorbar can be found in Fig. 3 of the manuscript.</p> <p>Movie 4. Erosion-deposition waves in the simulated avalanche, where the particles ahead of the wave are eroded and the particles at the wave tail are deposited. The color in the video shows the flow velocity, and the colorbar can be found in Fig. 3 of the manuscript.</p>
