Supplementary data for "Detrainment and braking of snow avalanches interacting with forests"

We are releasing the data as the supplementary information for our manuscript “Detrainment and braking of snow avalanches interacting with forests”.

Figure 5. Data of Fig. 5. Evolution of the detrainment mass per unit of area of snow with the velocity (regular staggered forest, e= 8m).

Figure 6. Data of Fig. 6. Evolution of the detrainment mass observed for the one tree arrangement and the fits with the tree diameter for 2 flow regimes: Case 1 and Case 2 with respectively a front velocity of12.5 m/s and 10.6 m/s, ‘maximum’ refer to the maximum mass stored behind the tree and ‘final’ refer to the final mass stored. A slope of 30◦, and a top wedge angle of 60° (from measurements Feistl et al. (2014)) is used for the theoretical model (Eq. 8)

Figure 8. Data of Fig. 8. Evolution of the detrainment mass per unit of area with the tree diameter for different types of snow and front velocity (regular staggered forest, e = 8 m)

Figure 9. Data of Fig. 9. Evolution of the detrainment mass per unit of area with the forest density for different front velocities (regular staggered forest, snow properties: case 2, d = 1 m)

Figure 10. Data of Fig. 10. Evolution of the detrainment mass predicted with the model (Eq. 11) and with the observation, r²=0.9926

Figure 11. Data of Fig. 11. Temporal evolution of the kinetic and potential energy without forest and with a regular staggered forest (Case 2, v₀ = 6 m/s)

Figure 12. Data of Fig. 12. Temporal evolution of the detrainment energy and dissipation due to the forest (Case 2, v₀ = 6 m/s)

Figure 13. Data of Fig. 13. Energy detrainment and dissipation for different snow properties (1: case 1, 2: case 2, 3: case 3 with M=1) and for 3 types of forest structure (regular aligned, regular staggered and random)
