Brief communication: Weak control of snow avalanche deposit volumes by avalanche path morphology
International audience Abstract. Snow avalanches are a major component of the mountain cryosphere, but little is known about the factors controlling the variability of their deposit volumes. This study investigates the influence of avalanche path morphology on ca. 1500 deposit volumes recorded betwe...
