The well known Voellmy runout equation is routinely used to dimension protective barriers for snow avalanches. This paper shows that the Takahashi and Yoshida runout equation for debris flows can be easily adapted to snow avalanches within the context of the Voellmy model. The adaptation is especially unambiguous when applied to the calculation of run-up; i.e. runout on a steep adverse slope. A numerical comparison indicates that the Voellmy equation underestimates run-up by at least 50% compared to the proposed method.L'\ue9quation de distance d'avanc\ue9e d'apr\ue8s Voellmy est souvent utilis\ue9 pour dimensionner la hauteur des barrages protectifs contre les avalanches.
