Short summary
Snow avalanche motion is strongly dependent on the temperature and water content of the snow cover. In this paper we use a snow cover model, driven by measured meteorological data, to set the initial and boundary conditions for wet-snow avalanche calculations. The snow cover model provides estimates of snow depth, density, temperature and liquid water content. These initial conditions are used to drive an avalanche dynamics model. The runout results are compared using a contigency analysis.
