Abstract: The paper is focused on the investigation of snow creep and settlement of alpine snowpacks. A detailed investigation of the constitutive behavior of snow for long-term creeping under low-strain rates is provided. The snowpack is considered as a compressible, viscous fluid. An assumption for a temperature and density-dependent viscosity and viscous Poisson ratio is provided in this paper, based on observations in nature and laboratory. The provided model is particularly applicable for settlement calculation of seasonal alpine snowpacks and computation of reaction forces on obstacles. The model is evaluated by numerous laboratory and field experiments. Different case studies are provided in this paper. Copyright Springer Science+Business Media B.V. 2011
