Shallow landslides are induced by extreme hydrological events or by events of medium intensity but prolonged over time. Such slips involve generally limited portions of land; however, they are dangerous due to the absence of warning signals and the lack of knowledge regarding their possible evolution.
The aim of this paper is to study the evolution of shallow landslides affected by snowmelt and rainfall and to compare the observations done in situ by means of a statistical analysis of meteorological variables with those made in the laboratory.
Few authors have addressed the role of snow to slope instabilities, nevertheless, in the context of ongoing climate change, the study of glacier and snow melt must be further explored. For this reason, this work deals with the study of in situ seasonal processes observed at a mountain closed basin nearby Champoluc in Aosta Valley region. To understand and to improve triggering threshold in snowy region, snowmelt and meteorological analyses were carried out by means of a cutting-edge weather and snowpack station. All the available data have been examined with a series of statistical analysis to define snow melting trends in relation to meteorological conditions. After that, some tests were performed at GAP2 Lecco laboratory taking into account the onsite observations to evaluate the consequence of studied atmospheric conditions on a downscaled reproduced slope covered by snow. Therefore, it was possible to observe the direct interaction between soil and snow and how infiltration process takes place under settled conditions.
