  Abstract: In the framework of the "Risk, Research and Innovation" project carried out by the Mountain Risk Research Team, the glide-snow avalanches are studied. As the wet-snow avalanches, the glidesnow avalanches are highly dangerous because of the large possible involved volume of snow and the difficulty of forecasting their release. Before the '60s, these phenomena have only partially attracted the scientific interest but afterwards the knowledge on formation and processes related to wet-snow and glide-snow avalanches has grown significantly. Particularly, the role of free water at the snow/soil interface has been analyzed as key factor responsible of the gliding rate and the acceleration of the gliding snowpack. The experimental approach on the analysis of formation of glide-snow avalanches is based on the set-up of four test sites within the Monterosa Ski resort in Aosta Valley (NW Italian Alps) during summer 2013. The snow gliding of the snowpack, which can possibly results first into the formation of glide cracks and then to avalanche releases is monitored in two test sites. Glide shoes, temperature and water content sensors are installed at the snow/soil interface to monitor the processes. A third test site is devoted to the test of innovative sensors for snow humidity and density measures. The last test site is dedicated to the evaluation of the effectiveness of different protection measures with respect to the risk related to wet-snow avalanches. The paper describes the test sites, the objectives of the research and shows some preliminary data.
