Abstract: The snowdrift problem is particularly important individuals involved in the study of the dimensions avalanches defensive structures. In fact, it has been noted that the structures that have been realized have the tendency to facilitate the snow accumulation with the inconvenience of becoming less effective. Therefore, it arises the problem of planning complementary structures to the actual active defensive structures such that they regulate the accumulation a..'1d avoid the filling of bridges and snowpacks already established as a defense of sensible areas of the territory. It 15 then evident that the right dimension and a correct positioning on the ground are fundamental principles in order to accomplish the established purpose, and also it appears evident that an erroneous positioning on the ground can introduce deleterious effects which might even worsen the initial situation that preceded the intervention itself. The planners, often find themselves in the need to make up projects without the technical knowledge to the problem of where to allocate the structures. Therefore, in order to contribute to the solution of this problem, the II Ufficio Neve e Valanghe of PAT II projected and accomplished an experimental field for the study of deflecting panels (snow barriers).
