Abstract: Over the last 10 years, 2 French laboratories specialized on snow and avalanche research have joined their resources to investigate snowdrift effects and their consequences on the increasing of avalanche hazard. The experimental site is situated at 2 800 meters high in the French. Alps, at a place where the wind is canalized in 2 directions. The working method was based : • In a first time, on data measurements separated in automatic measurements (wind velocity, wind direction, snow depth, water equivalent of precipitation, ...) and in a set of field measurements (snow pits, taking of snow samples, vertical profile of snow density, stereo-photogrammetry, ...) • In a second time, on development of applications for the forecast of blowing snow events and the modeling of snow distribution. • The current project aims at testing an integrated chain of models which can determine the snow distribution by taking into account the local topography. This poster will present the results of a climatological study made by using the series of data and the results of the modeling.
