Snowdrift formation on and around buildings can be serious problems in snowy cold region. The planning of buildings in such areas should consider the position of snowdrifts. A wind tunnel experiment using model snow is a useful tool for estimating snow accumulation on building. However, the law of similarity for this experiment has not been revealed. In this study, the authors have been investigated the effects of turbulence intensity on snowdrift. We carried out wind tunnel experiments using model snow particle under the different turbulence intensity of air flows. Snowdrifts on the leeward of the snow fence were compared under the several conditions.
