On the Study of Snow Distribution on the Face of Slope by Means of Terrestrial Photogrammetry

Abstract

Several authors have made the observations on the phenomena of the snow avalanches, the snow creeps, the snow glides in the heavy snowfall regions, North Japan. However, these were investigations without the snowfall of the face of slope.
In this paper the authors propose to utilize the terrestrial photogrammetric method in order to make clear the distributional tendency of the snowfall on the face of slope which was the first time to take advantage of such a method in Japan.
The authors emphasize that this method is useful for measuring the distribution of the snowfall on the face of slope.
According to the authors' observation, the berm seems to play an important role in the prevention of gliding snow.
