Observations were tried to measure the amount of snow deposition and the aspect of snow-melting. 29 snow depth meters set up around obstacles such as gatepost, windbreak, meteorological experimental field, and in the forest in Nopporo Experimental Forest.The results are as follows : The deep snow-hollow was formed on the leeward side of the gatepost, and the range of the hollow reached to three-four times as long as the gate height.The gentle slope was formed in front of the windbreak of thick branches, and the snow deposited to the leeward side of it. The range of snow deposition was twice length of the tree height. But at the back of the windbreak of thin density, the snow deposition was not obvious appearrance. The snow stripe was formed around the stockage of the meteorological experimental field.The snow deposition in the forest was shallower than that of the open to the extent of 20-30 per cent.The snow-melting around the windbreak or stockage, were delayed more than 3 days, in the forest were delayed about 10-15 days as compard with that of the open.It seems that the retardation of snow-melting depend on the species of the tree and the crown density of the forest stand.
