Abstract
n order to represent the forest cover effect on the snow-melt quantitatively and to make it a basis of snow-melt estimation for the whole basin, two experiments were tried in the forest in Okutone region (the headwaters of the Tone River), one to determine the beech-forest cover density by balloon measurements from the sky and the other to compare the amounts of snow-melt and several meteorological factors between inside and outside the forest. The result suggests that our theoretical estimation of the amount of snowmelt in the forest is successful.
