抄録

Typhoon 7 hit Honshu on September 22, 1998. This storm brought about a certain amount of local damage in the path of the typhoon. Trees in the southern part of Nara Prefecture were blown down. Field survey and analysis of aerial photographs taken after the storm were carried out to determine some of the characeteristics of the trees blown down. Along narrow gorges the blown down trees on the steep slopes lay scattered in the direction of the downward grade. The blown down trees on slopes in the open areas lay in the same direction as the blast of the wind.The most trees blown down entirely from their roots and a few trees were broken at the middle of their trunks. The structure that check the outflow of the downed trees and the incidental landslides or debris flow sediment was proposed to be built from the logs of rather large diameters available at the sites.
