ABSTRACT

Recently, human and property damages have been frequently reported by debris disaster such as debris flow and landslide, which were caused by a variety of factors such as intensive rain due to climate change and thoughtless development of mountainous areas. In order to reduce the damage by such debris flow, it is required to quantitatively estimate the impact pressure of the debris flow and to evaluate the structures in the hazardous areas and the surrounding facilities. In this paper, we developed an impact pressure model Type 1 reflecting the debris flow characteristics and an impact pressure model Type 2 reflecting the topographic characteristics of the mountain watershed. The reliability of the Type-1 and Type-2 impact pressure models was verified based on the impact pressure of the commercial model RAMMS.
