Prevention and Mitigation Against Debris Flow and Woody Debris in Japanese Design Using a Steel Pipe Open Sabo Dam
Natural hazards and disasters, such as debris flow or woody debris, have occurred in the last few years because of the heavy, record‐level rainfall attributed to climate change and the increase in typhoon strength in Japan. Therefore, to protect human lives and property, a steel pipe open Sabo dams were installed on alluvial fans. Dams have opening interval and can trap debris flow, including boulders and driftwood, at the time of occurrence, and naturally lets sediment or small stones flow down. The feature of such Sabo dams set at an optimum interval allows them to trap boulders and driftwood. Moreover, the steel frame maintains their structure against external forces such as the fluid force of debris flow and against the collision with boulders. This study introduces application examples of the steel pipe open Sabo dams and discusses the contemporary design and planning manual in Japan.
