説明

When a debris flow containing woody debris reached the Nakatani-gawa open-type steel-pipe gridded sabo dam in the Nakatani River, a lot of sediment and woody debris were trapped by the dam. The sediment deposited at the dam was later excavated to observe its vertical structure. It was concluded from the observation that : 1) the sediment transport was caused by a typical debris flow containing woody debris, and very large, mile-sized, and small rocks, and that : 2) not only the sediment in the frontal part of debris flow, but also the successive trains of debris flow was trapped by the woody debris that occluded the opening sections of the dam.
