摘要

Heavy rain hit the Yabe River basin in Yame City, Japan on July 14, 2012. This heavy rain caused landslides and debris flows along the upstream river reach in the mountain areas. These resulted in a flood with a significant amount of sediment and wood. The structures in rivers, such as bridges with a pier, caused accumulation (a jam) of woody debris and then overflowed the banks at several river sections. It is important to know the characteristics of the formation of a woody debris jam from the viewpoint of flood defense. The purpose of the present paper is to investigate the relationship between a log jam and a structure in a river. In the present study, logs are assumed representative of woody debris in rivers.
