摘要

Physical and dynamic characteristics below bed surface can be an important parameter to discuss the physical environment characteristics of habitats for aquatic fauna and flora. However, most of previous researches on sediment in rivers treat the sediment characteristics on the bed surface only and the knowledge of physical and dynamic characteristics below bed suriace is not enough to discuss the physical environment characteristics of habitat for aquatic fauna and flora. In this research, the spatial distribution of the bed strength, the porosity of the bed and the sediment size distribution of bed material are studied on the bar located in the Kizu River in Kyoto, Japan by use of the field survey and the numerical analysis (Takebayashi et al (2007),Sulaiman et al (2007)). Furthermore, relationship among the spatial distribution of the bed strength, the porosity of the bed and the sediment size distribution of bed material is discussed.
