説明
We investigated effect of a fixed weir on sediment transport characteristics and aquatic invertebrate. The weir is located in an upper reach of Katsuura River (Tokushima Pref., Japan). We measured hydrologic parameters and performed quantitative samplings for benthic animals. In the rapids, component ratio of the sediment inside river bed changes in the downstream of the weir due to only the sand passing through the weir. Therefore, the species richness decreases because the habitats of benthic animals are influenced by this change. Especially, the animal having a life type of creeping is suggested to be strongly affected. However, in a mountain stream, effect of damming on eco-system in the downstream is suggested to be reduced in contrast to that in middle and lower reaches.
