耳川水系ダム通砂実施計画の策定に向けたダム通砂による魚類への影響予測

抄録

“Mimikawa River Basin Integrated Sediment Flow Management Plan” was compiled in 2011 by the Miyazaki Prefecture, as triggered by the huge sediment disaster due to the Typhoon Nabi, in 2005.

Kyushu Electric Power Company, which is responsible for dam installations, intend to carry out the sediment sluicing, incorporating Yamasubaru Dam, Saigou Dam, and Oouchibaru Dam.

It is assumed that in response to the change in the amount of flow of sediment due to sediment sluicing at dams, there will be changes in the river environment. We tried to expect the impact of sediment sluicing at dams on the fish for management plan of sediment sluicing at dams in the mimikawa river basin.
