Outline of Final Research Achievements

In this study, the effects of damming on the downstream ecosystems in the Mimi River, Miyazaki Prefecture, were investigated. We conducted the sediment dynamics monitoring using UAV and the monitoring of biomass changes in ayu (Plecoglossus altivelis altivelis) and Stenopsyche marmorata using environmental DNA (eDNA) in the downstream section of the dam and clarified the effect of the riverbed variation on the biomass changes. The newly developed river ecosystem model enables us to quantitatively evaluate the impact of riverbed variation on riverine ecosystems. By integrating monitoring methods such as UAVs and eDNA into the developed river ecosystem model, we can examine the sustainable integrated sediment management method for both flood control and the environment.

Academic Significance and Societal Importance of the Research Achievements

本研究では耳川を対象に河床形状や生態系の応答に関する実証実験を行い,流砂系の変化に対する河床形状や生態系の応答を明らかにした.また,土砂動態と河川の水質・生態系の連成モデルを開発した.このモデルは生物量を定量的に評価できる点において,学術的に新規性が高い.さらに,UAVや環境DNAによるモニタリング手法と開発した河川生態系モデルにより,治水と環境を両立する持続可能な総合土砂管理法を検討することが可能であることを明らかにしており,今後の河川管理に大きく貢献すると考えられる.
