抄録: | At the downstream of the dam, we are working on improvement of flow and sediment dynamics such as flush discharge and sediment reduction.However, flush discharge has not been done from the viewpoint of whether it is the scale that contributes to the increase of the riverbed disturbance accompanying the movement of riverbed material. In addition, the size and amount of the sediment loading to the increase in the degree of riverbed disturbance are unknown. In this study, we examined indices to evaluate the degree of riverbed disturbance and proposed a method of setting goals for countermeasures to improve flow and sediment dynamics. As a result, the riverbed disturbance level was divided into two stages with the planned high water discharge of the dam as the boundary, and the coarse grainization indices and the riverbed disturbance indices were shown. |
