Riverbed aggradation in front of the power plant outlet causes the decrease of power generation efficiency. Although bed excavation and embankment construction are conducted to keep riverbed elevation, sediment inflow occurs by embankment collapse caused by snowmelt runoff. In this study, hydraulic model experiments and 2-D numerical simulation were conducted in order to investigate embankment and river bed level variation. It was clarified that erodible embankments composed of bed material could concentrate flow on inner bank of river bend and restrain riverbed aggradation.
