We performed a simulation of sediment and $$^{137}$$Cs behavior in the Ogaki Dam Reservoir during a heavy rainfall event occurred in 2013. One-dimensional river and reservoir simulation scheme TODAM was applied for calculating the time dependent migration of sediment and $$^{137}$$Cs in dissolved and sediment-sorbed forms in the reservoir. Continuous observational data achieved in upper rivers were used as the input boundary conditions for the simulation. The simulation results were compared with the continuous data achieved in the lower river and we confirmed the predicted values of sediment and $$^{137}$$Cs in sediment-sorbed form at the exit of reservoir satisfactorily reproduced the observational data. The simulation result of a heavy rainfall event shows that the reservoir plays an important role to delay and buffer the contamination movement in heavy rainfall events.
