The flood management in dam reservoirs has been performed by using a water level observed near the dam body. However, the characteristics of the flood propagation of water level and discharge hydrograph are different in each flood flow, especially inflow of large scale flood flows. For efficient and safe dam reservoir management, it is important to clarify the mechanism of flood propagation. In this study, the hydraulic model test was carried out in order to investigate the characteristics of reservoir storage and flow mechanism in dam reservoirs. Moreover, the flood flow analysis method was developed to understand characteristics of flood flow dynamics in dam reservoirs and applied to hydraulic model tests of dam reservoirs.
