AB - This study is to analyze the characteristics of impact force by debris flow based on the Finite Difference Method (FDM), according to the variance of supplying water discharge and channel slope angle. The more supplying water discharges, the earlier fluctuation of debris flow is occurred with a longer duration and a higher amplitude of impact force. The debris flow velocity is speedier at the fluctuation points than on the downstream channel and maintains for a few seconds. The impact force of debris flow at the fluctuation points is stronger than at the early occurrence points. This finding indicates that the supplying water discharge, which is the energy source for debris flow, interacts with the particles of the flowing debris flow and thus the energy of debris flow increases. Such rising impact force of debris flow contains great energy and keeps attacking the check dam.
