Tsunami propagation into rivers is one of the important real phenomena. During this process, the tsunami celerity and the flow velocity are significant physical parameters to understand tsunami behaviors. However, the availability of measurement data was not sufficient in case of the 2011 off the Pacific Coast of Tohoku Tsunami. Nevertheless, several video data can be used to assess the physical parameters such as tsunami celerity and flow velocity. In this study, as a video image analysis method, Particle Image Velocimetry(PIV) and Particle Tracking Velocimetry(PTV) were used to estimate the tsunami flow velocity. Furthermore, the analysis result of the video image data was verified by using the conservation equation. The tsunami physical parameter from PIV shows good comparison with other approaches.
