内容記述 | This research detailed the interaction between the dispersive wave train and ice floe in tsunami-induced wave propagation upstream in rivers. First we conducted hydraulic experiments to investigate the effects of ice floe length and thickness using field observation data obtained when river ice breakup and scattering were caused by the 2011 Tohoku Pacific-Coast Earthquake tsunami. We measured transportation velocities of ice floes using an image analysis technique. Second, particle based numerical simulation was conducted, by which we can easily handle with violent free surface motion and ice floe movements. Direct comparisons of experimental photos and their corresponding simulation snapshots are made in terms of the reproduced waveforms and the ice floe displacement. The work highlights potential risks of ice floes when tsunami propagation upstream in a river occurs. |
