 note = {In this study, we examined some aspects of the drift motion of ice floes driven by bore-like tsunamis
through a series of laboratory experiments. This work investigates the disintegration of a tsunami into a
train of undular bores, with floating ice models on the surface. We recorded the experiments by digital
cameras, and the position of an ice floe as a function of time was determined by digitalized pictures using
image analysis techniques, namely, PTV. Several interesting details are revealed by these experiments. It
was observed that run-up heights of wave front increase by over 70%, and time-series waveforms of undular
bores agree well with those of velocities of model tracers. This means that bore front can accelerate the
movement of ice floes violently. This work highlights the potential risks of ice floes, which can be hazardous
to river structures, such as bridge piers, floodgates and intake screens.},
