| Research Abstract |
A medical X-ray CT scanner was applied to dynamic measurements of beach profile changes,sedimentary structures, and sediment transport processes during wave actions in thelaboratory experiments. In order to measure the cross-shore evolutions both of beachprofiles and sediment transport process, the CT-scanner moves automatically along theflume. By reconstructing three-dimensional images using Hounsfield units, the evolutionof beach morphology was examined. Because medical X-ray computed tomography has theadvantage of a data acquisition time of 1.0 seconds for sediment transport processesduring wave action, the obtained data, such as that of the suspended and bed load, areuseful for clarifying the mechanism of profile change and validating numerical models.
