Abstract
The run-up of an incident bore onto a dry bed was investigated by the flow visualization of hydrogen bubbles. The time control of the equipments in millisecond enabled the precise quantitative measurements of the velocity profile at the shoreline. It is shown that the development of the boundary layer is close to that of the Rayleigh problem. The numerical analyses of the characteristics installing this result give good estimate of the run-up phenomena. The local term and the convective term of the momentum equation are shown to be dominant near the front.
