Abstract
PIV is an excelent method as a fluid velocimetory because it is a multi-point simultaneous measurament system. In this study, PIV is applied to shallow wave. In this paper, the shallow wave is also divided into small amplitude wave and finite amplitude one. The small amplitude wave, however, had been analysed theoretically, so we could make sure application of PIV for the shallow wave referrring the former theoretical work. After confirmation of the application, we then examine a finite amplitude wave. Because the shallow wave phenomena have nonlinear effect, it is considered to be interesting physically.
