Abstract

When a solitary wave is running up to a slope (15°) obliquely at an angle of 30° to a shore line we can record the side view of this runup phenomenon on videotape by illuminating the water surface with a laser light sheet. The water has been mixed with the fluorescence. A solitary wave transforms while propagating to the slope. We get the wave profile by image processing the recorded images. Between these wave profile images we can calculate the cross correlation and decide the beginning point of transformation and know how the wave transforms and loses the symmetry.
