Slug-dye experiments were conducted to study the tidal exchange of the Seto Inland Sea with the largest hydraulic model in a horizontal scale 1/2000. To analyze the velocity at the margine of the dye cloud, image processing techniques have been developed. The techniques include the extraction of the boundary of the dye cloud and the flow direction through tuft images.
