Title: Dye Diffusion Experiment in a Longshore Current Field
Abstract: AbstractAn instantaneous dye-release experiment was conducted in a coastal field study. Dye was released into a longshore current field from the research pier HORS located in Hasaki, Japan. The release point of the dye was placed in a wave reforming zone which lay between a bar, where limited breaking occurred, and shorewards final surf zone, where all waves broke. Longshore current was present between the bar and shoreline. Deformation of the dye patch was observed efficiently and effectively with a moored video system. Some essential characteristics of the surf zone hydrodynamics and shear flow dispersion are explained from the results of video image analyses of the temporal variation of the dye patch distribution.Keywords: Dye-releaselongshore currentsurf zonediffusiondispersionfield observationvideo imaging
