| Research Abstract |
An obliquely descending eddy caused by wave breaking is a strong three-dimensional phenomenon. However, there have been a limited number of studies using hydraulic model tests that examined the distribution of obliquely descending eddies along coasts and the distribution of the three components of velocity. In the present research, the structure for the formation of obliquely descending eddies was examined. As a result of the study, it was found that obliquely descending eddies formed along coasts can be categorized into different types : "A structure wherein two vortexes come into close proximity," and "a structure wherein the distance between the two vortexes remains constant."
