| Outline of Final Research Achievements |
The field observations were conducted at Hasaki Coast, Japan to investigate the sediment cross-shore and vertical movements in the area of the swash zone to the offshore end of the surf zone. The analyzed results indicated that when the outer bar was formed the sediment movement in the onshore region and offshore region of the outer-bar moved without the correlation, however, the outer-bar formed by both regions of sediments. In contrast, when the offshore bar was not formed, fine sand located at the offshore side of the bar also contributes to the berm formation. Moreover, the mixing depths were observed from sand cores using fluorescent sand tracers. The spatial distribution of that could estimate by using the wave breaking height considering wave breaking zone. Furthermore, the beach profile change model for the foreshore zone was modified, and the results suggest that the model could be used for different coasts by using parameters related to the sediment diameter of the coasts.
