Abstract
The purpose of this study is to analyze the sediment transport of Miyazaki Coast, especially the dominant longshore direction of sand transport, from the results of recent 3 years sand tracer experiment and of the analysis of currents observed by camera systems during the experiment. The dominant direction obtained by accumulation of longshore sediment transport rate estimated by equation of Kraus et al.(1982), which is based on the breaking wave height and nearshore currents, agrees with the direction of motion of the tracer. In addition, it becomes clear that there is a high correlation between the distance of tracer movement and the longshore sediment transport rate. It is also obvious that sediment transport to south is predominant in the experiment period.
