| Research Abstract |
In this research, correlations between shoreline change rates and six frequency-sectioned wave energy fluxes were discussed using a 5-year data set of beach profiles and offshore waves observed at the Hasaki coast. Also, an effect of foreshore beach shape on shoreline backward movement speed was discussed. From the results, it is possible to separate shoreline erosion events from shoreline advance events and shoreline stand still events by using frequency-sectioned wave energy fluxes. Furthermore, the results revealed that the shoreline position and foreshore shape affect shoreline backward movement speed. This indicates that for the estimation of the shoreline change rate, we need to consider not only wave energy but also shoreline position and foreshore shape.
