RESEARCH ON WAVE HEIGHT AROUND A DETACHED BREAKWATER AND THE AMOUNT OF SHORELINE CHANGE AND THE AMOUNT OF SHORELINE CHANGE
A detached breakwater is used in order to protect a shoreline. After constriction, a tombolo is formed back and the deposition effect in back is checked. There is no settled method in prediction of the shoreline position after detached-breakwater installation. Since the shoreline data after installation is scarce, it is difficult to evaluate the deposition effect quantitatively. This research considered the wave quantity change around a detached breakwater, and correlation of the amount of shoreline change. It tried to predict a shoreline position from the change in the wave height ratio around a detached breakwater. As a result, the amount of shoreline change becomes in alignment with change of a wave height ratio. Although a change of wave heightratio is small, amount of shoreline change increases. This showed that shoreline distance of detached-breakwater back could not be determined only by change of wave quantity.
