Climate change is expected to lead to increases in both sea level and typhoon intensity, which could threaten the stability of break waters in the future. In this study, calculations using the SWAN model showed that a 10% potential increase in the future wind speed of typhoons resulting from the warming of surface sea temperatures can lead to a 21% increase in the significant wave heights generated by these winds. To understand the effect that this would have on break water stability, the expected sliding distances for the break waters at Shibushi Ports in Japan were estimated using a probabilistic design method. The results show that in the future the expected sliding distances may be come five times greater than at present, due to a combination of increases in sea level and wave height.
