Abstract

This study proposes an optimum design method of caisson type breakwater covered with concrete blocks considering the effects of climate change on coastal environment, such as changes in the sea level, storm surge and wave height. Life cycle cost (LCC) of armoured breakwater in the future condition becomes smaller if heavier blocks than necessity weight estimated by an empirical formula are employed for the case that its design wave height is smaller than 8 m in the present study conditions. In LCC evaluation, economic indicators, such as the social discount and GDP, are considered. Although LCC and optimum specifications of breakwaters will change due to the external forces, the proposed design method is generally applicable by employing the latest reliable future climate projections
