Abstract
This study deals expected sliding of breakwater within a period of service considering effects of climate change due to global warming. The influence of climatological change of sea level rise, storm surge and wave height on the breakwater stability is considered in detail. It is found that the impact of wave height change is the most significant than other components. The effects of climate change at the end of 21st century will increase the sliding distance with range of 0.2-1.8 m and it corresponds to 60-200% change in comparison with no-climate change condition. The influence of climate change for a period of break water service is necessary to be considered.
