A time-dependent performance-based analysis was conducted to analyze the influences of sea-level rise and wave-height increase due to climate change on caisson sliding of the breakwaters designed in different water depths. We used the Goda’s spectral method to overcome the time-consuming problem in the calculation of the wave height at the breakwater site. In general, severe caisson sliding occurred when considering the climate change impacts. However, the influence of sea-level rise on the stability of caisson sliding is insignificant compared with that of wave-height increase. Especially, since the characteristics of caisson sliding are different depending on water depths, we have to establish countermeasure against these features for the design and maintenance of a caisson breakwater.
