Effect of Climate Change on Performance-Based Design of Caisson Breakwaters

摘要: This paper presents a method to incorporate the effect of climate change on performance-based design caisson breakwater and its application East Breakwater Port Hitachinaka in Honshu, Japan. The up-to-date projection estimated future sea-level rise 0.25-0.6 m wave-height increase 1.7 (from 8.3 10 m) during 21st century this area. influence sliding was minimal; much smaller than water depth at site. When effects were not included, calculated same width as that constructed breakwater, partly validating consistency between conventional deterministic methods methods. dictate an approximately 1.5 0.5 for linear parabolic increases wave height, respectively, which are 6.8 2.3% present 22 m. Finally, it is recommended be designed using projected height level 30 years from construction, if used taken into account.
