Abstract
Climate change impact due to global warming on beach profile is projected based on the global climate projections. Changes in the coastal external force due to climate change are not only sea level rise, but changes in the wave characteristics such as wave height, period, and wave direction are also considered to beach profile changes. Kaike coast in Japan is surrounded by Shimane Peninsula. By the distinctive terrain facing the Miho Bay, changes of wave characteristics at the Sea of Japan is considered to check the sensitivity on the beach terrain. In this study, the bathymetry changes of Kaike coast protected by existing artificial reefs and sand recycling are simulated forced by future climate conditions and it is revealed that wave climate gives significant impact on the bathymetry.
