Abstract
Measures for tidal disasters are required as a adaption against climate change, though the methodology for above measures is still developing. Uncertainty of future climate change was one of technical hazards for their execution of adaption. In this study, at first, both of international and national adaption policy was reviewed. Then, tidal inundation simulation is carried out with consideration of future climate change. These results of simulation are used to discuss to reveal the recent hazards to develop disaster risk reduction method against climate change, such as risk-monitoring, estimation, evaluation and management (both prevention and mitigation).
