Outline of Final Research Achievements

Projection of typhoons, storm surges and waves were conducted for impact assessment of coastal environment in the future.
The observed sea level rise was analyzed based on the satellite observation and is 3 mm/year around Japan. Future changes of tropical cyclone activity was analyzed based on CMIP3 and CMIP5 results. The cyclogenesis number will be decreased and the tracks will be shifted to Eastward at the Northwest Pacific Ocean in the future. Risk of storm surge is estimated targeting Ise-wan (Vera) typhoon. The maximum level of storm surge and related uncertainty is discussed. The impact of coastal morphology was examined and shore line change based on standard sea level rise analysis is not sufficient for dynamic behavior of beach morphology.
