Located in an area where typhoons often pass, Osaka Area has long been subjected to frequent damage from surge disasters. If the emissions of the greenhouse gases, mainly carbon dioxide, stay at current levels in the future, global warming will be significant in the 21st century, causing rising sea levels, climate changes as well as the changes of typhoon in strength and scale. It is clear that rising sea levels and changes of typhoons could directly affect high tides. We therefore conducted numerical experiments with depth-integrated shallow water equations to examine the effects of these changes upon high tide in Osaka Bay.
