Abstract
Shallow water wave hindcastings are conducted in Osaka Bay and Kii Channel for not only the 3 large typhoons in the early 1960s, which caused an enormous amount of damage to Osaka Bay areas, but also the most recent 5 strong typhoons with the sea wind distribution properly evaluated using land-based wind measurement. A good agreement between abundantly-acquired wave measurements and the corresponding hindcasts for the recent typhoons may guarantee to some extent a reasonable accuracy of the wave hindcasts for the 3 typhoons in the 1960s which are performed with the sea wind distribution evaluated by the same method. It is deduced that wave heights generated by the 3 typhoons may change greatly 50-year return wave heights in Osaka Bay estimated using the wave hindcasts for intense storms in the recent 30 years.
