—This study is aimed at using the physiographic
inundation model to simulate inundation potential of 24-hour
and 48-hour design rainfalls for baseline and climate change
scenarios for several return periods and then discuss the impact
of climate change on inundation potential. The Typhoon
Haitang in 2005 and Typhoon Morakot in 2009 were used to
verify the physiographic inundation model by comparing with
field investigations. Furthermore, the inundated potential was
simulated with the hydrologic conditions for the duration of
24-hour and 48-hour design rainfalls for baseline and climate
change scenarios for 25- year, 50- year, 100-year and 200-year
return periods. The comparisons reveal that the inundated
areas and volumes increase significantly under climate change
scenario. Hence, climate change results in more serious flood
