Abstract—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 damages.
