Abstract

Extreme typhoon rainfall events can easily cause casualties and socio-economic impacts, thus thorough assessment of the potential losses beforehand will greatly enhance the disaster management conducted in Taiwan. This paper draws on the basin of Tsengwen Creek as an example and applies the unparalleled dynamical downscaling data as well as SOBEK inundation model along with Taiwan Typhoon Loss Assessment System (TLAS, by NCDR) to demonstrate the assessment system over the top ten occurrences in furfure 25 years (2075-2099). The results suggest an average loss of 13.6 billion dollars. And a further analysis aims at damage caused on lands of different-industrial, residential, and agricultural. The analysis shows an average loss of 52 billion on industrial lands, 22 billion on residential lands, and 21 billion on agricultural lands, which altogether, takes up 70% of all losses. A bating impacts resulted from the aforementioned land-use may decrease possible losses that the basin could undergo when are face with extreme inundation in future.
