| Summary: | 碩士 === 國立交通大學 === 土木工程學系 === 85 === Taiwan was infested with typhoons for 3.75 times per year by averaging the typ
hoon data of Central Weather Bureau (CWB) from 1897 to 1992. Mosttyphoons land
ed on or passedby the eastern taiwan. The induced large waves by typhoons shou
ld do a severe impact on the coastal construction in the eastern Taiwan. It is
important to establish a typhoon wave calculationmodel to estimate the typhoo
n waves for the east coast of Taiwan. After relating typhoon waves to typhoon
strength and distance between insterested point and typhoon, we proposed an i
mperial formula for wave height and period in terms of information posted by
CWB. Furthermore, the wave height of a return period will be available by usi
ngthe extreme statistics proposed by Goda (1989). We chose Hualien harbor as a
n example and found its wave height of different return period. The wave heigh
t of 50-year return period is 10.2-12.8m with a deviation of 0.8-1.6mfor Huali
en harbor. The wave calculation model was programmed in the Visual Basic Lang
uage to facilitate to predict waves for convenient and obvious practice. A su
ggestion that we should collect more typhoon waves and know more information o
f Typhoon is given to future promotion for wave calculation model.
