    Abstract: 民國85年賀伯颱風在阿里山地區連續24小時之降雨量高達1748.5公厘,同時在台北市之板和及社子地區造成嚴重水患,其中,板和地區之淹水面積達700平方公頃,平均淹水深度超過1公尺,淹水最深處甚至達3公尺。若賀伯颱風暴雨發生中心之降雨量直接下在台北都會區,其災情之嚴重恐不堪設想。
    Herb typhoon was up to 1748.5 millimeters in the 24hr duration rainfall in the area of Alishan in the 85th year of the Republic of China, cause the serious flood in Ban-Ciao, Yong-He and She-Zi sub area of society of Taipei at the same time , among them, flooding water area and is up to square 700 hectare of Ban-Ciao and Yong-He , it exceeds 1 meter flood water depth equally, it is most even up to 3 meters in the depths to flood water. If the storm of the center happens and put in the knowing area of Taipei directly in typhoon of Herb, it is too ghastly to contemplate that its disaster intimidates seriously.
    The study probe into at when extreme rainfall happenning incident research purpose department on city, estimate its flow of flood crest to defend and provide disaster relief the reference carried on the exercise of in follow-up ; While estimating the the depth of extreme rainfall , use separately: World Meteological Organization (WMO) statistic method, storm transposition and dew point adjustment method and average recurrence interval rainfall depth factor method, inquire into and act as river valley wutu the upper reaches of Keelung and collect in the water area separately, wutu station with flood-diversion stands in the Huo-Shao-Liao station before Yuan-Shan-Tzu flood-diversion, the depth when the extreme rainfall happens separately, step forward and mix the set of design hyetograph by extreme rainfall ,finally,mix geomorphologic instantaneous unit hydrograph afterwards, in order to estimate the flow of flood crest produced cause by extreme rainfall incident .
    Shown by the result of scenario simulations of study, when Herb typhoon takes place storm center use the storm transposition and dew point adjus method to transpose to Chu-Tzu-Wu from Alishan actually, it is 8250cms , and ''the worst case'' of this research to collect the flow of flood crest of water district in wutu of the upper reaches of Keelung river valley.
