極端氣候的降雨我們越來越不可預測(1500豪米雨量)
The rainfall of extreme weather is more and more unpredictable.
讓我們想像一個不是不可能發生的場景
Imagine a scene which is not impossible.
莫拉克阿里山的雨量
如果僅一半多下到北部首都附近的石門水庫
會發生什麼狀況
What if half of the rainfall in Ali Mountain when Morakot came falls in to Shihmen Reservoir which is near the capital?
依照台大 水工所 教授李鴻源估算
雨量若超過1500豪米
已大到超出石門水庫排洪的速度與限度
整個水壩甚至可能垮掉
Calculated by ph. Lee, HY. R. I., N.T.U., the reservoir might even failure if the rainfall go beyond the range that it can load.
潰壩
Dam Failure
