ABSTRACT
Climate change is making extreme weather events more frequent. Paradoxically, longer dry seasons and more severe floods are issues that global disaster management must address. The rising number of “unprecedented floods” indicates that traditional frequency analysis is limited in assessing the potential hazards of extremely large floods. Recent studies suggest that very large floods are more likely to occur in specific types of catchments. Analyzing these catchments through their daily hydrological dynamics may be more effective in predicting the occurrence of “unprecedented floods.” Such an approach offers a more promising solution for effective adaptation strategy in flood hazard management.

氣候變遷使得天氣極端事件變得越來越頻繁。儘管非常弔詭，旱季更長、洪災更甚已是全球災害管理必須面對的問題。越來越多的「前所未有的洪水」，顯示出傳統的頻率分析在評估超大洪水的潛在危害上能力有限。最近的研究指出，超大洪水容易發生在一些特定型態的集水區。藉由集水區的日常水文動態來分析這類的集水區，可能可以更有效的預示「前所未有洪水」的發生。這種方法為洪水災害管理中的有效適應策略提供了更有前景的解決方案。
