Abstract The past geomorphic activity of flash floods in the Eastern Mediterranean has been poorly understood. Despite the general increase in mean annual temperature and decrease in annual precipitation totals, intense rainfall during strong cyclogenesis is still expected under a changing climate. The aim of this study was to identify past flash flood events on the island of Crete (Greece) to (i) create a regional chronology of flash floods using dendrogeomorphic dating and (ii) describe climate triggers responsible for the most distinct events. The sampling of 398 trees and shrubs from eight catchments enabled the reconstruction of 76 flash flood events over 43 different years. The length of the chronologies ranged from 27 to 125 years, and the most distinct events were recorded in the 1993–94, 2000–01, and 2006–07. Significant differences (p

东地中海的山洪重建:克里特岛基于区域树木年轮的年表和气候触发评估

摘要 过去对东地中海山洪暴发的地貌活动知之甚少。尽管年平均气温普遍上升,年降水总量减少,但在气候变化的情况下,强气旋期间仍会出现强降雨。本研究的目的是确定克里特岛(希腊)过去的山洪暴发事件,以 (i) 使用树状地貌测年创建山洪暴发的区域年表,并 (ii) 描述导致最不同事件的气候触发因素。对 8 个流域的 398 棵树木和灌木进行采样,重建了 43 个不同年份的 76 次山洪事件。年表的长度从 27 年到 125 年不等,最明显的事件记录在 1993-94、2000-01 和 2006-07 年。显着差异 (p
