ABSTRACT The Evros deltaic plain (North Aegean Sea, Greece) covers an area of 188 km2 and is shared by Greece and Turkey by its current main channel. This paper investigates deltaic plain evolution during the last seven decades (1945–2017), taking into consideration human interventions and their impacts on deltaic processes. Outcomes indicate that the construction of more than 25 major dams in the Evros River catchment resulted in >80% reduction in fluvial suspended load. Moreover, the alignment and relocation of the main distributary channel to the southeast was accompanied by the transformation of >40% of the deltaic plain to agricultural land. The combination of human interventions supports the coastline advance of the active main mouth (current rate of 3.9 *10−3 km2/yr), retreat of the old (abandoned) Evros mouth (current rate 7.7 *10−3 km2/yr), and signs of remarkable vulnerability in the middle mouth area.

人类干预下跨界埃夫罗斯河三角洲（东北爱琴海）的演变：七年分析

摘要 埃夫罗斯三角洲平原（希腊北爱琴海）面积 188 平方公里，由希腊和土耳其通过其现有的主要航道共享。本文调查了过去七年（1945-2017 年）的三角洲平原演化，同时考虑了人类干预及其对三角洲过程的影响。结果表明，在埃夫罗斯河集水区建造了超过 25 座大坝，使河流悬浮荷载减少了 80% 以上。此外，主要分流河道向东南的调整和搬迁伴随着>40%的三角洲平原向农用地转变。人为干预的组合支持活动主河口的海岸线前进（当前速度为 3.9 * 10−3 平方公里/年），旧（废弃）埃夫罗斯河口后退（当前速度为 7.
