The extreme flash-flood of November 2017 in Western Attica, Greece, caused severe damages not only in the landward area, but also in the adjacent marine environment. The study of a number of data, such as visual observations immediately after the catastrophic event, a series of satellite images that demonstrate the movement of the flood-related suspended material, and comparative elemental and hydrocarbon geochemical analyses between the fresh, recently deposited sediments, and the older ones, have shown that an extended part of the Elefsis Bay, particularly the northeastern sector, has experienced a severe modification in its sedimentary and geochemical status, that may have irreversibly affected the already environmentally degraded marine ecosystem of the area.

洪水对邻近海洋环境的影响：希腊曼德拉（Mandra）和尼亚·佩拉莫斯（Nea Peramos）（2017年11月）

2017年11月，希腊西部阿提卡爆发了特大洪灾，不仅对陆上区域造成了严重破坏，而且对邻近的海洋环境造成了严重破坏。研究了大量数据，例如在灾难性事件发生后立即进行肉眼观察，一系列卫星图像显示洪水相关悬浮物的运动以及比较新鲜的，最近沉积的沉积物之间的元素和碳氢化合物地球化学分析，较旧的数据表明，Elefsis湾的一部分，特别是东北部地区，其沉积和地球化学状况发生了严重变化，可能不可逆转地影响了该地区已经环境退化的海洋生态系统。
