Mapping of coastline changes assists in coastal development and monitoring. Athens Riviera, located in the southwestern coastal zone in Attica in central Greece, has undergone major and radical changes generated by human interference during the last decades. The aim of this paper is to map record and measure the coastline changes in Athens Riviera over the past 76 years. Aerial photographs and satellite images from 1945 to 2021 as well as geographic information system (GIS) techniques were used to depict the spatial and temporal variations of the coastline. The results show that 60% of the total length of the coastline is artificial coast, while 29% is rocky coast and 12% beach. The study of seven subareas showed that human interventions caused significant coastline changes in Faliro Bay, Alimos and Glyfada. The adjacent coastal regions to Athens metropolitan area illustrate the highest modifications in the coastline. The main changes in the coastlines are recorded from 1960 to 1987, while the rate of changes in coastline slowed down from 1987 to 2021. The total changes in the coastline of Athens Riviera demonstrate that, during the past 76 years, the coastline was enhanced by 40% while land reclaimed to the sea area approaches 2.67 km². The applied method is effective and rapid and may utilize in the coastal monitoring and management.

雅典里维埃拉海岸线变化图在过去 76 年的测量中

海岸线变化绘图有助于海岸开发和监测。雅典里维埃拉位于希腊中部阿提卡西南沿海地区，在过去的几十年里，由于人为干扰，发生了重大而彻底的变化。本文的目的是绘制记录和测量雅典里维埃拉过去 76 年来的海岸线变化。1945 年至 2021 年的航拍照片和卫星图像以及地理信息系统 (GIS) 技术被用来描绘海岸线的时空变化。结果表明，海岸线总长度的60%为人工海岸，29%为岩石海岸，12%为海滩。对七个分区的研究表明，人为干预导致法利罗湾、阿里莫斯和格利法达的海岸线发生了重大变化。与雅典大都市区相邻的沿海地区说明了海岸线的最大变化。海岸线的主要变化记录在 1960 年到 1987 年，而海岸线变化速度从 1987 年到 2021 年放缓。雅典里维埃拉海岸线的总变化表明，在过去的 76 年中，海岸线增强40% 填海面积接近2.67公里² . 该方法有效、快速，可用于沿海监测和管理。
