The coasts of the Mediterranean Sea are dynamic habitats in which human activities have been conducted for centuries and which feature micro-tidal environments with about 0.40 m of range. For this reason, human settlements are still concentrated along a narrow coastline strip, where any change in the sea level and coastal dynamics may impact anthropic activities. In the frame of the RITMARE and the Copernicus Projects, we analyzed light detection and ranging (LiDAR) and Copernicus Earth Observation data to provide estimates of potential marine submersion for 2100 for 16 small-sized coastal plains located in the Italian peninsula and four Mediterranean countries (France, Spain, Tunisia, Cyprus) all characterized by different geological, tectonic and morphological features. The objective of this multidisciplinary study is to provide the first maps of sea-level rise scenarios for 2100 for the IPCC RCP 8.5 and Rahmstorf (2007) projections for the above affected coastal zones, which are the locations of touristic resorts, railways, airports and heritage sites. On the basis of our model (eustatic projection for 2100, glaciohydrostasy values and tectonic vertical movement), we provide 16 high-definition submersion maps. We estimated a potential loss of land for the above areas of between about 148 km2 (IPCC-RCP8.5 scenario) and 192 km2 (Rahmstorf scenario), along a coastline length of about 400 km.

2100 年地中海 16 个沿海平原的相对海平面上升和潜在的淹没风险

地中海沿岸是动态的栖息地,人类活动已在其中进行了几个世纪,具有范围约为 0.40 m 的微潮汐环境。出于这个原因,人类住区仍然集中在狭窄的海岸线地带,海平面和海岸动态的任何变化都可能影响人类活动。在 RITMARE 和哥白尼项目的框架内,我们分析了光探测和测距 (LiDAR) 和哥白尼地球观测数据,以提供对位于意大利半岛和四个地中海国家的 16 个小型沿海平原 2100 年潜在海洋淹没的估计(法国、西班牙、突尼斯、塞浦路斯)都具有不同的地质、构造和形态特征。这项多学科研究的目的是为 IPCC RCP 8.5 和 Rahmstorf (2007) 预测提供 2100 年海平面上升情景的第一张地图,这些沿海地区是旅游胜地、铁路、机场和遗产地。根据我们的模型(2100 年的静海投影、冰川静水值和构造垂直运动),我们提供了 16 幅高清淹没图。我们估计上述地区的潜在土地损失在大约 148 平方公里(IPCC-RCP8.5 情景)和 192 平方公里(Rahmstorf 情景)之间,沿着大约 400 公里的海岸线长度。根据我们的模型(2100 年的静海投影、冰川静水值和构造垂直运动),我们提供了 16 幅高清淹没图。我们估计上述地区的潜在土地损失在大约 148 平方公里(IPCC-RCP8.5 情景)和 192 平方公里(Rahmstorf 情景)之间,沿着大约 400 公里的海岸线长度。基于我们的模型(2100 年的静海投影、冰川静水值和构造垂直运动),我们提供了 16 幅高清淹没图。我们估计上述地区的潜在土地损失在大约 148 平方公里(IPCC-RCP8.5 情景)和 192 平方公里(Rahmstorf 情景)之间,沿着大约 400 公里的海岸线长度。
