Flooding scenario for four Italian coastal plains using three relative sea level rise models

The coastal areas of the central Mediterranean Sea are sensitive to climate change and the consequent relative sea level rise. Both phenomena may affect densely urbanized and populated areas, causing severe damages. Our maps show the land-marine flooding projections as effects of the expected relative sea level rise for four Italian coastal plains using (i) IPCC AR5 estimations, based on the IPCC RCP 8.5 emission scenarios and (ii) the Rahmstorf 2007 model. Isostatic and tectonic data were added to the global projections to estimate the relative sea changes expected along the coastline by 2100, as well as sea-flooding. The northern Adriatic map shows the study area, extending for about 5500 km², and is presented at a scale of 1:300,000 with two inset maps at a scale of 1:150,000. The Oristano coastal plain is about 125 km²; the map scale is at 1:60,000 with an inset map scale at 1:33,000. The Cagliari coastal study area extends for 61 km²; the map scale is at 1:60,000 with two inset maps at 1:30,000. The Taranto area extends for 4.2 km² and is represented at a scale map of 1:30,000, while the three inset maps are at a scale of 1:10,000.

地中海中部沿海区域对气候变化及由此引发的相对海平面上升极为敏感。上述两类现象均会对人口稠密、城镇化程度较高的区域造成影响，并可能引发严重损失。本数据集的地图展示了意大利4处沿海平原受预期相对海平面上升影响的陆海淹没预测情景，其计算依据分别为：（i）政府间气候变化专门委员会（IPCC）第五次评估报告（AR5）基于RCP 8.5排放情景得出的估算结果，以及（ii）拉姆斯托夫（Rahmstorf）2007年模型。为估算截至2100年该海岸沿线的相对海平面变化与海洋淹没范围，研究团队在全球海平面变化预测数据中加入了均衡地壳运动与构造运动相关数据。北亚得里亚海地图展示了本次研究区域（总面积约5500平方千米），主图比例尺为1:300000，并附带2幅比例尺为1:150000的附图。奥里斯坦诺沿海平原面积约125平方千米，主图比例尺为1:60000，附带1幅比例尺为1:33000的附图。卡利亚里沿海研究区域面积为61平方千米，主图比例尺为1:60000，附带2幅比例尺为1:30000的附图。塔兰托区域面积为4.2平方千米，主图比例尺为1:30000，附带3幅比例尺为1:10000的附图。
