We assess the relative vulnerability of the Mediterranean shoreline of Egypt (about 1000 km in length) to climate change (i.e., sea‐level rise [SLR], storm surge flooding, and coastal erosion) by using a Climate‐improved Coastal Vulnerability Index (CCVI). We integrate information relative to a multidimensional set of physical, geological, and socioeconomic variables, and add to the mainstream literature the consideration of both a reference and a climate change scenario, assuming the representative concentration pathway 8.5 W/m² (RCP8.5) for the 21st century in the Mediterranean region. Results report that approximately 1% (~43 km²) of the mapped shoreline is classifiable as having a high or very high vulnerability, whereas approximately 80% (4652 km²) shows very low vulnerability. As expected, exposure to inundation and erosion is especially relevant in highly developed and urbanized coastal areas. Along the shoreline, while the Nile Delta region is the most prone area to coastal erosion and permanent or occasional inundations (both in the reference and in the climate scenario), results show the Western Desert area to be less vulnerable due to its geological characteristics (i.e., rocky and cliffed coasts, steeper coastal slope). The application of the CCVI to the coast of Egypt can be considered as a first screening of the hot‐spot risk areas at the national scale. The results of the analysis, including vulnerability maps and indicators, can be used to support the development of climate adaptation and integrated coastal zone management strategies.

埃及沿海地区对海平面上升和风暴潮的脆弱性：现在和将来的状况。

我们通过使用气候改善的沿海脆弱性指数（约1000公里长），评估了埃及地中海海岸线（约1000公里）对气候变化（即海平面上升[SLR]，风暴潮洪水和沿海侵蚀）的相对脆弱性（ CCVI）。我们整合与物理，地质和社会经济变量的多维集有关的信息，并在假设代表性浓度路径为8.5 W / m ^2的情况下，将参考文献和气候变化情景的考虑都添加到主流文献中。（RCP8.5）在地中海地区的21世纪。结果报告指出，大约1％（〜43km²）的地图海岸线可归类为高度脆弱性或非常高的脆弱性，而大约80％（4652km²）的脆弱性极低。不出所料，在高度发达和城市化的沿海地区，浸水和侵蚀尤为重要。沿海岸线，虽然尼罗河三角洲地区是沿海侵蚀和永久性或偶发性洪水最容易发生的地区（在参考资料和气候情景中），但结果表明，西部沙漠地区由于其地质特征而较不易受到侵害（即多岩石的和陡峭的海岸，陡峭的沿海坡度）。CCVI在埃及沿岸的应用可以被认为是对全国范围内热点地区的首次筛选。Integr环境评估管理2020； 16：761-772。©2020 SETAC
