项目摘要

Rising mean sea levels threaten many low-lying coastal areas in many ways, including raising extreme sea-level events. Extreme sea-level events can give rise to serious coastal flooding and erosion. The Netherlands is especially vulnerable to sea level rise and coastal flooding and erosion, as approximately 50% of its land area is less than 1 m above mean sea level. Netherlands literally means 'lower countries'. Today, almost half of the Netherlands' 17 million inhabitants live along its 350 km coast or in regions which are near to or below mean sea level.Across the Netherlands, six storm surge barriers form an important part of the Delta Works, which protects large areas of land from flooding. Storm surge barriers are moveable flood gates or barriers at estuaries, tidal inlets and river mouths which close, automatically or otherwise, when water levels are extremely high. With the rate of mean sea level rise projected to accelerate over the remainder of the 21st century and beyond, it is expected the storm surge barriers will need to close more and more regularly, with important implications for operation, management and maintenance windows. This PhD project will assess past and future closures of the storm surge barriers in the Netherlands and explore implications for the Thames Barrier, the new Venice Barrier, and other barriers around the world.

平均海平面上升在许多方面威胁着许多低洼沿海地区，包括极端海平面上升事件。极端的海平面事件可能导致严重的沿海洪水和侵蚀。荷兰特别容易受到海平面上升和沿海洪水和侵蚀的影响，因为其约50%的土地面积高于平均海平面不到1米。荷兰的字面意思是“较低的国家”。今天，荷兰1 700万居民中几乎有一半生活在沿着350公里的海岸线或接近或低于平均海平面的地区，在荷兰各地，六个风暴潮屏障是三角洲工程的重要组成部分，它保护大片土地免受洪水侵袭。风暴潮屏障是位于河口、潮汐入口和河口的可移动防洪闸或屏障，当水位极高时，它们会自动或以其他方式关闭。随着预计在21世纪剩余时间及以后平均海平面上升速度加快，预计风暴潮屏障将需要越来越经常地关闭，这对运行、管理和维护窗口产生重要影响。该博士项目将评估荷兰风暴潮屏障过去和未来的关闭情况，并探索对泰晤士河屏障，新威尼斯屏障和世界各地其他屏障的影响。
