项目摘要

In the UK there is a significant amount of infrastructure located at or close to the coast, some of it highly vulnerable to relatively small wave events as well as extreme storm events. Most published coastal studies, and hence guidance documents, are based on the prediction of average quantities such as overtopping rates per hour. Whilst these are undoubtedly useful for estimating drainage requirements and for making flood predictions if the inland drainage is inadequate or becomes blocked, they give little insight into the damage that may be caused by a single extreme overtopping or impulse event, which could cause global structural failure of sea defence works. This project addresses the problem of the most extreme responses at the coast, whether this is wave run-up, overtopping volume or impulse on a section of sea defence works. We aim to understand and model the individual largest and most damaging waves within a long random sequence of severe waves hitting the coast - a storm consisting of thousands of individual waves. We will use the idea of localised groups of large waves to model the most severe waves that arise by chance in a storm. Detailed comparisons will be made between waves in the new flume at Plymouth University and a recently developed computer model OXBOU, all underpinned by analysis of waves at 2 locations off the British coast.

在英国，有大量的基础设施位于或靠近海岸，其中一些非常容易受到相对较小的波浪事件以及极端风暴事件的影响。大多数已发表的海岸研究报告以及指导文件都是基于平均量的预测，例如每小时的漫顶率。虽然这些无疑是有用的估计排水要求和洪水预测，如果内陆排水不足或堵塞，他们给一个极端的漫顶或冲动事件，可能会导致全球结构性破坏的海防工程可能造成的损害的洞察力很少。该项目解决了海岸最极端反应的问题，无论是波浪爬高、越浪量还是海防工程段上的冲量。我们的目标是了解和模拟一个长期的随机序列中最大和最具破坏性的海浪袭击海岸-风暴由数千个单独的海浪组成。我们将使用本地化的大浪组的想法来模拟风暴中偶然出现的最严重的波浪。将在普利茅斯大学新水槽中的波浪和最近开发的计算机模型OXBOU之间进行详细的比较，所有这些都是通过分析英国海岸外2个地点的波浪来支持的。
