估计海岸线上极端海平面的概率的问题几乎没有受到关注。现有的大多数分析都是单变量方法，独立地应用于各个站点的数据。我们提出了一种方法的空间扩展，该方法整合了来自数据站点的信息，并利用海岸线上海平面潮汐和潮汐分量的空间变化知识来产生任何沿海位置的估计。我们通过对英国东海岸的应用来说明该方法，并提供了整个海岸线的一组设计水平估计。
The problem of estimating the probability of extreme sea-levels along a coastline has received little attention. Most of the existing analyses are univariate approaches that are applied independently to data from individual sites. We present a spatial extension of the methods that integrates information from the data sites and exploits knowledge of the spatial variation of the tidal and surge constituents of the sea-level along a coastline, to produce estimates at any coastal location. We illustrate the method by application to the UK east coast providing a set of design level estimates along the entire coastline.
