本文分析了文献中不同的波高概念，讨论了设计波高确定中的一些常见问题，如参数模型的选择和估算。本文分析了波浪资料拟合的常用方法（峰值法、超阈值峰值法、年最大值法等），并指出了一些常用分布存在的问题。对有效波高设计值的使用进行了分析和讨论。结果表明，显着的波高几乎没有个人的信息，尾部行为的波高和个人波高提出作为一种替代。本文提出了用广义帕累托分布拟合高阈值波高比的方法，并给出了估计方法。最后，科迪亚克数据集作为一个例子来说明的方法。
This paper analyses different wave height concepts used in the literature and discusses some common problems associated with the determination of design wave heights, such as selection of parametric models and estimation. The authors analyze common methods (peak values, peaks over a threshold, yearly maximum, etc) used in fitting wave data and point out the problems associated with some of the commonly used distributions. The use of significant wave heights for design values is analyzed and discussed. It is shown that significant wave heights have practically no individual information about the tail behaviour of wave heights and individual wave heights are proposed as an alternative. The use of the generalized Pareto distribution for fitting wave height exceedances over high thresholds is proposed and justified and an estimation method is given. Finally, the Kodiak data set is used as an example to illustrate the methodology.
