本文综述了计算海浪在陆冰边界反射和透射率的各种数值方法，包括最近的发展。虽然通过Wiener-Hopf技术找到的解的积分形式已经知道很多年了，但对这个精确解的直接数值计算被认为是非常困难的。取而代之的是，发展了几个数值“匹配”程序，包括一些仅是近似的程序，以及基于积分形式的渐近解。最近发现，直接计算积分形式是可行的，实际上比匹配方法需要更少的计算量。我们概述了所需的实际计算，并对每种方法进行了比较，并提供了从积分形式进行计算的例子。
Abstract We review the various numerical methods that have been developed for calculating the reflection and transmission of ocean waves at a land-fast ice boundary, including recent developments. While an integral form of the solution, found by the Wiener-Hopf technique, has been known for many years, direct numerical computation of this exact solution has been thought to be prohibitively difficult. Instead, several numerical "matching" procedures have been developed, including some that are only approximate, along with asymptotic solutions based on the integral form. Recently it has been discovered that direct calculation of the integral form is feasible, actually requiring less computation than the matching methods. We outline the actual computations required and contrast each method, and provide examples of computation from the integral form.
