开敞水域波浪的传播——抛物线方程法

Parabolic Equation Approximate Method for Calculation of Wave Propagation in Open Sea Area

本文介绍了用抛物线方程法计算波浪传播的算法。该方法是应用缓坡方程,忽略其水下地形对波浪反射的影响来进行波浪折射、绕射联合计算的。它克服了常法中不能考虑的波能沿波峰方向传输的局限性。

This paper presents the calculation of wave propagation by parabolic equa-tion approximate method, in which the combined calculation of ref raction-di ffraction of wave propagation is carried out over a mild sloping topography anb neglecting the influence of underwater topography to the wave reflection. This method has the advantage of over-coming the deficiency existed in the conventional method, in which the transmission of wave energy along the wave crest direction will not be considered.
