论文摘要
为了准确预测近海波的后果，沿海工程师经常采用数值模型。这些模型的各种模型被广泛归类为相位分辨率或相平均的模型；每个过程都具有力量和局限性，这是由于其内部过程的物理示意图。解决垂直流结构或全波谱的模型（即Sea-Swell（SS）和Instragravity（Ig）波）被认为更准确，但比具有近似值的模型更准确，但计算要求更高。在这里，我们评估了在浅境条件下的六个著名波浪模型（Q）的六个著名波浪模型的速度准确性权衡。结果表明：i）q被忽略时被IG波的数量级低估； ii）使用更多的计算要求模型不能保证更准确的结果； iii）有了经验校正来解释IG波，像天鹅这样的相平均模型可以在PAR上执行，甚至比相位分辨率模型更好，但计算努力却少得多。
To accurately predict the consequences of nearshore waves, coastal engineers often employ numerical models. A variety of these models, broadly classified as either phase-resolving or phase-averaged, exist; each with strengths and limitations owing to the physical schematization of processes within them. Models which resolve the vertical flow structure or the full wave spectrum (i.e. sea-swell (SS) and infragravity (IG) waves) are considered more accurate, but also more computationally demanding than those with approximations. Here, we assess the speed-accuracy trade-off of six well-known wave models for overtopping (q), under shallow foreshore conditions. The results demonstrate that: i) q is underestimated by an order of magnitude when IG waves are neglected; ii) using more computationally-demanding models does not guarantee more accurate results; and iii) with empirical corrections to account for IG waves, phase-averaged models like SWAN can perform on par, if not better than, phase-resolving models but with far less computational effort.
