In this review paper, the main geometrical characteristics of sea ripples (the smallest morphological patterns that are observed at the bottom of sea waves) are reviewed together with the physical mechanisms that give rise to their appearance and control their time development. Moreover, we provide a summary of both the mathematical tools (stability analyses) and empirical formulae that can be used to predict their appearance and some of their geometrical characteristics. The ripples play a relevant role in the mechanics of coastal sediment transport since usually the flow separates at the ripple crests and generates vortex structures that pick-up the sediments from the bottom and put them into suspension. Moreover, the vortex structures shed by the ripples significantly affect wave damping and flow resistance.

海浪底部沙波纹特征的预测

在这篇综述论文中,回顾了海波纹(在海浪底部观察到的最小形态图案)的主要几何特征以及引起其出现和控制其时间发展的物理机制。此外,我们还提供了数学工具(稳定性分析)和经验公式的总结,可用于预测它们的外观和一些几何特征。波纹在沿海沉积物输送的力学中发挥着重要作用,因为通常水流在波纹波峰处分离并产生涡流结构,从底部拾取沉积物并使它们悬浮。此外,波纹脱落的涡流结构显着影响波浪阻尼和流动阻力。
