溢流是受风暴事件驱动的海岸泥沙运移的物理过程，对低洼屏障环境中的景观弹性至关重要。这项工作为溢流形态建立了一套全面的标度定律：统一了定量描述，用于通过案例示例的形态属性来比较溢流特征。这样的比例定律也有助于将溢流特征与其他地貌动力学现象联系起来。在这里，来自物理实验的形态测量数据与来自溢流特征的自然例子的数据进行了比较。由此得到的比例关系表明在几个数量级范围内的比例不变性。此外，这些新的溢流形态关系符合河流排水和冲积扇的经典比例定律。
Overwash is a physical process of coastal sediment transport driven by storm events and is essential to landscape resilience in low‐lying barrier environments. This work establishes a comprehensive set of scaling laws for overwash morphology: unifying quantitative descriptions with which to compare overwash features by their morphological attributes across case examples. Such scaling laws also help relate overwash features to other morphodynamic phenomena. Here morphometric data from a physical experiment are compared with data from natural examples of overwash features. The resulting scaling relationships indicate scale invariance spanning several orders of magnitude. Furthermore, these new relationships for overwash morphology align with classic scaling laws for fluvial drainages and alluvial fans.
