The objective of this research was to analyze the progression of breaker types on plane impermeable slopes. This study used dimensional analysis to demonstrate the relative water depth is a key explanatory quantity. The dominant breaker types depend on the incident wave characteristics at the foot of the slope. Accordingly, it is possible to combine values of H, T, and m. The physical experiments of Galvin, recent numerical results, and new experiments, performed on an impermeable 1:10 slope, were used to verify the result. It was thus possible to obtain the progression of breaker types in different sequences of pairs of combined wave H and T values. Once a sequence is defined, the expected progression of breaker types is predictable, and is well approximated by the log‐transform of the alternate similarity parameter. Since the classification of breaker types is discontinuous, the data assigned to each type were placed in horizontal lines, based on the value of log(χ). Given that the breaking of a wave train on a slope should be considered a continuous process, the location of some data was corrected to satisfy this assumption. There is thus a functional relationship between the sets of the experimental space and of the breaker types. This research also derives the non‐dimensional energy dissipation on the slope, considering the wave‐reflected energy flux on the slope. It is proportional to a dimensionless bulk dissipation coefficient which depends on the breaker type and, therefore, on the value of χ at the toe of the slope.

取决于实验设计的平面不可渗透斜坡上的防波器类型进展

这项研究的目的是分析平面不透水斜坡上破碎锤类型的发展。这项研究使用尺寸分析来证明相对水深是一个关键的解释量。主要的断路器类型取决于斜坡脚下的入射波特性。因此,可以组合H,T和m的值。使用Galvin的物理实验,最新的数值结果以及在不渗透的1:10坡度上进行的新实验来验证结果。因此,有可能在组合的波H和T值对的不同序列中获得断路器类型的变化。一旦定义了序列,断路器类型的预期进展是可预测的,并且可以通过替代相似性参数的对数变换很好地估计。由于断路器类型的分类是不连续的,因此基于log(χ)的值将分配给每种类型的数据放置在水平线上。鉴于应将坡上的波列折断视为一个连续过程,因此对某些数据的位置进行了校正以满足这一假设。因此,实验空间的集合与断路器类型之间存在函数关系。该研究还考虑了斜坡上的波反射能量通量,得出了斜坡上的无量纲能量耗散。它与无量纲的体积耗散系数成比例,该系数取决于断路器的类型,因此也取决于斜率脚趾处的χ值。鉴于应将坡上的波列折断视为一个连续过程,因此对某些数据的位置进行了校正以满足这一假设。因此,实验空间的集合与断路器类型之间存在函数关系。该研究还考虑了斜坡上的波反射能量通量,得出了斜坡上的无量纲能量耗散。它与无量纲的体积耗散系数成比例,该系数取决于断路器的类型,因此也取决于斜率脚趾处的χ值。鉴于应将坡上的波列折断视为一个连续过程,因此对某些数据的位置进行了校正以满足这一假设。因此,实验空间的集合与断路器类型之间存在函数关系。该研究还考虑了斜坡上的波反射能量通量,得出了斜坡上的无量纲能量耗散。它与无量纲的体积耗散系数成比例,该系数取决于断路器的类型,因此也取决于斜率脚趾处的χ值。该研究还考虑了斜坡上的波反射能量通量,得出了斜坡上的无量纲能量耗散。它与无量纲的体积耗散系数成比例,该系数取决于断路器的类型,因此也取决于斜率脚趾处的χ值。该研究还考虑了斜坡上的波反射能量通量,得出了斜坡上的无量纲能量耗散。它与无量纲的体积耗散系数成比例,该系数取决于断路器的类型,因此也取决于斜率脚趾处的χ值。
