These modes have obviously oscillations in temporal domain, in which the foreshore mode has mainly quasi period about 4 days, while the quasi period for the beach berm mode is 2 8 days.
空间模式在时域上具有一定的振荡周期。其中，前滨模式以4天的准周期变化为主，滩肩模式则有2 8天的准周期性变化。
The report takes account into the influence of foreshore and shallow foreshore, roughness, slope, berm, wave attack Angle, vertical wall and so on.
报告给出了复杂断面上波浪爬高和越浪量的计算公式，计算中考虑了前滩、边坡糙率、边坡坡度、平台、波浪入射角以及竖墙等因素的影响。
