通过波浪槽中的光滑潜堤试验研究，探讨了波浪通过潜堤时，潜堤对典型波浪周期变化的影响。波浪周期的缩短与波陡和相对淹没Rc/Hm 0 −i有很强的关系。此外，还研究了波浪通过光滑潜堤时对瑞利波高分布的影响。研究了光滑结构物淹没后产生的长短波对时域分析的影响。Lanczos滤波器用于去除高频和低频波。得出的结论是，长波和短波不显着影响时间分析的周期。货车der梅尔等人（2000年）描述透射光谱的模型已得到改进，因此它与测量结果更好地吻合。假设能量从较低频率向较高频率的传递随着相对淹没度-Rc/Hm 0的减小而线性消失。传递到较高频率的能量被假设为均匀分布在1.5fp和3.2fp之间。
Based on the experimental studies of smooth submerged breakwater in the wave channel, it has been studied how the breakwater impacts on the changes of representative wave periods when the waves cross the breakwater. It has been shown that the reduction of the wave periods has a strong relationship with the wave steepness and relative submersion Rc/Hm0−i. Also, the impact of waves crossing the smooth submerged breakwater onto the Rayleigh's distribution of wave heights was investigated. The influence of short and long waves generated after submerged smooth structure on temporal analysis has been investigated. The Lanczos filter was used for high and low frequency wave removal. It was concluded that long and short waves do not significantly influence the temporal analysis of periods. The Van der Meer et al. (2000) model for the description of the transmitted spectrum has been improved so it gives better agreement with measurements. It was assumed that transfer of the energy from lower to higher frequencies vanishes linearly with a decrease in the relative submergence −Rc/Hm0. The energy transferred to higher frequencies is assumed as uniformly distributed between 1.5fpand 3.2fp.
