A numerical analysis was performed to analyze the solitary wave control mechanism of a submerged horizontal plate (SHP). A two-dimensional numerical wave tank (NWT), which uses a wave generation method that generates a stable solitary wave, was employed for the numerical analysis. To verify the effectiveness of the NWT, the waveform measured around the SHP was compared to the calculated waveform. Moreover, the approximate and the calculated waveforms were compared in order to examine whether the solitary wave was stably generated. The results of comparison and verification showed that the deformation of the solitary wave by SHP was reproduced with high accuracy in the calculation, while the calculated waveform of NWT also showed a high degree of matching with the approximate waveform. The solitary wave breaking on the SHP satisfied the existing threshold condition A 0 /h c > 0.827-0.833, but breaking did not occur even under the condition A 0 /h c ＝1.2 when the width of the SHP was small. Accordingly, the wave height attenuation of the solitary wave occurred rapidly in a breaking condition. In a non-breaking condition, the energy gradually decreased due to the vorticity and turbulence around the boundary of the SHP, resulting in a gradual attenuation of the solitary wave.

In this study, hydraulic experiments were performed for three types of cross sections depending on the presence or absence of pipeline of CTSB(Caisson-Type Submerged Breakwater), in which slit-upper-level drainage and lower-level drainage are installed to reduction the water level behind the submerged breakwaters. Additionally, based on the measured hydraulic characteristics, we compared the changes in the wave reflection, transmission and dissipation coefficient around the submerged breakwaters three cases with or without drainage with a solid caisson that has no slit-upper-level and lower-level drainage. Therefore, wave control around the submerged breakwaters is better using the Caisson-Type solid than with the slit-upper-level drainage and lower-level drainage. Moreover, reduction of water level behind the submerged breakwaters is better using the slit-upper-level drainage and lower-level drainage than Caisson-Type solid. its effect is excellent when with TTP are used.
