碩士 / 國立成功大學 / 水利及海洋工程學系碩博士班 / 98 / This study experimentally investigates the dynamics of solitary wave propagating over a breakwater, including the overtopping, the impact of square structure and the related run-up. Three wave steepness and different positions of square structure behind the breakwater were tested to examine characteristics of overtopping. The PIV system and pressure sensors were used to measure the velocity field and pressure distribution, respectively. The wave energy dissipation, run-up energy, impact pressure distribution and time series of pressure are presented. Finally, the location maximum pressure caused by different wave steepness and relative positions of structure are also discussed.
The results found that the overtopping type is much different at various water depths with fixed wave steepness. However, all overtopping types and wave steepness have roughly same trend. In addition, there is a negative relationship between the impact pressure and the square structure distance, whereas there is a positive relationship between the impact pressure and the wave steepness.
