研究了孤立波与垂直圆柱的非线性相互作用。测量了圆柱附近不同位置的波浪场，讨论了波浪的反射、绕射和散射的详细过程。第一和第二散射波的形成分别在入射波第一次遇到圆柱体时和在其离开圆柱体时观察到。比较广义Boussinesq（GB）模型被发现给相当好的结果，波高，除了非常接近的圆柱体表面，并在圆柱体后面的直接唤醒区域。在入射波的传播方向上的圆柱上的净力作为时间的函数进行测量，并得到良好的协议与gB模型。
The nonlinear interaction of a solitary wave and a vertical circular cylinder is examined. The wave field was measured at various locations near the cylinder and the detailed process of wave reflection, diffraction and scattering is discussed. The formation of the first and second scattered wave is observed as the incident wave first encounters the cylinder and as it leaves the cylinder respectively. Comparisons are made to the generalized Boussinesq (gB) model which is found to give quite good results for the wave heights except very close to the cylinder surface and in the immediate wake region behind the cylinder. The net force on the cylinder in the direction of incident wave propagation was measured as function of time, and good agreement with the gB model is obtained.
