Abstract: The velocity and acceleration of water particles near the nodes, and the wave pressure on the breakwater for full and partial standing waves are measured in a wave flume. The results of experiment are analyzed systematically. The measured maximum of velocity, time history of velocity and acceleration are compared with theoretical ones in order to ascertain the range in which each typical theory is available. The effect of partial standing wave on kinematic characteristics of water particles is also discussed. Based on the analysis of the dynamical characteristics of the standing wave, a new method is introduced to analyze the wave pressure with nonlinear properties. The results of this method are compared with those of experiment and Fourier series approximation theory. It is proved to have almost the same precision as Fourier series approximation. But its operation is much simpler than the latter's.
