Abstract
This paper is aimed to investigate the pertinent characteristics of velocity field of nonlinear crossing waves in finite water depth, based on the laboratory experiments and the 3rd-order crossing wave theory. The 3rd-order crossing wave theory is shown to estimate well the experimental results. In case that the directions of two wave trains are different, the velocity direction of crossing waves is different in water surface and bottom. In addition, the skewness of water particles of crossing waves is fairly affected by each wavelength of two wave trains and crossing angle.
