Then you might try changing the period to 2 secs. The water particle velocities under linear waves are maximum at the surface and decrease in magnitude with depth. In shallow water, the elliptical paths followed by the water particles flatten to horizontal lines, particularly at the bottom, where no vertical flow is allowed into the bottom. The directions of the particle velocities are related to the motion of the water surface and the local velocity vectors are shown within their elliptical orbital paths in the panel. At the crest of the wave, the water motion is horizontal and in the direction of the wave.
Vertical velocities reach their maxima when the still water crossings occur.
Note that this figure is distorted.
