particle velocity

In ocean wave studies, the instantaneous velocity of a water particle undergoing orbital motion.

It has the scalar value
ams2001glos-Pe5
where T is the wave period, H the wave height, z the depth below still-water level, and L the wave length. At the crest, its direction is the same as the direction of progress of the wave; at the trough it is in the opposite direction.
See orbital velocity.
