The on-offshore and the vertical components u, w of the velocity in a surf zone on a uniformly sloping beach in a wave tank were measured simultaneously with a laser-doppler velocimeter under two conditions.The time variation of the Reynolds stress -u'w' during one wave period is discussed.The Reynolds stress behaves as that in the oscillatory pipe flow does.The magnitude of the terms including the Reynolds stress terms in the on-offshore momentum equation is estimated.The Reynolds stress terms does not play any important role in the on-offshore momentum transfer during one wave period in the surf zone.

By a flow visualization of a plunging breaker on 1/20 slope beach in a wave tank, an existence of 2nd and 3rd horizontal vortices(Miller, 1976) and slanting vortex (Nadaoka et al., 1986) is confirmed. A MAC method is applied to simulate a violent motion after an impinging of a jet from a crest of a plunging breaker on the trough surface. The calculated maximum water particle velocity in the jet is found to reach three times the linear long wave celerity. Values of circulation of the first four horizontal vortices are calculated and their changes in time are discussed.

“…Sakai et al [ 11 ] found that the turbulent intensity varies more in the case of a transient breaker between spilling and plunging than in the case of a spilling breaker. In the latter case, the turbulent intensity is not damped so much as the waves propagate in the surf zone.…”
