The main mechanisms of air entrainment by breaking waves are spilling breakers and plunging breakers. With plunging breakers, the entrainment of air bubbles is caused by the top of the wave forming a plunging jet and entraining air when it impacts the water in front of the wave. The potential for air bubble entrainment is much greater than the spilling wave type. New experiments were performed in a two-dimensional wave basin. The breaking process was investigated with a high-speed video camera. The results provide new information on the breaking point characteristics, the jet impact conditions and the energy dissipation process. The entrainment of air bubbles is detailed. And the rate of energy dissipation by plunging breakers is estimated. The interactions between air bubble entrainment and energy dissipation mechanisms are discussed.
