|Overview||When a steep breaking wave hits a vertical sea wall in shallow water, a rapidly ascending planar jet forms due to the wave impact on the wall and creates what is known as a ‘flip-through’ event. Previous studies focused on the impulsive pressures on the wall and on the velocity of the jet; however, in this study, we considered the formation and break-up of the jet itself. The mechanisms for the sequential surface deformations during the flip-through were identified through a stability analysis and a laboratory experiment, and help to explain the columnar structures often seen in photographs of violent wave impacts on harbour walls.|
