The aim of the session is to describe all aspects of the large-amplitude wave phenomenon in the ocean as the freak, rogue and storm waves; large-amplitude edge and internal waves: dynamical and statistical theories, observations and modelling, numerical simulations in the framework of approximate theories as well as full nonlinear equations. Special attention will be paid to the description of the wave breaking
process, and also large-amplitude wave interaction with coastal structures. The rogue wave phenomenon of any physical nature will be discussed also.
