Abstract: The research on the nonlinearity of nearshore water waves has a significant meaning in helping us to understand the physical characteristics of nearshore waves and currents, to utilize nearshore marine resources, and to assist the decision-making process of the hazard prediction and mitigation. In recent years, many new nonlinear nearshore wave equations were developed. However, because different processes have different topographical conditions and roughness, they adapt to different governing equations. It is necessary to know the application scopes and calculation efficiencies of the main nonlinear wave equations. This paper reviews the methods of nonlinearity classification and reviews the main nonlinear wave models and their applications for nearshore regions, including their physical properties and the degree of nonlinearity. This paper will help researchers to understand the nonlinearity of different nearshore issues and to choose a suitable simulation model.

Key words: nonlinearity, mathematical model, governing equations, water waves
