We will first present a two-dimensional study of the interaction of finite-amplitude incident periodic waves with a linearly sloping boundary over 3 wave periods for different values of wavelengths, Froude numbers and stratification choices. We will highlight the importance of the choice of the sea-bed boundary condition (no-slip/free-slip) in the breaking mechanisms. We will also present the preliminary results of three-dimensional simulations of internal-wave-induced transition to turbulence on the sloping boundary.
