PLUNGING WAVES IN THE INNER SURF ZONE AND BURGERS-LIKE TURBULENCE

In this study we especially examine the turbulent energy spectra of two laboratory waves, a plunging one and a spilling-plunging one in the inner surf zone, with the aim to verify if Burger’s turbulence model can be applied, especially considering that it is used in situations where the one-dimensional approximation is deemed appropriate, In detail, we investigate how turbulent energy spreads and dissipates involving different length scales in the inertial and diffusive range. It is worth remarking that applying relations of Burgers turbulence could lead to modelling simplifications and easier mathematical solutions, in the prediction of wave energy dissipation in the inner surf zone. This is a valuable result in our opinion.
