     1237Surface waves produce an enhanced mixing through wave-turbulence interaction. 
     1238In addition to breaking waves induced turbulence (\autoref{subsec:ZDF_tke}), 
     1239the influence of non-breaking waves can be accounted introducing  
     1240wave-induced viscosity and diffusivity as a function of the wave number spectrum. 
     1241Following \citet{qiao.yuan.ea_OD10}, a formulation of wave-induced mixing coefficient 
     1242is provided  as a function of wave amplitude, Stokes Drift and wave-number: 
     1243 
     1244\begin{equation} 
     1245  \label{eq:Bv} 
     1246  B_{v} = \alpha {A} {U}_{st} {exp(3kz)} 
     1247\end{equation} 
     1248 
     1249Where $B_{v}$ is the wave-induced mixing coefficient, $A$ is the wave amplitude,  
     1250${U}_{st}$ is the Stokes Drift velocity, $k$ is the wave number and $\alpha$  
     1251is a constant which should be determined by observations or  
     1252numerical experiments and is set to be 1. 
     1253 
     1254The coefficient $B_{v}$ is then directly added to the vertical viscosity  
     1255and diffusivity coefficients. 
     1256 
     1257In order to account for this contribution set: \forcode{ln_zdfswm = .true.}, 
     1258then wave interaction has to be activated through \forcode{ln_wave = .true.}, 
     1259the Stokes Drift can be evaluated by setting \forcode{ln_sdw = .true.}  
     1260(see \autoref{subsec:SBC_wave_sdw}) 
     1261and the needed wave fields can be provided either in forcing or coupled mode 
     1262(for more information on wave parameters and settings see \autoref{sec:SBC_wave})
