For this purpose, data from the laboratory measurements of the wind waves and three components of currents at six horizons in the upper water layer and four different winds, performed in the wind-wave channel of IAP RAS [1, 2], were used. It was established that for a majority of horizons, the frequency spectra, <em>S</em><em><sub>Uz</sub></em>( <em>f </em>), for the vertical component of the flow velocity, <em>U</em><em><sub>z</sub></em>, induced by wind and waves, have the Kolmogorov-type ranges of the kind: Using the algorithms described in [3, 4], this fact allows us to obtain estimates of the TKE-dissipation at the corresponding horizons, and then establish the dependence of on the friction velocity, <em>u</em><sub>*</sub>, the height of waves at the surface, <em>a</em><sub>0</sub>, the peak frequency of the spectrum, <em><sub>p</sub></em>, and the depth of the horizon, <em>z</em>. The analysis of the obtained results allows (for the available data) to propose a parameterization of the form 0.00025 for which a physical interpretation is proposed.</p>windwavescurrentsair-water interfaceturbulenceturbulence dissipation rateветерволнытеченияинтерфейс воздух–водатурбулентностьскорость диссипации турбулентности[Кандауров А.А., Троицкая Ю.И., Сергеев Д.А., Вдовин М.И., Байдаков Г.А.
