Hasselmann and coauthors proposed the discrete interaction approximation (DIA) as the best tool replacing the nonlinear evolution term in a numerical wind–wave model. Much later, Polnikov and Farina radically improved the original DIA by means of l

The problem of assessing the risk for a vessel to encounter a killer wave in the Black Sea is considered. Analysis of in situ wave data obtained from the platform of Marine Hydrophysical Institute in the autumn of 2009 shows that occurrence frequency

Empirical relations for the wind-induced drift current, Ud, measured at a wavy water surface in a laboratory and in the field, are presented and discussed. A relatively large value of Ud with respect to the friction velocity in water is highlighted,

Results of measurements of the drift currents induced by waves and wind at the wavy water surface are presented. The measurements were executed by means of surface floats in a large tank with the dimensions of 32.5x1x2 m3. Three cases were studied: (

In the paper a new version of semi-phenomenological model is constructed, which allows to calculate the friction velocity u* via the spectrum of waves S and the wind at the standard horizon W. The model is based on the balance equation for the moment
