Waves represent the most important factor in the evolution of the coastal zones. One of the main causes leading to the wave formation is the movement of the air masses. A particular influence on the wave agitation regime in the littoral sector is exerted by the shore configuration, water depth, bottom relief and the formation of ice cover in winter. The scope of this paper is to analyze the historical data on the wind and waves in the Danube discharge area. The emphasis is on the maximum values of wave heights and the insurance curves resulting from calculations, in the maritime sector of the Danube Delta. The research incorporates data from Jibrieni, Snake Island and Sulina stations, covering a timeframe of 5 years. Observation data have been processed and presented in order to generate an overall picture of these phenomena that affect the spatial unfolding of the shore. Furthermore, of a particular importance in the calculations is determining the correlations between wind speeds and wave height. The results suggest that the characteristics of the waves acquire significant values. This knowledge can be utilized in designing marine vessels or hydrotechnical structures. During the extreme events, storm-induced waves and the sea level are key factors in the evolution of the shore. The coastline response to these conditions takes into account the characteristics of the storm (intensity, direction and duration). In this respect, the hypothesis of the waves in the development stage was used, analyzing for each different wind direction the wind speed in correlation with wave height values. In conclusion, the present paper offers an overview of the wave characteristics in the maritime sector under different wind conditions.
