The marine storms take place with a relatively high frequency at the Romanian Black Sea coast characterized by an active storm regime, especially in the winter times, when the reported values of wind speed at gust reach 40 m/s, producing the offshore waves high of 5-8 m and even more in the offshore area. Even the frequency of storm surges at the western Black Sea shore is relatively low comparing to other European seas, the North-East occurrence of such storms produces significant exposures. Due to the magnitude of the storm surges, the sea level is settled at 7 or 8 times higher than the average changes occurring for the sea level, due to other factors. In the present work was developed a complex approach to highlight the effect of waves penetration associated with storm surges with long-term return periods reported for the area of the Romanian maritime ports. A study was carried out, focusing on the variation of the long waves’ penetration in ports’ basins, recorded as water level at the effective gauging stations. Therefore, trapped waves producing variations of up to 1.3 m have been revealed. As part of the present evaluation, the return periods of such coastal threats were calculated to determine the extreme conditions required in the modeling approach on marine hydrodynamic processes, encompassed in a complex study of seiches’ impact on port management activities, during the hydrologic events comprise on data series provided by European Center for Medium Term Forecast for an interval of a decade (1991 - 2002), with continuous recordings supervised in-situ by human observers.
