ABSTRACT

The design of the new protection scheme in the Eforie’s area was done based on yearly averaged incident waves from the dominant NE wave energy direction, with associated preferred coastline, which agrees well with a natural behavior of the present shoreline. The sand nourishments were constructing the new overall orientation of the computed shoreline, now in post-construction period corresponding to a new orientation of the coastline. The present work presents the functional effectiveness of the model simulation for the existing hydro-morphological development patterns, together with the calculations of the erosion rates and adjacent effects of the structures, such as the submerged breakwaters and the groins extensions, contributing to the compensation annual rates for maintenance of the artificial beach extension in this sector. Thus, the contribution of the extreme events/winter wave’s regime to the calculation of the average sediment loss, in the southern adjacent area to the Constanta Port, requires an annual maintenance for correction.
