Resumen
This study for overtopping reduction in crownwall design presents several results of 2D (wave flume) and 3D (wave basin) tests on irregular wave overtopping of different configurations for breakwater sections were obtained by the Applied Hydrodynamics Institute (INHA) in order to improve the design of the small-craft harbour at San Sebastian in the North of Spain (fig.l). San Sebastian is one of the most well-known and beautiful tourist cities in Europe and for that reason aesthetic as well as environmental aspects of construction had to be taken into account.
