IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Numerical analysis of obliqueness in wave-induced crown wall loads
Author : PABLO HIGUERA(1), JAVIER L. LARA(2) & INIGO J. LOSADA(2)
ABSTRACT
Numerical modelling plays an increasingly important role in the design of coastal protection structures. This tool can
provide a detailed characterization of the hydrodynamics around any structure, avoiding scale effects and, therefore,
reducing the uncertainty and high cost associated to this kind of calculations, which have traditionally been addressed by
physical modelling.
In this paper the IHFOAM numerical model is applied to simulate the interaction of a sea state with a real structure, the
Port of Laredo (Spain) rubble mound breakwater, in three-dimensions and at prototype scale. The exterior breakwater of
this port is curved and includes three different crown wall sections, thus enabling the analysis of multiple wave incidence
angles all at once.
The analysis of the numerical data yields the stability regime of the real structure, without scale effects. The results
indicate that the breakwater presents an adequate design, as the safety coefficients against sliding and overturning are
above the minimum required. Moreover, no overtopping is detected because the recurved wall deflects the splashes in the
seaward direction.
