NUMERICAL VALIDATION OF WAVE PROPAGATION, TRANSFORMATION AND DISSIPATION TOWARDS A HARBOUR FACILITY: A NEW BECHMARK CASE

Abstract

A new set of experimental data is used in the numerical validation (2DH) of waves propagating towards a scaled harbour facility. The Laredo marina-harbour located at the North coast of Cantabria (Spain), which has lately improved by the extension of its main breakwater, was modelled in the 28 m long and 8.6 m wide directional wave basin of the Environmental Hydraulic Institute, at the University of Cantabria. For two months, different 3D tests were simulated for this harbour configuration, starting with the detailed construction of the real bathymetry contour data, and followed by the construction of the 450 m (trunk and head), of a curved rubble-mound, 1:2 slope breakwater, capped with a variable height L-shaped crownwall and the armour layer is composed of 60 ton (trunk) and 70 ton (roundhead) cubic units.
