Abstract

The present paper presents results from hydraulic model testing of the outer part of the new western breakwater for the Port of Hanstholm, Denmark. The design waves in Hanstholm are depth limited and breaking on a relatively steep, complex and dynamic foreshore. This causes the waves to shoal and focus on certain sections of the breakwater. The chosen armour layer design was high density Cubipods® in a single layer as both front and rear side armour. On the front side an underlayer of quite large rocks was used in order to secure stability during construction. Thus, the conditions deviate in several ways from previous projects where Cubipods® have been applied, i.e. high density concrete, coarser underlayer, breaking and depth limited waves on a complex bathymetry. For thesereasons the design was tested and optimized in three-dimensional hydraulic model tests as presented in the present paper.
