The 3D wave basin is a 30m x 30m shallow tank of water for modelling the action of waves on coastal structures. A wave generator makes monotonic or random wave sequences which then wash against model structures, the disruption of the models is used to estimate the damage to equivalent prototype designs.

A general view of wave basin building.	The wave generator is on the left side with some guides to direct the waves onto the test area.
The wave generator is a computer controlled, hydraulically actuated wedge which generates either monotonic or random wave sequences.	Another view of a model breakwater.

These are some models of the construction components for breakwaters, they are cast in epoxy resin loaded with sand to model the density of prototype materials.
