=== Wave absorbing caisson ===
A similar but more sophisticated concept is a wave-absorbing caisson, including various types of perforation in the front wall.

Such structures have been used successfully in the offshore oil-industry, but also on coastal projects requiring rather low-crested structures (e.g. on an urban promenade where the sea view is an important aspect, as seen in [[Corniche_Beirut|Beirut]] and [[Land_reclamation_in_Monaco|Monaco]]). In the latter, a project is presently ongoing at the [[Le_Portier|Anse du Portier]] including 18 wave-absorbing {{cvt|27|m}} high caissons.
