• Wave absorbing quay-wall
• Partial wave chamber
• Wave reduction
• Experimental investigation

In this study, a new type of wave absorbing quay-wall with a partial wave chamber is introduced. In addition to the basic design containing a wave chamber with an impermeable back wall, there are several alternative absorbing systems that use rock within the core of the wave chamber. These systems have been experimentally investigated to determine whether they further reduce wave heights in front of the wall. Then, they have been compared to a conventional quay-wall with a solid front wall. Their improved performance indicates that this is an effective new scheme for a wave absorbing quay-wall. This new scheme, which consists of a partial wave chamber containing a rock-armored slope, was experimentally compared with a conventional quay-wall with a solid front wall in the 3D physical model of the port of Piraeus, Greece. Results show that wave heights in front of the new absorbing quay-wall can be reduced by 20-30%. The experimental results were verified in the field, where the extension of the quay-wall of the port of Piraeus was finally constructed with the new and effective wave absorbing system.
