Present invention provides a resilient wave reducing structure which reduces waves propagating on liquid surface from propagating over the reducing structure. The present invention also provides a method of constructing the wave reducing structure. The wave reducing structure of the present invention may be used to form a calm water surface region for harbours, for areas where construction work is being done or for areas where marine sports are to be performed etc. The wave reducing structure of the present invention is distinguished from conventional breakwaters by being smaller in width and lower in height. They are also distiguished from conventional ones by being constructable and removable easily, quickly and cost-­savingly. The method of constructing the wave reducing structures provides a practical method which enables to make the maximum use of the above-mensioned characteristics of the structure in constructing them.
The resilient wave reducing structure of the present invention realizes the above mensioned characteristics by comprising at least one energy absorbing means having a resilient body constructed on a bottom of the liquid bounding the region where waves have to be reduced. The resilient wave reducing structure reduces the amplitude of waves passing over it by consuming the wave energy while it deformes according to the pressure distribution change caused by the waves and by radiating its kinetic energy into the liquid and the ground surrounding it. Because of the above-mensioned energy consumption mechanism, the resilient wave reducing structure is more effective than conventional submerged breakwaters in reducing waves from propagating over it.
Furtheremore, because the wave reducing structure is resilient and deeply submerged under water, it does not hinder ships from passing over it. Therefore, it becomes possible to create a calm region on a liquid surface without hindering a navigation of ships and without creating a danger of wrecking the ships.
