PURPOSE: To dissipate waves without scouring the bottom of the sea by erecting a number of long-size wave dissipating bodies on an anchor base or the bottom of the sea along the longitudinal direction of an elastic material which is deflected when receiving waves.
CONSTITUTION: A wave dissipating portion 2 in the form of a long-size plate made of an elastic material such as rubber is erected integrally with the upper side of the footing 5 of a base 1 to form a wave dissipating body 3. The elasticity of the wave dissipating body 3 is varied by embedding a reinforcing material such as fiber or a wire gauze in the back and/or front side of the wave dissipating portion 2, or by stretching the reinforcing material on one or both sides of the wave dissipating portion 2. A number of wave dissipating bodies 3 are erected on an anchor base or the bottom of the sea.
