OPTIMAL PLANFORM DESIGN OF BREAKWATERS FOR MINIMAL WAVE IMPACT

Shape optimization belongs to the category of inverse problems, where numerical simulations or experimental approaches are used not only to find the solution of a given system, but also todiscover the set of parameters of the system producing a suitable solution [1], [2]. Groins, breakwaters, jetties and many other structures are used to attenuate water waves or to control sediment flows. Their shapes are usually determined using simple hydrodynamical assumptions,structural strength laws and empirical considerations. However shape optimization techniqueshave been rarely used in coastal engineering [3]. In this paper a shape optimization algorithm has been developed, which with the use of a wave propagating model, an optimum planform design for structures is obtained.
