The layout of breakwaters, shape and location, is usually designed by assessing several concepts based on the designer engineer experience. The design has not been addressed as a hydrodynamic analysis problem to obtain a solution. This may be due to the difficulty of the hydrodynamic analysis and evaluation of such marine structures regarding their arbitrarily shapes [1]. The purpose of this study is to a achieve an efficient design strategy for the planform of the breakwaters , as such by minimizing the wave heights, comfort and safety are achieved in the coastal zones and harbor access canals. To aim this, a genetic algorithm is developed which incorporates with the REF/DIF numerical model to optimize the geometry and location of breakwaters where the wave height is minimized.
