Abstract: In this study, a genetic algorithm is developed which incorporates a hydrodynamic numerical model to achieve an efficient design strategy for the planform of breakwaters in order to optimize the breakwater geometry by minimizing wave heights entering the harbor. The optimization approach of the genetic algorithm finds the best possible solution among different geometries for the breakwater by minimizing the wave height in the harbor, while applying the economic considerations through the constraints of the length of the breakwater. An optimized geometry is reached by optimizing the length and angles of a broken line for the breakwater alignment. The simple crossover (single-point) method is compared to the convex crossover method, which allows definition of convex search zones. By changing the range of variables of the problem, different breakwater shapes resulted from the optimization operations and their effects on the results are studied
