Abstract. In this paper, shape optimization tools are applied to coastal en-
gineering. A barred beach protection study is described, using a new type of
water wave attenuator device, namely geotextile tube, to reduce the mobiliza-
tion of sediments. A global optimization algorithm, able to pursue beyond
local minima, is used to search for the optimum properties of the geotextile
tube.The optimal configuration is then post-validated for generated currents.
1. Introduction. Despite beach protection becomes a major problem, shape opti-
