RT Journal Article T1 Shape optimization of geotextile tubes for sandy beach protection A1 Isebe, Damien A1 Azerad, Pascal A1 Bouchette, Frederic A1 Ivorra, Benjamín Pierre Paul A1 Mohammadi, Bijan AB This paper describes how to tackle new challenging coastal engineering problems related to beach erosion with a shape optimization approach. The method modifies the shape of the sea bottom in order to reduce beach erosion effects. Global optimization is shown to be necessary as the related functionals have several local minima. We describe the physical model used, the proposed protection devices against beach erosion and real case applications. PB John Wiley & Sons Ltd.
