Abstract
    In the present work the application of an advanced hydromorphological mathematical model for the design of innovative submerged structures for coastal protection, is presented. Non linear wave transformation in the surf and swash zone is computed by a non-linear breaking wave model based on the higher order Boussinesq equations for breaking and non breaking waves. The new Camenen and Larson (2007) transport rate formula involving unsteady aspects of the sand transport phenomenon is adopted for estimating the sheet flow sediment transport rates as well as the bed load and suspended load over ripples. Suspended sediment transport rate estimation is based on an exponential profile of sediment concentration for the steady equilibrium according to Camenen and Larson (2007, 2008). The methodology is applied for the simulation of sediment transport and morphology evolution in coastal regions where innovative submerged structures/vegetation for coastal protection have been constructed. These structures and vegetation reduce the incident wave energy and consequently the wave erosive action.
