| Abstract |
The work presented in this article aims to make the TELEMAC suite capable of simulating cross-shore sediment transport through the implementation of the different cross-shore processes in the GAIA and TOMAWAC modules. Surface roller energy produced in the breaking wave front, wave breaking turbulence, the return current that counterbalances the so-called Stokes drift appearing close to the water surface and wave non-linearities developing in the surf zone are the processes that are introduced in the code. The new developments are evaluated by means of a 2D-morphodynamic model for the central part of the Belgian coast, which is validated against field measurements under realistic forcing conditions. The results show that the implementation of the cross-shore processes is an added value in the modelling of the near- and onshore bed evolution. |
