Abstract
The knowledge and understanding of nearshore processes are essential for several applications, namely the design of coastal protection and harbor sheltering structures, the evaluation of sediment transport and coastal erosion or the assessment of wave power available at a certain spot. The combined effect of waves and currents in free surface flows has been the subject of several studies due to its importance on the hydrodynamics of coastal waters. In the past decade a number of theories were developed to get a complete description of the three dimensional effects of this phenomena. To analyze wave-current interaction, the recent formulation presented by Ardhuin et al. (2008) was used in the development of a coupled system between the three dimensional hydrodynamic model TELEMAC3D and the spectral wave model TOMAWAC. Ardhuin et al. (2008) approach is based on the generalized Lagrangean mean (GLM) theory and they were able to get expressions for the wave forcing terms needed to close the GLM equations. Through a vertical change of coordinate they obtained the so called glm2z-RANS equations. Numerical results are compared with an adiabatic shoaling waves test and after with experimental data from the Large Scale Sediment Transport Facility (LSTF) at the US Army Engineer Research and Development Centers Coastal and Hydraulics Laboratory, Vicksburg, USA.
