Abstract
The implementation and first validation of a hybridization technique between a NLSWE model and a meshless fully Navier-Stokes equation-based model are presented. The scope is to overcome the limitations of each numerical model (different computational costs and capabilities) and to obtain a unique tool capable to represent the whole phenomena of wave propagation, transformation and interaction with coastal structures. The hybrid model has been validated with physical model data of monochromatic waves running over a sandy beach and has provided notably improved predictions of water surface elevation and orbital velocities. Preliminary results for random waves are also reported.
