A Novel Method for Estimating Wave Energy Converter Performance in Variable Bathymetry Regions and Applications
A numerical model is presented for the estimation of Wave Energy Converter (WEC) performance in variable bathymetry regions, taking into account the interaction of the floating units with the bottom topography. The proposed method is based on a coupled-mode model for the propagation of the water wav...
