heal.abstract	A new coupled-mode model is presented for the wave-current-seabed interaction problem, with application towave scattering by steady currents over three-dimensional bottom topography.The vertical structure of the wave field is modelled by a series of local vertical modes, consisting of the propagating and all evanescent modes, plus an additional term accounting for the bottom boundary condition on the sloping bottom. If only the propagating mode is retained in the vertical expansion of the wave potential, and after additional simplifications, the above coupled-mode system reduces to the one-equation model earlier derived and studied by Kirby (1984). The present system is numerically solved by means of a parallel implementation, permitting direct numerical solution for realistic domains corresponding to areas with size of the order of several kilometres, and facilitating the transformation of wave energy spectra in the presence of variable bottom topography and currents. © 2008 Taylor & Francis Group, London.	en
