Abstract
We point out one problem of the grid advection schemes when used in wa ve models in coastal areas. The deficiency of the schemes is investiga ted by means of the 'third' generation WAM wave model, in which the wa ve energy is advected by a first order upwind scheme. Two similar, alt ernative modifications of this scheme are analyzed, the second of whic h is shown to solve most of the problems encountered with advection al ong the co-ordinate axes.
