This study aims to develop a new wave equation model by modifying the Fully-nonlinear and strongly-DispersiveSurfacewave(FDS)equations.Themodificationwasperformedbyapplyinga new expansion in a series of the vertical coordinate, zμ, to the velocity potential while a simple expansion in a series of z was applied to the FDS equations. Verification of the model was conductedby comparing withthe theoreticalsolutions ofsurfacesolitarywaves.Weappliedthe modifiedFDSequationstowave fieldsoverabumpunderconditionswithandwithoutcurrents, which agreed very well with the time series of wave heights and velocity obtained from laboratory experiments. The dispersion relationship computed using the normali...
