The mild-slope equation has been used for calculation of the surface gravity water wave transformation. Recently, its extendedversions w ere introduced, which is capable of modeling wave transformation on rapi dly varying topography. These equations were derived by integrating the Laplace equation vertically. Here, we develop a new finite element model to solve the Laplace equation directly while keeping the sam e computational efficiency as the mild-slope equation. This model as sumes the vertical variation of the wave potential as a cosine hyperboli c function as done in the derivation of the mild-slope equation, and the Galerkin method is used to get a finite element solution. The computational domain is discretized with an infinite element. The applicability of the developed model is verified through exam ple analyses of two-dimensional wave reflection and transmission. © 2015 International Information Institute.
