A new computational scheme for calculating the nonlinear energy transfer in finite-depth gravity wave spectra has been developed by extending the methods established by Masuda (1980) and Komatsu et al. (1993). In this paper, the formulations for the numerical computation of the nonlinear energy transfer for finite-depth water waves are shown with the analytical solution around the singular point of the Boltzmann integral. The numerical computational procedure for the proposed method is described in detail. Some results of numerical examinations for finite water depth, assuming two different types of directional spectra, are shown with discussions on the validity of the proposed method.
