We examined the validity and the effectiveness of the DIA on the basis of the accuracy of the computations of the nonlinear energy transfer for various directional spectra. Then, we proposed new methods, an extended DIA (EDIA) and a modified DIA (MDIA). The optimum parameters included in EDIA and MDIA were properly adjusted by minimizing the errors between the exact values and their approximate values for various directional spectra. The efficiency and accuracy of the EDIA and the MDIA were examined for various directional spectra and computational conditions.
