Any attempt to model the frequency-and direction-dependent ocean wave spectrum F(f, θ)is a formidable task. The only more or less unified theory (Hasselmann, 1967) has not been reduced to a practical form. The approach taken in this study is to combine individual, existing theories to produce results that are compatible with our present understanding of the evolving wind wave spectrum. In this chapter we discuss a discrete spectral model that uses an adaptation of the method of characteristics to propagate energy. The numerical method was discussed originally by Barnett et al. (1969).
