Abstract. Wind waves, which are one of the most important phenomena in the marine environment, are generally progressive in nature and can move far distances out of their area of formation. Thus, an understanding of wave hydrodynamics and their eects is important for engineers in the design and construction of marine structures and coastal management. Signicant insights may be gained from numerical and laboratory studies. Often the waves simulated in numerical and physical models do not have the full characteristics of real sea waves. It is then necessary to present a reliable method of wave simulation for numerical and laboratory wave umes. In this paper, the results of numerically simulated water waves, using digital lters, are presented. A model has been developed to simulate a water wave prole from dierent target spectra using WNDF methods. The results showed that the WNDF method involves good stochastic wave characteristics if a suitable spectrum is used as target. The results have implications for the numerical or laboratory estimation of wave forces on model oshore or coastal structures.
