It is found that there are similarities in terms of spectral integral among the wind input source terms given by Jeffreys, Sverdrup and Munk, and Plant and among the wave breaking dissipation source terms given by Tsikunov,Hasselmann and Philips,although the original forms and the physical considerations of these source terms are significantly different.
The LAGFD-WAM numerical wave model is a third generation numerical wave model. In this model, the wave direction spectrum in wave number space is simulated by solving the wavenumber spectrum balance equation and taking into consideration the wind input, wave breaking dissipation, bottom friction dissipation, wave-wave interaction and wave-current interaction source functions, and the wave height, wave period and mean wave direction are then obtained.
WAM-type model terms are used to estimate energy input to waves by wind and removed by wave-breaking dissipation.

Based on the result of breaking wave statistics, this study derives a new theoretical breaking dissipation source functionand its more applicable formula,in which d1 = 1.32×10-4, d2 = 2.61.This expression overcomes the flaw of other present third-generation numerical wave models, for it gives lower dissipation value for the high sea state condition.Application of the above source function improves the LAGFD-WAM numerical wave model. Results show that, in high wind condition, the mode...
The existing wind wave growth formulas (WWGFs) in the form of power function, which were presented on the basis of measurements, are analyzed. It is shown that these WWGFs after eliminating the fetch are uniformly consistent with the 3/2 power law, though there are considerable discrepancy among them.It is found that there are similarities in terms of spectral integral among the wind input source terms given by Jeffreys, Sverdrup and Munk, and Plant and among the wave breaking dissipation source...
