| Abstract: | Wen et al's method developed to obtain wind-wave frequency spectrum in deep water was used to derive the spectrum in finite
depth water. The spectrumS(ω) (ω being angular frequency) when normalized with the zeroth momentm
0 and peak frequency {ie97-1}, contains in addition to the peakness factor {ie97-2} a depth parameter η=(2πm
o)1/2/d (d being water depth), so the spectrum behavior can be studied for different wave growth stages and water depths.
