A parameter wave hindcast model for wind generated waves in short fetch sea was developed through the investigation of the wind stress and wave growth formulas
using the data obtained in Osaka Bay. Accuracy of the numerical results of the wave hindcast model was also studied by the comparison with the results of other convensional wave hindcast model and the measured data.
　The main conclusions are as follows: Data obtained in Osaka Bay less than 15m/s of 10m high wind speed satisfied similarity laws with good accuracy independing
on wind stress formulas. The significant wave hindcast model and SMB method can not be got accurate results when wind speed is more than 20m/s. Spectrum model also cannot obtain good results independing on wind speed renge because wave spectra in short fetch sea have a tendance to overshoot against fully developed stectrum. Even if the wind is more than 20m/s,similarity laws describing shear velocity with the presented wind stress formula are suitable and the parameter wave hindcat model computes accurate results.
