| Abstract: | Combining the 3/2 power law proposed by Toba with the significant wave energy balance equation for wind waves, wave growth
in deep water for short fetch is investigated. It is found that the variations of wave height and period with fetch have the
form of power function with fractional exponents 3/8 and 1/4 respectively. Using these exponents in the power functions and
through data fitting, the concise wind wave growth relations for short fetch are obtained. |
