Estimation of significant wave period from wave spectrum

摘要: Abstract Although the significant wave period is one of key parameters in design coastal structures, it not calculated by spectral model because obtained zero-crossing analysis. The present paper examines several formulas that relate to such as peak period, mean and peakedness parameter. are derived based on measurements two locations Japan/East Sea (JES). then compared with measured periods other JES. It shown formula using T m − 1,0 , most accurate. This further used a model, from which measurement. Additionally, relationship between height hindcasting, probable can be determined for specific height. A comparison measurement shows relatively inaccurate where southerly swell waves significant, accurately taken into account numerical model.
