ESTIMATION OF WAVE GROUPS PARAMETER FROM WAVE CLIMATE STATISTICS

Satoshi Nakamura

Abstract


Field measurement of sea surface elevation for analysis of wave groups have been carried out at the 4 wave observation points around Japan about for 6 months. As the result of analysis of coefficient variation of wave group parameter, that a record length of wave data needs more than 60 minutes for the reliable statistics of wave groups. Using the wave record of the enough length for wave groups analysis, the empirical relationship between wave group statistics and wave climate statistics is estimated.
