wave analysis, but because there are several ways to compute each with the 

 data at hand, they are defined specifically here. The parameter set consists of 

 characteristic wave height H^, characteristic wave period T , characteristic 

 wave direction 8 , representative directional spread of wave energy 58 p , and 

 water depth d . 



Characteristic wave height H^ is defined, as usual, as four times the 

 standard deviation of sea surface displacement, based on variances contained 

 in the frequency spectrum S(f) between the low- and high-frequency cutoffs. 

 In this analysis, S[f) is computed as the average of the surface-corrected 

 frequency spectra from each of the nine gauges in the linear array. This does 

 not increase degrees of freedom (because all gauges are measuring the same
