Figure 16. Distribution of directional spread 



parameter derived from integrated 



direction spectra 



193. This result is supported by the distribution of spectrally 

 weighted directional spread estimates shovm in Figure 17. Here, the range is 

 similar, being from about 15 to 50 deg. Most probable values are in the range 

 from about 34 to 42 deg. These numbers are all slightly less than
