Hindcost waye statistics ore available for 

 several U.S. East Coasi locations in Reference 7. 

 linear ihterpolotion between the Nev^York and. 

 Chesapeake Bag sta tions was used to determine statistics 

 for the Delaware bay region (see next page). Since 

 the data are given for deep water, a refraction 

 analysis is required to transform the statistics 

 to the is/and site. 



Idealized Refraction Anal g sis 



/or purposes of this problem, refraction by 

 straight parallel bottom contours will be 

 assumed.
