Selected Design Conditions 



The follo\Nmg design conditions are 

 assumed for the illustrative purposes o-f this 

 problem. 



Water Levels (Ml\i\j datum) 



1. Storm surge (less astronomical tide) 



Use 11.0 ft 



2. Astronomical tide (use rvater level 



exceeded 1% of time.) 



Use 5.0 ft 



3. Nave setup (assumed negligible 



since structure is in relat/veiu 

 deep water and not at beach) 



Wove Conditions on boq Side of Island 



I. Use conditions witti loo gr recurrence 

 interval. 



Use Hi = &9 ft 



Is - G.6 sec. 



Nave Conditions on Ocean side of Island 



I. Hurricane 3 waves 



y^= 16.7 ft; T^ = %1 sec. 



Z. From hind cast statistics (wave height 

 exceeded 1% of time) 



/% = as ft 



Use Hr = fd.O ft 



8-64
