Column 7 is the deepwater significant wave height H^ and is 

 obtained from Equation 3-40; 



H^ = 0.0555 U^ y/F^ = 5.08 y/f^ , where U^ = 91.6 knots 



and F is obtained from Column 6. 



Column 8 is the deepwater significant wave period T^ and is 

 obtained from Equation 3-36: 



T = 2.13 VH where H^ is obtained from Column 7. 



Column 9 is T^/dy, or Column 8 squared over Column 5. 



Column 10 is the shoaling coefficient (H/H' ) or K corresponding 

 to the value of T^/dy, Column 9, and is obtained from Table 3-3 Kg 

 versus T^/d. 



Column 11 is the friction loss parameter and is equal to 



frH K AX 0.01 H K, (5) (6,080) 304 H K 



M' M' M' 



where f^ is assumed as 0.01, AX = 5(6,080) = 30,400 ft., dj, is the 

 average water depth of the increment AX. 



Column 12 is the friction factor K^ and is obtained from Figure 

 3-35 where Ky- is a function of T^/dy (Column 9) and 



(fH K AX 



^ ,- , = A (Column 11). 



Column 13 is the equivalent deepwater wave height H^ and is 

 obtained from H' = H K (the product of Columns 7 and 12) . 



Column 14 is the equivalent effective fetch length for H^ and is 

 obtained from Equation 3-40 



F ' =

where U^j = 91.6 knots (moving hurricane). 



Column 15 is obtained by using Equation 3-36 T^ = 2.13 vH^. 



Column 16 is (T')^/d„, where d„ is the water depth at shoreward 

 end of section AX.
