(c) The percentage of the wave height above the SWL may be determined 

 from Figure 2-13. Entering the figure with L^H/d^ = 190, the 

 value of (y^ - d)/H is found to be 0.833 or 83.3 percent. 

 Therefore , 



Yc 



= 0.833 H + d. 



y^ = 0.833(2.5) + 10 = 2.083 + 10 = 12.083 feet . 

 Also from Figure 2-13, 



(y, - d) 



H 



thus 



+ 1 = 0.833 



y^ 



= (0.833- 1) (2.5) + 10 = 9.583 ft. 



(d) The dimensionless wave profile is given on Figure 2-9 and is 

 approximately the one drawn for k^ = i - 10"^. The results 

 obtained in (c) above can also be checked by using Figure 2-9. 

 For the wave profile obtained with k^ = 1 - 10"'*, it is seen that 

 the SWL is approximately 0.17 H above the wave trough or 0.83 H 

 below the wave crest. 



The results for the wave celerity determined under (b) above 

 can now be checked with the aid of Figure 2-15. Calculate 



0.261 . 



y^ 



it is found that

Therefore
