This equation, along with Equation 5.10, can be used to predict the range of damage for 

 a given level of mean damage. These relations indicated that alongshore damage 

 variability was greater than previously suspected and could be significant in a life-cycle 

 cost analysis. 



The damaged profile shape, as characterized by the mean eroded depth E 

 and mean cover depth C, was shown to be well described in terms of the mean damage 

 by Equations 6.2 and 6.5 



E = 0.46^/5 



C = Cq - 0.15 



where Q is the mean cover depth when 5=0. The mean eroded length was shown to 

 be described in terms of the mean damage by Equation 6.4 as 



I = 4.4v^ 



The variability of eroded depth and cover depth was shown to be described by 

 Equations 6.3 and 6.6, respectively, as 



o. = 0.26 - 0.00007(5-7.8)^ 



0^ = 0^ + 0.098 - 0.002(5-7)2
