Figure 6. 1 . Prediction of damage variability, characterized by the standard deviation, as 

 a function of mean damage for Series A', B', and C 



6.2 Eroded Profile Prediction 



It is useful to express the normalized eroded depth .E'and the variability of 

 eroded depth, o^, as a function of mean damage also. The measured values of ^'and E± 

 0£ were shown as a function of cumulative number of waves for Series A ' in Figure 

 5.13. The trends for Series B' and C were shown to be similar in Figures 5.18 and 5.19. 

 Figures 6.2 and 6.3 show ^'and o^ as a function of .yfor all data points of the three 

 series. These figures indicate the following empirical relationships
