similar for both series consisting of different sequences of storms of similar cumulative 

 wave action. The damage data showed partial healing during damage progression, 

 where eroded pockets from displaced stones were filled in by minor shifting of 

 surrounding stones. 



The probability density functions of damage, eroded depth, and cover depth 

 were analyzed in Chapter 5. For each series, at each point in time, the probability 

 density functions of normalized values, given by Equation 5.6 as 



= ; E = ; C = 



are shown to have ranges given by Equation 5. 10 as 



-2.7<5'<3 ; -2.7<£'<2.7 ; -2.7 < C*< 2.8 



All normalized variables are in the range from -3 to 3. It is shown that series with lower 

 overall damage levels had negatively skewed distributions with fewer points in the 

 negative tail in the range -3 < 5* < -2 due to the fact that there were few measurements 

 at very low damage in the range .^= - 1. 



Equation 6.1 was obtained through statistical analysis of the profile data to 

 describe the alongshore variability of damage as
