Figure 5.10 shows the number of waves A^„ versus the measured average 

 damage SfoT Series A' for A'p = 16. Here, the cumulative number of waves N,^ is 

 obtained using the mean wave period T„ from Table 4.4 and duration of Waves 1-6 

 listed in Table Bl in Appendix B. Also shown are the alongshore variability of damage 

 as one standard deviation above and below S. For Series A', waves were run at the 

 initial depth until the structure appeared to stabilize, which occurred after approximately 

 22,000 waves. At that point, the water depth was raised. As noted in Table 4.4, the 

 stability number ranged from 1.6 to 2.2 for the shallower depth and from 1.7 to 2.5 for 

 the deeper depth. In this figure, the significant wave heights H^ and associated stability 

 numbers A^^ are listed across the top of the figure, while the water depths at the toe are 

 listed across the bottom of the figure.
