Figure 5.17. Mean damage versus mean maximum eroded length for Series A' 



Figures 5.18 through 5.23 show that the profile development characteristics 

 for Series B' and C are similar to those of Series A ' discussed above. Figures 5.24 

 through 5.27 show means of the three profile parameters versus mean damage for Series 

 B' and C. It is clear that profile development is related to mean damage. This will be 

 investigated in the following chapter.
