Figure 4-7. Summary of mean water level and selected wave parameters 

 across inner surf zone and swash zone for Run A0509A 



frequency component dominates. The low-frequency component increases in 

 magnitude to a maximum value at the initial shoreline and exhibits a spatial 

 variation similar to that of the mean wave setup in Figure 4-7a. The high- 

 frequency wave component, in contrast, decays continually from the surf zone 

 to the runup limit.
