Table 5 shows the characteristic relationship that the largest 

 runup, R, occurs for the lowest d s /H^ value when H^/gT 2 and 

 d s are constant; however, the largest relative runup has lower 

 dimensional runup. Furthermore, Table 5 does not indicate the 

 maximum runup to be expected on this structure for the given con- 

 ditions. Table 3 shows the maximum to be «7.05 meters for a 

 maximum period of 7.0 seconds.

Thus, care should be exercised in determining runup for a particular 

 structure. The results of the three parts of this problem are 

 summarized in Table 6. Scale-effect corrections applicable to this 

 example problem are discussed in Section VI.
