(b) For the second condition where T^nax ~ ^^ seconds, 

 the maximum runup would occur for the lowest dg/H^ value.

Table 2 may be constructed for dg = 10 feet, T = 13 seconds, 

 gT^ = 5,441.8 feet, and using Figures 8 to 11. Table 2 shows 

 that, in this case, not only is runup higher for the longer 

 wave period than in Table 1, but the maximum runup occurs at a 

 lower dg/H|^ value for the maximum deepwater wave.
