Relative runup is determined from the appropriate set of curves; for 

 a structure located on a 1 on 10 beach with dg/H^ = 1.0, use Figure 

 21. The value of £/L must then be determined. 



I = (15 - 3) (10) = 120 meters (393.7 feet). 



Next, determine the wavelength in water depth of 15.0 meters (the
