Overtopping rate is presented as a function of incident wave height and wave 

 period for the +4-ft swl in Figure 15. These data show that both wave periods 

 give similar results: wave heights of 4 ft and above produce major overtop- 

 ping (rates in excess of 0.5 cfs/ft), and maximum overtopping rates of approxi- 

 mately 3 cfs/ft can be expected for the largest waves that reach the structure.
