+8.0 ft, and +9.5 ft. Since no significant overtopping occurred at +6.0 ft 

 swl, the minimum water level was raised to +7.0 ft NGVD. A data plot of Q 

 versus F' showing results of the Phase I seawall tests is presented in Fig- 

 ure 9. Detailed test data are tabulated in Appendix A, Table Al . The data 

 presented in Figure 9 show a definite trend which can be defined by the fol- 

 lowing general equation: 



Q = Q exp (C F')

where 



Q = overtopping rate, cfs/ft 

 Q = regression coefficient, cfs/ft 

 C = dimensionless regression coefficient 

 F' = dimensionless relative freeboard parameter
