(Heimbaugh et al. 1988) over a range of sea state conditions to measure wave- 

 induced overtopping. Parameters which required evaluation and were incorpo- 

 rated into the model test were the design wave conditions, the design storm 

 surge levels, the seawall geometry, and the beach profile. 



7. Model tests were run using spectral waves on two different seawall 

 cross sections or templates. A Phase I template resulted in a peak over- 

 topping rate in excess of the value predicted of 0.125 cfs/ft of seawall in a 

 general design memorandum (NAO 1983) . Selected modifications were made to the 

 wall cross section to reduce these quantities, and the Phase II wall did lower 

 the overtopping rates (Heimbaugh et al. 1988).
