the physical situation of Revere Beach violates the one-dimensional assump- 
tions used in developing the model, reasonable results were obtained. Further 
verification tests should be performed in the future when additional data 
become available. For the present purpose, the model has been shown to be 
adequate for estimating berm recession for the Sea Bright to Ocean Township 
area. The following section will focus on application of the model to deter- 
mine the amount of recession in front of the project seawall as a result of a 
stochastic application of both hurricanes and northeasters of known frequency 
of occurrence.

152. The need for an effective beach renourishment program was recog- 
nized following the occurrence of the November 1953 storm which caused wide- 
spread damage to the project beach area. Three alternate berm width plans 
(CE 1984), based on post-storm recommendations, were selected for evaluation: 
a. A historical maximum width of 100 ft corresponding to the 
average dune recession measured during the November 1953 
storm. The design profile for the 100-ft width is shown in 
Figure 25. 
b. A minimum width of 30 ft recommended by the Beach Erosion 
Board (BEB) in 1959. 
ec. An intermediate design of 50 ft (also recommended by the BEB) 
as a realistic compromise of the two extremes. 
153. The beach erosion model was selected as a means of systematically 
evaluating the effectiveness of a coastal system to withstand a variety of 
storm events. The methodology used to evaluate the proposed berm width alter- 
natives makes extensive use of the stage-frequency analysis described in 
Part VI of this report. In that chapter, details on the generation of hurri- 
canes and northeasters are presented. The generated storms are used to 
develop stage-frequency curves corresponding to both hurricanes and north- 
easters. Both types of storm events were analyzed because of basic differ- 
ences in the characteristics of the two; hurricanes tend to have very high 
surge levels which are relatively short in duration, whereas northeasters are 
lower in surge level but substantially longer in duration. Each generated 
hurricane and northeaster is composed of a randomly selected storm surge of 
known duration superimposed on a randomly selected tidal series. The
