F. 6.2. Volume Analysis South of Canaveral Harbor 



The pre-Harbor, October 1951 survey was completed by the USACE just prior to the cut 

 through the barrier island for the first 10,500 ft of shore south of the Harbor. The October 1951 

 survey was compared with the May 1954, December 1958, March 1965 to January 1966, 

 May 1975, March and December 1979, August 1985 to May 1986, January 1994, January and 

 May 1996, and May 1997 surveys to determine volume changes. These volume changes were 

 computed for the beach profile from the landward limit of the survey data seaward to the -17-ft 

 contour of the October 1951 survey and are listed in Table F-12. Similarly, volume changes 

 were computed for the beach profile from the landward limit of the survey data seaward to the 

 October 1951 MHWL (Table F-13). Some of the available survey data (see Tables F-4, F-5 and 

 F-6) were not included in the volume computations (such as the October 1956 and the January, 

 June, and October 1995 surveys), as there were sufficient surveys for comparison purposes for 

 these time frames. Other surveys (refer to Tables F-3 and F-7) were excluded from the volume 

 analysis because of their limited lineal extent. 



The May 1954 survey repeated and expanded the October 1951 survey. The May 1954 

 coverage extends from 210+00N to 343+98S. The Harbor impact was fairly limited in 1954 as 

 evidenced by volume changes to the -17-ft contour for 10,500 ft of shore north and south of the 

 Harbor of +286,800 and -148,600 cy, respectively (refer to Tables F-9 and F-12). Therefore, the 

 May 1954 survey is better suited as the baseline for pre-project conditions since its lineal extent 

 is twice as great north of the Harbor and three times longer south of the Harbor as compared with 

 the October 1951 survey and is more suitable as a pre-Harbor survey. 



The May 1954 survey was compared with the December 1958, March 1965 to January 1966, 

 May 1975, March and December 1979, August 1985 to May 1986, January 1994, January and 

 May 1996, and May 1997 surveys for the shore 34,398 ft (6.5 miles) south of the Harbor. 

 Volume changes were computed for the beach profile from the landward limit of the survey data 

 seaward to the -17-ft contour of the May 1954 survey, (Table F-14). Similarly, volume changes 

 were computed from the landward limit of the survey data seaward to the May 1954 MHWL and 

 the results displayed in Table F-15 and shown on Plates F-l through F-8. Since the May 1975, 

 March and December 1979, January and May 1996, and May 1997 surveys only extend to 2.8 

 miles south of the Harbor, they could not be used to compute volumes for 6.5 miles of shore.
