APPENDIX B 



GRANULOMETRIC DATA 



Appendix B contains the results of Rapid Sand Analyzer (RSA) size analyses of selected 

 sediment samples from the study area. 



The samples are identified by core number, CERC identification and sample interval 

 below top of the core. These samples are plotted by number in Figure 2. 



Data include mean (X) size values (phi and millimeter) and standard deviation or sorting 

 coefficient (a) from direct RSA analyses. 



CERC has determined empirical relations for converting RSA means and standard 

 deviation to sieve analyses equivalents, from 99 beach samples obtained in New Jersey, 

 Michigan, and California. The relationships, developed from RSA and sieve analyses at a 

 0.25 phi interval, are: 



means: X^ M = 1.0735 Xqrsa + 01876 

 Sieve millimeter values were derived by means of a conversion table. 



RSA standard deviation values were converted to sieve sorting equivalents by the 

 formula: 



standard deviation: cu sieve = 1.4535 a^ RSA — 0.146
