APPENDIX B 



LABORATORY STUDIES OF PROFILE DEVELOPMENT 



The data base for the comparison in Figure 3 is 47 published profiles 

 from 7 laboratory studies with constant wave action on an initially plane 

 slope of fine sand. Table B-1 lists these profiles from seven references. 

 Column 1 gives the original test identification. Column 2 lists the slope 

 of the initial plane beach; values in parentheses indicate the slope was 

 truncated by a steeper offshore slope. Column 3 gives the sand diameter, 

 and column 4 gives the time elapsed in forming the profile. Columns 5 

 and 6 list the wave condition; ^o^^o ^^^ calculated using linear wave 

 theory and the reported condition, where necessary. Column 7 lists the 

 maximiim water depth in the test tank in the dimensionless form d^/L^, 

 where L^ is the maximum wavelength in the tank. Column 8 gives the 

 limit depth calculated from equation (5) for the listed H^/L_; value in 

 parentheses indicates the calculated depth is equal to or greater than 

 the column 7 depth. Column 9 gives the calculated limit depth, dg, 

 imless parentheses occur in column 8. Column 10 gives the cut depth, d^; 

 value in parentheses indicates the cut depth is uncertain, and a dash 

 indicates no clear cut occurred. Column 11 gives the percentage differ- 

 ence between dg and d^; the 27 values not in parentheses are the tests 

 included in Figure 3. Column 12 lists subjective profile classification.
