somewhat shoreward of the break point, and ending where the wave decay model 

 calculation was arbitrarily stopped. For each case, various quantities 

 connected with the energy flux dissipation were correlated with the cross - 

 shore sand transport rate in Zone III for all distributions obtained during a 

 run. The net cross -shore transport rate showed good correlation with energy 

 flux dissipation per unit water volume for all cases studied (correlation 

 coefficients of 0.7-0.8), which was higher than the correlation resulting from 

 tests using only the energy flux dissipation per unit area of beach. 

 Figure 49 shows the transport rate plotted against the energy flux dissipation 

 per unit volume as evaluated for Case 6-1.

 distributions than if all values from a specific case were used. Other 

 parameters pertaining to the geometry of the beach profile, such as beach 

 slope and wave characteristics, were also correlated with the transport rate. 

 To determine geometric parameters of the beach profile, the average profile
