30. The total transport rate per unit width 1 at a particular trap Is 

 calculated by using the determined fluxes and distances Aa(k) between 

 nozzles : 



N-l 



(3) 



1 = Ah y F(k) + Y Aa(k)FE(k) 



in which N is the total number of streamers on the trap. The first summa- 

 tion term represents the actual measured fluxes and the second summation term 

 represents the interpolated fluxes between nozzles. If traps were placed on a 

 line across the surf zone, transport rates per unit width were calculated with 

 Equation 3 , and the trapezoid rule was used to compute the total longshore 

 sand transport rate across the surf zone. Elevations of the streamers above 

 the bed are listed in Table Al of Appendix A, and locations of the traps in 

 the surf zone are given in Table A2 .
