28. If traps are positioned across the surf zone, the total longshore 

 sand transport rate through the surf zone can be estimated using the distances 

 between traps, the transport rate density i at each trap, and the trapezo- 

 idal rule applied over the distance between the shoreline and the average wave 

 breaker line.
