boundaries of the new coarse zone were located a minimum of 30 meters landward 

 of the adjacent upcurrent disposed sediment indicating the disposal sediment had 

 moved both onshore and alongshore. 



Although no attempt was made to measure sediment texture for the beach and 

 inshore zones through time, major textural changes were observed to occur in the 

 trough and bar region. On some days, particularly following strong surf con- 

 ditions, the trough became choked with coarse sediment identical in appearance 

 to that of the disposed sediment. This coarse material occurred throughout the 

 trough bar area and extended downcurrent far beyond the inshore zone of the 

 study area. 



DISCUSSION ON TRANSPORT OF DISPOSED SEDIMENT 



1 . General 



A synthesis of profile shape, volume, and textural data provides evidence 

 for determining the primary transport direction of the disposal material. The 

 shore-normal and shore-parallel components of net sediment movement represent 

 the combined result of both fair-weather transport processes and transport
