Figure 18. Beach profile evolution at sta 275 
Beach profiles at sta 286, 290, and 294 indicate similar patterns of evolution 
as sta 265 and 275, but have net sediment losses of 70, 36, and 36 cu yd/ft, 
respectively (significantly smaller than the losses at sta 265 and 275). These 
profiles are given in Appendix B. 
A consistent pattern within the general region of the hot spot is significant 
losses of material from the beach profiles with little or no cross-shore profile 
adjustment. This indicates that the loss of material from the hot-spot region is 
related to longshore transport processes instead of cross-shore transport 
processes. 
North of hot spot 
No beach-fill construction was completed north of the hot-spot region before 
beach-fill placement ended for the season on 3 January 1995. Beach-fill 
construction at this time advanced only as far north as the base of Coastal 
Structure 44.' Before construction resumed in April 1995, all stations along the 
beach-fill reference line were surveyed. The March 1995 profile surveys north 
of Groin 44 reveal that a large volume of material accumulated between 
December 1994 and March 1995. This indicates that a significant amount of 
material lost from the hot-spot region was transported north and deposited in the 
adjacent region to the north. Profiles 208, 232, 240, and 245 are presented to 
demonstrate the effect of the evident longshore transport.
