Summary/Conclusions 
Evolution of the beach fill between sta 255 and 275 (hot-spot region) 
indicates that shoreline recession at the hot spot is not a product of cross-shore 
sediment transport. In fact, little material was moved in the offshore direction. 
Net losses from these beach profiles suggest that the loss of material from the 
hot-spot region is due to longshore transport. Beach profiles to the north of the 
hot-spot region indicate significant gains of material during a period in which no 
beach-fill material was placed, thus support the idea of longshore losses. 
Additional shoreline retreat because of cross-shore sediment transport is not 
likely in the hot-spot region because of the beach profile’s near-equilibrium 
shape. However, additional shoreline retreat because of longshore transport 
cannot be dismissed. 
Beach profiles to the north of the hot spot, in the area that received material 
from the hot-spot region, are steeper than equilibrium and can be expected to 
adjust in the cross-shore sense towards the equilibrium beach profile if no 
additional material is deposited through longshore sediment transport.
