Conclusions 
Evaluation of the planform evolution of the beach-fill project in the vicinity 
of the hot spot supports the findings of the beach-fill end-loss analysis. The 
visualization of measured beach profile data in a three-dimensional model 
reveals that material lost from the hot-spot region was gained in the sediment- 
starved profiles to the north as indicated by elevation change between the 
October 1994 and March 1995 bathymetric models. Analysis of the evolution of 
the mhw shoreline reveals that the seaward protrusion of the beach fill in the hot- 
spot region adjusted to the general shape and orientation of the -20-ft prefill 
contour. Now that longshore beach-fill adjustment has smoothed the shoreline, 
erosion rates within the hot-spot region are expected to decrease.
