1 3. ABSTRACT (Maximum 200 words) 



The U.S. Army Engineer District, New York, is conducting several shore protection studies along the south shore of Long 

 Island, New York. Shinnecock Inlet is the easternmost of six openings in the barrier island chain that runs along the south 

 shore of Long Island and the inlet falls within the largest shore protection effort, the "Fire Island to Montauk Point Reformula- 

 tion Study (FIMPRS)." Under FIMPRS, coastal processes, shore protection, and flood damage reduction alternatives are being 

 examined from Fire Island Inlet eastward to Montauk Point. This report discusses the geologic history of the inlet and using 

 the results of a coastal processes study, evaluates ebb shoal morphology and longshore transport processes as they relate to 

 sand management (bypass) options. Five bypass options are evaluated based on cost, operational effectiveness, and sand source 

 location. A decision matrix is included to compare alternatives.
