13. ABSTRACT (Maximum 200 words) 



The U.S. Army Engineer District, New York, is constructing Section I-Sea Bright to Ocean Township, New Jersey, of the 

 Atlantic Coast of New Jersey — Sandy Hook to Barnegat Inlet Beach Erosion Control Project. Within the initial portion of 

 this project, a zone of accelerated shoreline erosion has developed near the southern boundary of Monmouth Beach, 

 New Jersey. This report investigates shore-protection measures for the eroding beach with the goal of maintaining a 

 23-m-wide protective berm over the 6-year renourishment interval. The report evaluates performance of a nearby groin field 

 to establish groin design criteria, proposes and investigates the merits of five design alternatives employing a frequency-of- 

 violation criterion and the shoreline change model GENESIS, and recommends a functional design to reduce the high rate of 

 beach erosion.
