20. ABSTRACT (Conttnue on. rovers* eitta ft necessary and Identity by block number) 



Oregon Inlet is a large tidal inlet through the barrier island system of 

 North Carolina. In 1970, Congress authorized the Manteo (Shallowbag) Bay pro- 

 ject which had provisions to stabilize Oregon Inlet with two jetties, deepen the 

 ocean bar channel to 20 ft, and bypass across the inlet sand intercepted by the 

 jetties. This report describes the results of a numerical study to consider 

 coastal and inlet processes in the region surrounding the inlet under existing 

 and planned project conditions. To accomplish the objectives of the study, a
