Oregon Inlet is a large tidal inlet through the barrier island system of North Carolina. In 1970, Congress authorized the Manteo (Shallowbag) Bay project 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 system of numerical models called Coastal and Inlet Processes (CIP) Numerical Modeling System was developed. It included models for wave propagation, wave-induced currents and setup, sediment transport within and beyond the surf zone, and profile response (onshore-offshore transport). Results from a separate study on numerical simulation of tides and storm surge for Oregon Inlet were utilized in the present investigation.

Much of the U.S. coastline is rapidly changingâ€"mostly eroding. That fact places increasing pressure on the planners and managers responsible for coastal development and protection, and could have a direct effect on many of the 125 million Americans living within 50 miles of the coast who rely on its resources and beaches for their livelihood or recreation. Although rapid advances have been made in the measurement systems needed to understand and describe the forces and changes at work in the surf-zone environment, their potential for allowing more accurate and reliable planning and engineering responses has not been fully realized. This book assesses coastal data needs, instrumentation, and analyses, and recommends areas in which more information or better instrumentation is needed.
