Book Description
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.

Book Description
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.

Book Description
With the improved understanding of coastal processes and the availability of very high speed computers and efficient computation techniques, it is now economically feasible to use numerical modeling systems to study the impact of large-scale engineering works on coastal processes. Such systems have the advantage that, unlike physical hydraulic and movable-bed models, once the systems are built and tested, they can be applied to different prototype sites with much less additional effort and cost. Also, they can be used to examine several different problems such as the effects of coastal structures, disposal of dredged material, modification of navigation channels, and estimating maintenance dredging requirements. In this paper, the development of one such modeling system at the US Army Engineer Waterways Experiment Station (WES), Coastal Engineering Research Center (CERC), is described. The system, known as the Coastal and Inlet Processes (CIP) Modeling System, was developed in response to the long-term needs of the Corps of engineers.

Hydrodynamics and Sediment Dynamics of Tidal Inlets

Book Description
Along much of the shoreline of the world, tidal inlets play an important role in nearshore processes, providing links between the coastal oceans and protected embayments. Their study is of particular importance not only for the understanding of fundamental processes in coastal oceanography but also for engineering and the proper management of the delicate equilibrium of our shorelines. This volume, based on the International Symposium on Hydrodynamics and Sediment Dynamics of Tidal Inlets held at Woods Hole, MA, presents the reader with an overview of contemporary research on these important features. The coverage includes: - mathematical modelling, including a review of inlet hydrodynamics, - observations on hydrodynamics, - sedimentology and morphology, - tidal deltas, - processes and policies pertaining to sedimentation, and the - impacts of shore protection and dredging in beaches.
