Book Description
The numerical model documented here, RCPWAVE, can be used to solve wave propagation problems over arbitrary bathymetry. The governing equations solved in the model are the mild slope equation for linear, monochromatic waves, and the equation specifying irrotationality of the wave phase function gradient. Finite difference approximations of these equations are solved to predict wave propagation outside the surf zone. Inside the breaker zone, an empirical method is used to predict wave transformation. This method is based on a hydraulic jump representation of the entire surf zone. The model is verified using laboratory and field data. A user's manual section is provided to aid potential users. This documentation describes job control language files, job submission procedures, sample input and output files, and execution costs.
Coastal and Inlet Processes Numerical Modeling System for Oregon Inlet, North Carolina

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
This book systematizes the concepts of contemporary coastal zone management and suggests possible structural and non-structural management tools for decision-making processes. Some successful adaptation measures and case studies on oceanic processes and coastal protection are discussed. High-frequency communications in coastal and marine environments are also addressed.All chapters contribute relevant information and useful content to scientists and other readers interested or concerned about the lack of adequate management actions and the installation of appropriate protections or their ineffectiveness in containing coastal vulnerabilities and risks.

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.

Guide to Process Based Modeling of Lakes and Coastal Seas

Pages : 291
Book Description
This new edition of Guide to Process Based Modeling of Lakes and Coastal Seas brings the modeling up to date, taking into account multiple stressors acting on aquatic systems. The combination of acidification and increasing amounts of anoxic waters associated with eutrophication puts severe stress on the marine environment. The detection and attribution of anthropogenic changes in coastal seas are therefore crucial and transparent modeling tools are increasingly important. Modeling the marine CO2–O2 system makes systematic studies on climate change and eutrophication possible and is fundamental for understanding the Earth system. This second edition also includes new sections on detection and attribution and on modeling future changes, as well as improved exercises, updated software, and datasets. This unique book will stimulate students and researchers to develop their modeling skills and make model codes and data transparent to other research groups. It uses the general equation solver PROBE to introduce process-oriented numerical modeling and to build understanding of the subject step by step. The equation solver has been used in many applications, particularly in Sweden and Finland with their numerous lakes, archipelago seas, fjords, and coastal zones. It has also been used for process studies in the Polar Seas and the Mediterranean Sea and the approach is suitable for applications in many other environmental applications. Guide to Process Based Modeling of Lakes and Coastal Seas: • is a unique teaching tool for systematic learning of aquatic modeling; • approaches lake and ocean modeling from a new angle; • introduces aquatic numerical modeling using a process-based approach; • enables the thorough understanding of the physics and biogeochemistry of lakes and coastal seas; • provides software, datasets, and algorithms needed to reproduce all calculations and results in the book; • provides a number of creative and stimulating exercises with solutions; • addresses the interaction between climate change and eutrophication and is a good basis for learning Earth System Sciences.
