Book excerpt: The littorals of the World are areas of great strategic importance. Approximately 95% of the world's population lives within 600 miles of sea, 80% of all countries border the coast and 80% of the world's capitals lie within 300 nautical miles of shore. With the end of the cold war, DoD's focus has shifted from a land/sea battle scenario with a monolithic global adversary to dealing with low-intensity conflicts in the near-coastal or littoral regions. In wartime, the ability to dominate the littoral, including the undersea environment, allows operating with impunity in the face of area denial threats while taking initial action to defeat those threats and prepare the battlespace for follow-on forces. information superiority - understanding and exploitation of the natural environment -- is critical to safe and effective operation of joint forces engage in littoral expeditionary warfare. The tactical advantage will probably depend not on who has the most expensive, sophisticated platforms - but rather in who can most fully exploit the natural advantages gained by a thorough understanding of the physical environment. Every aspect of the littoral environment is of critical import to conducting military operations, a huge challenge.

Book excerpt: The focus of critical U.S. programs on Homeland Security and Homeland Defense applications, and on the brown water navies of potential adversaries elicits a need for understanding and visualizing the near-shore land and maritime environments. The goal of this project is to develop a windows application that will provide a near real-time visual depiction of wave, wind, or other environmental elements' impact on the littoral environment that can be used as an aid to decision makers in their planning/response efforts. To achieve our goal we will use our latest commercially available PC-based military simulation. Our commercial off-the-shelf (COTS) naval strategy simulation, Sonalysts Combat Simulations - Dangerous Waters (registered trademark), includes high fidelity 3D micro-simulations of subsurface, surface, and air platforms that also include environmental characteristics such as day/night, currents, wind and stormy weather. The primary focus of this simulation is in the deep water environment. We will modify this engine as necessary to provide a realistic animation of the shallow water environment that exists within the littoral zone. We intend to show the feasibility of performing this shallow water visualization process through a proof of concept application developed during this Phase I period of nine months. This proof of concept will demonstrate a computer-based tool capable of providing fairly rapid rendering and realistic visualization of a littoral environment that is composed of varying elements such as wind speed and direction, wave height, periodicity, and direction.

Available in PDF, EPUB and Kindle. Book excerpt: Underwater Acoustic Modeling and Simulation, Fourth Edition continues to provide the most authoritative overview of currently available propagation, noise, reverberation, and sonar-performance models. This fourth edition of a bestseller discusses the fundamental processes involved in simulating the performance of underwater acoustic systems and emphasizes the importance of applying the proper modeling resources to simulate the behavior of sound in virtual ocean environments. New to the Fourth Edition Extensive new material that addresses recent advances in inverse techniques and marine-mammal protection Problem sets in each chapter Updated and expanded inventories of available models Designed for readers with an understanding of underwater acoustics but who are unfamiliar with the various aspects of modeling, the book includes sufficient mathematical derivations to demonstrate model formulations and provides guidelines for selecting and using the models. Examples of each type of model illustrate model formulations, model assumptions, and algorithm efficiency. Simulation case studies are also included to demonstrate practical applications. Providing a thorough source of information on modeling resources, this book examines the translation of our physical understanding of sound in the sea into mathematical models that simulate acoustic propagation, noise, and reverberation in the ocean. The text shows how these models are used to predict and diagnose the performance of complex sonar systems operating in the undersea environment.

Available in PDF, EPUB and Kindle. Book excerpt: Underwater Acoustic Modeling and Simulation examines the translation of our physical understanding of sound in the sea into mathematical models that can simulate acoustic propagation, noise and reverberation in the ocean. These models are used in a variety of research and operational applications to predict and diagnose the performance of complex sonar systems operating in the undersea environment. Previous editions of the book have provided invaluable guidance to sonar technologists, acoustical oceanographers and applied mathematicians in the selection and application of underwater acoustic models. Now that simulation is fast becoming an accurate, efficient and economical alternative to field-testing and at-sea training, this new edition will also provide useful guidance to systems engineers and operations analysts interested in simulating sonar performance. Guidelines for selecting and using available propagation, noise and reverberation models are highlighted. Specific examples of each type of model are discussed to illustrate model formulations, assumptions and algorithm efficiency. Instructive case studies demonstrate applications in sonar simulation.

Available in PDF, EPUB and Kindle. Book excerpt: Simulating Nearshore Environments provides computer procedures that realistically represent nearshore processes and supplement or replace trial and error methodology. The procedures simulate transport by waves and fluvial processes on beaches and deltas at various scales. They will aid coastal engineers, oceanographers and sedimentary geologists who focus on both modern and ancient nearshore deposits. How do you simulate nearshore processes using a computer? Can evolving deltaic and coastal environments be simulated realistically by mathematically representing the physical processes that create them? Once the physics and mathematical formulation are described, what are the techniques for transforming them into computer programs? The authors deal with all these aspects and take a "how to" approach in guiding the reader through the development of computer models for simulating sediment transport in coastal environments. In addition to describing the devised computer programs, the book provides a basis for those wishing to formulate their own mathematical models for simulating nearshore processes.
