This collection of papers offers a new approach to nearshore and estuary studies, with an emphasis on multidisciplinary techniques and data integration. The important results of these studies are accompanied by full color images.
Barrier islands represent a complex coastal system that includes a number of different sedimentary depositional environments; nearshore zone, beach, dunes, washover fans, marshes, tidal flats, estuaries, lagoons, and tidal inlets. The morphodynamics of these fragile coastal systems provide a further complication to this coastal type. Although barrier islands comprise only 15% of the world's coastline, they have received a far greater proportion of attention from the scientific and engineering community, and more recently, from coastal managers and environmentalists. Modern barrier islands are arguably the most expensive and most vulnerable of all coastal environments. Pressure from developers for residential, industrial, and recreational development has caused most of our barriers to become significantly impacted by human activity, especially over the past few decades. These pres sures have led to extensive preservation of natural barriers through efforts from all levels of government and also by private organizations. Governments have also formed coastal management programs that help to control any future de velopment with the intent being to keep human activity compatible with barrier island morphodynamics. In order to devise appropriate coastal zone management programs, it is necessary to have a comprehensive understanding of the morpho dynamics of barrier island systems. This volume provides comprehensive details on barrier island morphology, sediment distribution, and the process-response mechanisms that cause changes to both. These are the important aspects of barrier systems that can provide important input into the development and implementation of coastal management programs.
Maine is known for its rockbound coast and pristine shoreline. Yet there is more to this shore than rocky cliffs. This book describes the origin of the more common "soft coast" of eroding bluffs, sand beaches, and salt marshes. A central theme is the formation of the present shoreline during the current ongoing rise in sea level and the ways in which coastal residents can best cope with the changes to come. Although it is not widely known, Maine is experiencing a rapid, uneven drowning of its shore at the same time that coastal development is at an all-time high. The authors explain how the shoreline is changing and provide a series of highly detailed maps that show the relative safety of particular locations on the coast. Specific guidelines for recognizing various safe and unsafe coastal settings are presented, as are recommendations for sound construction techniques in hazardous coastal areas. Photographs and drawings illustrate the danger of living too near the shoreline, and an up-to-date review of Maine's regulations governing coastal construction is simply and readably described. A bibliography of important coastal literature is also included, as well as a guide to federal, state, and local sources of information.
Glaciated Coasts is a collection of articles that deals with shoreline morphologies of glaciated coasts and the processes that formed these coastlines in North America. This book examines nonsandy shorelines and covers a range of geologic and geographic coastal settings in a northern-southern order. This text investigates and compares the glaciated northern shorelines. These shorelines north of the glacial limit are mostly of the primary form in different stages of modification by marine agents. Shorelines are associated with embayments; baymouth barriers in turn enclose embayments. This book describes beaches as having coarse or mixed sediment populations. Most beaches worldwide have gravel clasts that have been rounded and sorted by marine processes. In the southeastern coast of Alaska, active tectonics on a mountainous shoreline is evident. The region also shows emergent and submerging shorelines with a glacial imprint undergoing formation by modern processes. This book also gives examples of gravel beach environments in various coastal settings. This book can prove useful for students of meteorology, oceanography as well as to marine ecologists and biologists. It can also benefit readers whose interest lie with coastal environment or with the general earth sciences.
The Archaeology of Prehistoric Coastlines offers a conspectus of recent work on coastal archaeology examining the various ways in which hunter-gatherers and farmers across the world exploited marine resources such as fish, shellfish and waterfowl in prehistory. Changes in sea levels and the balance of marine ecosystems have altered coastal environments significantly over the last ten thousand years and the contributors assess the impact of these changes on the nature of human settlement and subsistence. An overview of coastal archaeology as a developing discipline is followed by ten case studies from a wide variety of places including Scandinavia, Japan, Tasmania and New Zealand, Peru, South Africa and the United States.
