This book was released on 2012-12-06 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Geology and Geomorphology of Holocene Coastal Barriers of Brazil written by Sérgio R. Dillenburg and published by Springer Science & Business Media. This book was released on 2008-11-20 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book to cover the Holocene geology and geomorphology of the 9,200 kilometers of the Brazilian coast. It is written for third and fourth year undergraduates, post-graduate students, scientists and man- ers. It characterizes the Brazilian coast in terms of the Holocene geology, geomorphology, oceanographic and climatic conditions, and the location, morphology and evolution of the barrier types. Separate chapters outline the types of barriers and coastal dynamics in each state, beginning in the south and proceeding to the north. Some emphasis is placed on the stretches of coast where the detailed morphology and stratigraphy of b- riers has been previously determined. To date, the Brazilian coastal barriers have been largely ignored by the international community, partly perhaps because much of the past research has tended to concentrate on barrier islands, of which there are very few in Brazil. In contrast, the Brazilian coastal barriers display a much wider range of types than is generally assumed. The biggest and most spectacular transgressive dunefield barriers in the world exist in Brazil, and dominate the southern and northeastern coasts. Many have never been described - fore. This volume provides a wealth of information on Holocene barrier types, evolution and dynamics. It provides managers, ecologists, biologists and botanists with much needed information on the geology, geomorph- ogy and dynamics of the genesis, types, functioning and ecosystems of the Holocene barriers extending along the entire Brazilian coast.
Download or read book Quaternary History of the Coorong Coastal Plain Southern Australia written by Colin V. Murray-Wallace and published by Springer. This book was released on 2018-04-28 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an up-to-date overview of the Quaternary geological and geomorphological evolution of the Coorong Coastal Plain region and its significance in a global context for understanding long-term records of Quaternary sea-level changes. The Coorong Coastal Plain in southern Australia is a natural laboratory for examining the response of coastal barrier landscapes to relative sea-level changes. The region provides direct evidence of coastal sedimentation during successive interglacials over the past 1 million years, as well as more recent volcanism. The region has received international focus and attracted scientists from around the World, with interests in long-term coastal evolution, sea-level changes, Quaternary dating methods and geochronology, soil development, temperate carbonate sedimentation, karst geomorphology and geologically recent volcanism.

Available in PDF, EPUB and Kindle. Book excerpt: The zone where land and sea meet is composed of a variety of complex environments. The coastal areas of the world contain a large percentage of its population and are therefore of extreme economic importance. Industrial, residential, and recreational developments, as well as large urban complexes, occupy much of the coastal margin of most highly developed countries. Undoubtedly future expansion in many undeveloped maritime countries will also be concentrated on coastal areas. Accompanying our occupation of coasts in this age of technology is a dependence on coastal environments for transportation, food, water, defense, and recreation. In order to utilize the coastal zone to its capacity, and yet not plunder its resources, we must have extensive knowledge of the complex environments contained along the coasts. The many environments within the coastal zone include bays, estuaries, deltas, marshes, dunes, and beaches. A tremendously broad range of conditions is represented by these environments. Salinity may range from essentially fresh water in estuaries, such as along the east coast of the United States, to extreme hypersaline lagoons, such as Laguna Madre in Texas. Coastal environments may be in excess of a hundred meters deep (fjords) or may extend several meters above sea level in the form of dunes. Some coastal environments are well protected and are not subjected to high physical energy except for occasional storms, whereas beaches and tidal inlets are continuously modified by waves and currents.

Download or read book Barrier Dynamics and Response to Changing Climate written by Laura J. Moore and published by Springer. This book was released on 2018-01-17 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents chapters, written by leading coastal scientists, which collectively depict the current understanding of the processes that shape barrier islands and barrier spits, with an emphasis on the response of these landforms to changing conditions. A majority of the world’s population lives along the coast at the dynamic intersection between terrestrial and marine ecosystems and landscapes. As narrow, low-lying landforms, barriers are especially vulnerable to changes in sea level, storminess, the geographic distribution of grass species, and the rate of sand supply—some barriers will undergo rapid changes in state (e.g., from landward migrating to disintegrating), on human time scales. Attempts by humans to prevent change can hasten the loss of these landforms, threatening their continued existence as well as the recreational, financial and ecosystem service benefits they provide. Understanding the processes and interactions that drive landscape response to climate change and human actions is essential to adaptation. As managers and governments struggle to plan for the future along low-lying coasts worldwide, and scientists conduct research that provides useful guidance, this volume offers a much-needed compilation for these groups, as well as a window into the science of barrier dynamics for anyone who is generally interested in the impacts of a changing world on coastal environments.

Download or read book Response of Upper Gulf Coast Estuaries to Holocene Climate Change and Sea level Rise written by John B. Anderson and published by Geological Society of America. This book was released on 2008-01-01 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the main impacts of global warming is accelerated sea-level rise: Intergovernmental Panel on Climate Change predictions suggest that the rate of rise could reach as high as 5'10 mm/yr by the end of this century. While it is generally recognized that accelerated sea-level rise will severely impact low-gradient coastlines, scientists are still ill prepared to predict coastal response. A study of seven Gulf Coast estuaries (Mobile Bay and Mississippi Sound, Weeks Bay, Calcasieu Lake, Sabine Lake, Galveston Bay, Matagorda Bay, and Corpus Christi Bay) was aimed at examining their response to past changes in the rate of sea-level rise and climate. The rates of change are of the same magnitude as those predicted for this century. The estuarine response to change has been one of abrupt landward retreat and major reorganization of estuarine environments at decadal time scales. This book should be of interest to scientists and policy makers concerned with future impacts of global warming.

Download or read book Inland Dunes of North America written by Nicholas Lancaster and published by Springer Nature. This book was released on 2020-05-20 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inland sand dunes are widespread in North America and are found from the North Slope of Alaska to the Sonoran Desert in northern Mexico and from the Delmarva Peninsula in the east to Southern California in the west. In this edited book, we highlight recent research on areas of inland dunes that span a range from those that are actively accumulating in current conditions of climate and sediment supply to those that were formed in past conditions and are now degraded relict systems. This book will be of interest to researchers and scholars of physical geography, geomorphology, environmental sciences, and earth sciences. Contributions include detailed analyses of individual active dune systems at White Sands, New Mexico; Great Sand Dunes, Colorado; and the Laurentian Great Lakes; as well as the vegetation-stabilized dunes of the Nebraska Sand Hills and the Colorado Plateau. Additional chapters discuss the widespread partially vegetated dune systems of the central and southern Great Plains; the relict dunes of the Atlantic Coastal Plain of the eastern USA; and active and stabilized dunes of the Colorado Plateau and the southwestern deserts of the USA and northern Mexico.
