DOWNLOAD EBOOKBarrier 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 EBOOKThe evolution of barrier islands along the northern Gulf of Mexico coast is directly related to source of sediments and littoral processes. Johnson formulated his hypothesis on barrier island formation in 1919, and his theory prevailed for several decades. Johnson's theory resulted from consideration of only two dimensions normal to the coastline; a third, longshore drift, was not regarded as critical for the initiation of barrier island development. In this study, which is confined to the northern Gulf coast, major sources of sediment supply and transportation patterns of barrier forming sand were examined, along with results of recent oceanographic investigations in the Gulf of Mexico. This study is based on a comprehensive survey of the literature, maps, and marine charts, which were correlated with field observations. To obtain a perspective, only gross forms and processes of barrier development were considered. Evidence indicates that Santa Rosa Island, Mississippi Sound, and Bolivar Peninsula barriers developed downdrift of sediment-supplying coasts of Quaternary age. These barriers evolved with the Recent rise of sea level to its present stand. Apalachicola barriers formed on the flanks of the Pleistocene deltaic plain. Coasts such as the stretch between Destin and Panama City, Florida, and the zero-energy coast of Florida do not have barrier islands. In these cases the modern shoreline is abutted against Pleistocene deposits which are the local source of sediments. (Author).

DOWNLOAD EBOOKThis fully revised and updated edition introduces the reader to sedimentology and stratigraphic principles, and provides tools for the interpretation of sediments and sedimentary rocks. The processes of formation, transport and deposition of sediment are considered and then applied to develop conceptual models for the full range of sedimentary environments, from deserts to deep seas and reefs to rivers. Different approaches to using stratigraphic principles to date and correlate strata are also considered, in order to provide a comprehensive introduction to all aspects of sedimentology and stratigraphy. The text and figures are designed to be accessible to anyone completely new to the subject, and all of the illustrative material is provided in an accompanying CD-ROM. High-resolution versions of these images can also be downloaded from the companion website for this book at: www.wiley.com/go/nicholssedimentology.
