Beach erosion is a chronic problem along open-ocean shores of the U.S. As coastal populations continue to grow and community infrastructures are threatened by erosion, there is increased demand for accurate info. regarding past and present trends and rates of shoreline movement, and a need for a comprehensive analysis of shoreline movement. This report on states bordering the Gulf of Mexico (Florida, Alabama, Mississippi, Louisiana, and Texas) summarizes the methods of analysis, interprets the results, provides explanations regarding the historical and present trends and rates of change, and describes how different coastal communities are responding to coastal erosion in 2004 (prior to Hurricanes Katrina and Rita).

The changing focus and approach of geomorphic research suggests that the time is opportune for a summary of the state of discipline. The number of peer-reviewed papers published in geomorphic journals has grown steadily for more than two decades and, more importantly, the diversity of authors with respect to geographic location and disciplinary background (geography, geology, ecology, civil engineering, computer science, geographic information science, and others) has expanded dramatically. As more good minds are drawn to geomorphology, and the breadth of the peer-reviewed literature grows, an effective summary of contemporary geomorphic knowledge becomes increasingly difficult. The fourteen volumes of this Treatise on Geomorphology will provide an important reference for users from undergraduate students looking for term paper topics, to graduate students starting a literature review for their thesis work, and professionals seeking a concise summary of a particular topic. Information on the historical development of diverse topics within geomorphology provides context for ongoing research; discussion of research strategies, equipment, and field methods, laboratory experiments, and numerical simulations reflect the multiple approaches to understanding Earth’s surfaces; and summaries of outstanding research questions highlight future challenges and suggest productive new avenues for research. Our future ability to adapt to geomorphic changes in the critical zone very much hinges upon how well landform scientists comprehend the dynamics of Earth’s diverse surfaces. This Treatise on Geomorphology provides a useful synthesis of the state of the discipline, as well as highlighting productive research directions, that Educators and students/researchers will find useful. Geomorphology has advanced greatly in the last 10 years to become a very interdisciplinary field. Undergraduate students looking for term paper topics, to graduate students starting a literature review for their thesis work, and professionals seeking a concise summary of a particular topic will find the answers they need in this broad reference work which has been designed and written to accommodate their diverse backgrounds and levels of understanding Editor-in-Chief, Prof. J. F. Shroder of the University of Nebraska at Omaha, is past president of the QG&G section of the Geological Society of America and present Trustee of the GSA Foundation, while being well respected in the geomorphology research community and having won numerous awards in the field. A host of noted international geomorphologists have contributed state-of-the-art chapters to the work. Readers can be guaranteed that every chapter in this extensive work has been critically reviewed for consistency and accuracy by the World expert Volume Editors and by the Editor-in-Chief himself No other reference work exists in the area of Geomorphology that offers the breadth and depth of information contained in this 14-volume masterpiece. From the foundations and history of geomorphology through to geomorphological innovations and computer modelling, and the past and future states of landform science, no "stone" has been left unturned!
One of 21 climate change synthesis and assessment products commissioned by the U.S. Climate Change Science Program (CCSP), this report examines the effects of sea level rise, impacts on society, and opportunities to prepare for those consequences, focusing on the eight coastal states from New York to North Carolina. Using scientific literature and policy documents, the report describes potential changes to barrier.
This book covers the gamut of coastal hazards that result from short-term low-frequency events and have high-magnitude and far-reaching impacts on coastal zones the world over. Much of the world’s population now lives in low-lying coastal zones that are inherently vulnerable to natural hazards such as flooding from hurricanes, tropical storms and northeastern storm surges; shoreline (beach and dune) erosion; cliff and bluff failures; and saltwater intrusion in coastal aquifers used for drinking water supplies. In addition to the usual range of hydrometeorological disasters in coastal zones, this book covers tsunami impacts and warning systems as well as global perspectives of sea-level rise impacts and human perceptions of potential vulnerabilities resulting from rip currents that cause many drownings each year on beaches. Today, the use of numerical models that help predict vulnerabilities and provide a basis for shore protection measures is important in modern scientific and engineering systems. Final considerations focus on human actions in the form of the urbanization and industrialization of the coast, shore protection measures, and indicate how environmental degradation around coastal conurbations exacerbates the potential for unwanted impacts. Strategies for environmental management in coastal zones, from low-lying wetlands to high cliffs and rocky promontories, are highlighted as a means of living in harmony with Nature and not trying to conquer it.
This book will help you explore the origins of coastal features, such as barrier islands, sand beaches and coastal dunes. It unravels the wonderful mystery of how the extensive Georgia salt marshes evolved. Furthermore, it explains the changing face of the coastline through deposition and erosion during major storms. The key ecological resources are described in detail for each of the major subdivisions of the coast. Through richly illustrated diagrams, full-color photographs, and satellite images this general treatment of the coastal geology and ecology of Georgia will help you understand this exceptional coast through a delightful and completely comprehensible narrative.
Remaking Boston chronicles many of the events that altered the physical landscape of Boston, while also offering multidisciplinary perspectives on the environmental history of one of America's oldest and largest metropolitan areas.
The new revised fifth edition of Natural Hazards remains the go-to introductory-level survey intended for university and college courses that are concerned with earth processes that have direct, and often sudden and violent, impacts on human society. The text integrates principles of geology, hydrology, meteorology, climatology, oceanography, soil science, ecology, and solar system astronomy. The textbook explains the earth processes that drive hazardous events in an understandable way, illustrates how these processes interact with our civilization, and describes how we can better adjust to their effects. Written by leading scholars in the area, the new edition of this book takes advantage of the greatly expanding amount of information regarding natural hazards, disasters, and catastrophes. The text is designed for learning, with chapters broken into small consumable chunks of content for students. Each chapter opens with a list of learning objectives and ends with revision as well as high-level critical thinking questions. A Concepts in Review feature provides an innovative end-of-chapter section that breaks down the chapter content by parts: reviewing the learning objectives, summary points, important visuals, and key terms. New case studies of hazardous events have been integrated into the text, and students are invited to actively apply their understanding of the five fundamental concepts that serve as a conceptual framework for the text. Figures, illustrations, and photos have been updated throughout. The book is designed for a course in natural hazards for nonscience majors, and a primary goal of the text is to assist instructors in guiding students who may have little background in science to understand physical earth processes as natural hazards and their consequences to society.
The interaction between land and sea is controlled by a number of processes that are in general driven by the equilibrium between environmental forcing components (e.g. hydrodynamic - waves, currents, surges), atmospheric (e.g. winds) and terrestrial (e.g. catchment land cover) and sediment dynamics. In the context of the Anthropocene epoch, the equilibrium in many coastal regions is now often altered by the influence of human activities. Successive human activities globally influence (indirectly) these forcing components, helping magnify the negative impact of extreme meteorological events and sea level rise. Directly, human activity can also influence a number of processes at a local scale within and between the catchment, the sea and the coast. For example, misplaced engineered infrastructure inside these naturally dynamic environments can accentuate disequilibrium, destabilizing shores and deltas. Development in catchments can promote rapid runoff, inducing sometimes-dramatic effects on downstream urbanized areas, the socio-economy as well as on coastal resources and ecosystems. This Research Topic aims to assemble research and review papers that focus on the dynamics of shores and deltas in peril under present conditions as well as in the future context of sea-level rise, climate change and adaptation strategies under various scenarios.
