Coastal Defences aims to present the broad spectrum of methods that engineers use to protect the coastline and investigates the sorts of issues that can arise as a result. The first section of the book examines 'traditional' hard techniques, such as sea walls and groynes, whilst the second looks at the more recent trend of using techniques more sympathetic to nature. By looking at each of the main methods of coastal protection in detail, the book investigates the rationale for using each method and the consequent management issues, presenting a case for and against each of the techniques.

In the late-19th century, with the advances in technology and the increase in America's economic stature, a new round of fortification building began in the United States and its overseas territories. Locations such as Portland, Boston, New York, Baltimore, Charlestown, Savannah, Key West, Los Angeles and San Francisco were all extensively fortified. This book provides a concise introduction to the design, development and purpose of American coastal defenses in the "modern" era (1885–1950), a period defined by the use of concrete, steel, and powerful breech-loading rifles. It covers the emplacements, weaponry, equipment, and people that defended their country in times of great change and uncertainty.

These conference proceedings from the coastal management conference include information on policy including the House of Commons Environment Committee Report on coastal zone protection and planning, a number of consultative documents, and details on new guidelines and policies which have had a significant impact on the coastal community.

More and more of the nation's vast coastlines are being filled with homes and vacation resorts. The result is an increasing number of structures built on erosion-prone shoresâ€"with many of these structures facing collapse or damage. In response to mounting property losses, Congress has given the Federal Emergency Management Agency responsibility for incorporating coastal erosion into its National Flood Insurance Program (NFIP). This book from the National Research Council addresses the immediate question of how to develop an erosion insurance programâ€"as well as the larger issues raised by the continually changing face of our nation's shorelines. Managing Coastal Erosion explores major questions surrounding a national policy on coastal erosion: Should the federal government be in the business of protecting developers and individuals who build in erosion-prone coastal areas? How should such a program be implemented? Can it prompt more responsible management of coastal areas? The volume provides federal policymakers, state floodplain and resource managers, civil engineers, environmental groups, marine specialists, development companies, and researchers with invaluable information about the natural processes of coastal erosion and the effect of human activity on those processes. The book also details the workings of the NFIP, lessons to be learned from numerous state coastal management programs, and much more.

This volume presents the proceedings of the fifth international conference on coastal mangement, held 15-17 October 2003 in Brighton. The purpose of the conference was to translate policy into practice in terms of the management of coastal zones within the overall goal of achieving sustainable development. The objectives of the conference were fully supported by the Eurpean Commission and Defra, the lead government department for coastal issues in the UK.

Managed realignment has been a preferred coastal management strategy in England in the 21st century and has also been increasingly implemented elsewhere. Climate change and environmental and financial concerns have led to a shift from the traditional ‘hold-the-line’ approach of coastal protection towards more flexible soft engineering options. Managed realignment is a relatively new soft engineering alternative aiming to provide sustainable flood risk management with added environmental and socio-economic benefits by creating space for coastal habitats to develop more dynamically. The natural adaptive capacity of coastal habitats and the ecosystem services they provide underpin the sustainability of managed realignment. However, many definitions of managed realignment exist and the understanding of what the term actually represents in practice has evolved through time and varies regionally. This book clarifies the definitions and terminology used in the literature and proposes that managed realignment is used as a general term that encompasses the many different methods of implementation worldwide, including: removal, breach and realignment of defences; controlled tidal restoration (which includes regulated tidal exchange and controlled reduced tide); and managed retreat. These methods of implementation are explained and illustrated with examples from around the world. In addition to a general overview of emerging policies and current practices, specific chapters discuss approaches adopted in different locations, including the Netherlands, the UK and Maui (USA). The UK experience is presented from the perspectives of three sectors: the National Trust (a charity organisation that owns 10% of the coastline of England and Wales), the Environment Agency (the organisation responsible for implementing government policy concerning flood and erosion risk) and a private consultant involved in the planning, design and delivery of managed realignment projects. Taking a wider perspective to consider the range of implementation methods, the viability of managed realignment as a long-term coastal management strategy is discussed. Recent national and regional strategies worldwide give managed realignment an increasing role in climate change and flood risk management. Gaining stakeholders and public support is fundamental for the success of emerging coastal management strategies. However, public perception and stakeholders engagement are often cited as a factor limiting the wider uptake of managed realignment. Results from a recent survey are used to benchmark the current thinking about the potential, the performance and the limitations of managed realignment in the UK and elsewhere. Current opinions about managed realignment are often not clearly defined, partly due to many projects being relatively recent. There is a general perception of great potential to provide sustainable flood risk management with added environmental benefits. However, the views of stakeholders are considerably more negative and notably contrast with the views of practitioners and researchers. The only clear and dominant agreement across all groups of respondents is that better understanding about the long-term evolution of sites is needed.
