Environmental Design Guidelines For Low Crested Coastal Structures

The effect of manmade activities is primarily local but can extend far away from the location of intervention. This underlines the importance of establishing coastal zone management plans covering large stretches of coastlines. In recent years, interest in Low Crested Structures (coastal defense structures with a low-crest) has been growing together with awareness of the sensitivity to environmental impacts produced by coastal defenses. The relation between wave climate, beach erosion, beach defence means, habitat changes and beach value, which clearly exists based on EC research results, suggests the necessity of an integrated approach when designing coastal protection schemes. In accordance with this need, the present design guidelines cover structure stability and construction problems, hydro and morphodynamic effects, environmental effects (colonisation of the structure and water quality), societal and economic impacts (recreational benefits, swimming safety, beach quality). Environmental Design Guidelines for Low Crested Coastal Structures is specifically dedicated to Low Crested Structures, and provides methodological tools both for the engineering design of structures and for the prediction of performance and environmental impacts of such structures. A briefing of current best practice for local and national planning authorities, statutory agencies and other stakeholders in the coastal zone is also covered. Presented in a generic way, this book is appropriate throughout the European Union, taking into account current European Commission policy and directives for the promotion of sustainable development and integrated coastal zone management. * Fills the gap between engineering and ecology in coastal defense planning * Shows the reader how to perform an integrated design of coastal defense schemes * Presents latest insights on hydro-morphodynamics induced by structures * Provides directly applicable tools for the design of low crested structures * Highlights socio-economic perspectives in coastal defense design.

Coast lines have been and still are the central lines of civilization around the world with still increasing pressure from both sides – the hinterland and the sea – with all its foreseeable and unforeseeable impacts by means of nature or mankind. While the response of nature to such impacts is flexible in the way that all morphological changes with all the consequences are tolerated as part of the system, humanity cannot tolerate short-term or long-term changes without being threatened in its physical and economical existence. The objectives of this Advanced Research Workshop (ARW) on Environmentally Friendly Coastal Structures were: - to contribute to the critical assessment of existing knowledge in the field of coastal and environmental protection; - to identify directions for future research in that area; - to promote close working relationships between scientists from different countries and with different professional experience. The latest trends in research on coastal and environmental protection were summarized and developed during the meeting. Seventeen papers are presented in this book, attempting to cover all related aspects as completely as possible – coast, engineering structures, water, sediments, ecosystems in their complicated interaction.

Coastal Structures are undergoing renewal and innovation to better serve the needs of our society, from environmental co-existence and habitat enhancement to risk management. The CSt2011 conference is the sixth in a series that highlights coastal disaster preparedness and ocean utilization in a changing climate. The conferences have frequently yielded milestone works and highly cited references in the field.

Structure in the Sea: The Science, Technology and Effects of Purpose-Built Reefs and Related Surfaces provides a review of the history, development, status and emerging trends in research, technology and applications of artificial reef habitats and sea floor structures. The book helps readers understand, utilize and add to the research of modern reef deployment efforts, presenting a guide to equip stakeholders requiring technical foundations and best practices. Topics include materials, designs and construction methods, along with the ecology of these structures, including key aspects of the life history of plants and animals associated with artificial reefs. Rigorous research addressing ecological, economic and engineering questions, coupled with the innovative deployment of structures worldwide by diverse stakeholders, have created a synergy that makes the book a valuable synthesis and analysis for this growing subject. Thus, its broad audience includes marine (coastal and ocean) environmental sciences, including aquatic ecologists, those working in ocean sustainability and conservation, benthic habitat and coral reef restoration practitioners, and more. Presents a new perspective on how we might save natural wonders under threat Provides a representation of reefs, showing the economic and humanitarian value of these natural ecosystems Unlocks potentials for solutions for conservation by including global case studies

Existing coastal management and defense approaches are not well suited to meet the challenges of climate change and related uncertanities. Professionals in this field need a more dynamic, systematic and multidisciplinary approach. Written by an international group of experts, Coastal Risk Management in a Changing Climate provides innovative, multidisciplinary best practices for mitigating the effects of climate change on coastal structures. Based on the Theseus program, the book includes eight study sites across Europe, with specific attention to the most vulnerable coastal environments such as deltas, estuaries and wetlands, where many large cities and industrial areas are located. Integrated risk assessment tools for considering the effects of climate change and related uncertainties Presents latest insights on coastal engineering defenses Provides integrated guidelines for setting up optimal mitigation measures Provides directly applicable tools for the design of mitigation measures Highlights socio-economic perspectives in coastal mitigation
