Beach Nourishment: Theory And Practice


Book Description

This book is written for engineers, students of coastal processes and laypersons interested in beach nourishment, which consists of the placement of large quantities of good quality sediment on the beach to advance the shoreline seaward. The improvement of project performance through proper design and the predictability of performance are emphasized. The overall longevity of a project is addressed as are local erosional areas. The roles which wave height, project length and sediment quality play in project performance are addressed quantitatively. The results are illustrated through reference to a number of monitored nourishment projects. Biological and economic aspects of beach nourishment are addressed.




Shore Processes and their Palaeoenvironmental Applications


Book Description

The last five years have been marked by rapid technological and analytical developments in the study of shore processes and in the comprehension of shore deposits and forms, and shoreline change over time. These developments have generated a considerable body of literature in a wide range of professional journals, thus illustrating the cross-disciplinary nature of shore processes and the palaeo-environmental dimension of shore change. The justification of the book lies in bringing together these developments using an objective approach that synthesises current advances, technical progress in the analysis of shores and shore processes, contradictory interpretations, and potential advances using future-generation developments in techniques. The book provides a comprehensive state-of-the-art presentation of shore processes and deposits across ranges of wave energy and tide-range environments, sediment supply and textural conditions, sea-level change, exceptional events and longer-term climate change, based on the most recently published literature in the marine sciences. The book insists on the nested time and spatial scales through which are inter-linked shore processes and deposits, thus providing a better understanding of the way shores change over time. The approach is thus cross-disciplinary, and gap-bridging between processes and deposits, between analytical techniques, and between timescales. The audience is from graduate level upwards, and the book is intended as a comprehensive reference source for professionals in a wide range of coastal science fields (geologists, sedimentologists, geomorphologists, oceanographers, engineers, managers, archaeologists...).* Aimed at graduates and specialists interested in coastal science* Presents background research, recent developments and future trends* Written by a leading scholar and industry expert




Coastal Processes with Engineering Applications


Book Description

Text on coastal engineering and oceanography covering theory and applications intended to mitigate shoreline erosion.




Soft Shore Protection


Book Description

Global warming, melting polar caps, rising sea levels and intensifying wave-current action, factors responsible for the alarming phenomena of coastal erosion on the one hand and adverse environmental impacts and the high cost of 'hard' protection schemes, on the other, have created interest in the detailed examination of the potential and range of applicability of the emerging and promising category of 'soft' shore protection methods. 'Soft' methods such as beach nourishment, submerged breakwaters, artificial reefs, gravity drain systems, floating breakwaters, plantations of hydrophylous shrubs or even dry branches, applied mostly during the past 20 years, are recognised as possessing technical, environmental and financial advantageous properties deserving more attention and further developmental experimentation than has occured hitherto. On the other hand, 'hard' shore protection methods such as seawalls, groins and detached breakwaters, artefacts borrowed from port design and construction technology, no matter how well designed and well implemented they may be, can hardly avoid intensification of the consequential erosive, often devastating, effects on the down-drift shores. Moreover, they often do not constitute environmentally and financially attractive solutions for long stretches of eroding shoreline. Engineers and scientists practising design and implementation of shore defence schemes have been aware for many years of the public demand for improved shore protection technologies. They are encouraging efforts that promise enrichment of those environmentally sound and financially attractive methods that can be safely applied.




Beach Nourishment and Protection


Book Description

Many coastal communities have built structures at their beaches and added quantities of sand in contoured designs to combat erosion. Are such beach nourishment projects technically and economically sound? Or are they nothing more than building sand castles, as critics claim? Beach Nourishment and Protection provides a sound technical basis for decision-making, with recommendations regarding the utility of beach nourishment, the appropriate role of federal agencies, responsibility for cost, design methodology, and other issues. This volume: Examines the economic and social role of beaches, the history of beach nourishment projects, and management strategies for shore protection. Discusses the role of the U.S. Army Corps of Engineers and other federal agencies, with a close-up look at the federal flood insurance program. Explores the state of the art in project design and prediction of outcomes, including the controversy over the use of traditional and nontraditional shore protection devices. Addresses what is known about the environmental impacts of beach nourishment. Identifies what outcomes should be targeted for continued monitoring by project officials. Beach Nourishment and Protection provides insight into the technical, economic, environmental, and policy implications of beach nourishment and protection, with examples and suggested research directions.
