Expanding a port, deepening a navigation channel or creating new land for development, introduces changes to our physical, social, economic and political environment. Changes may result from events during the construction process, or relate to the nature of the completed structure. Changes can be positive or negative, short-term or long-term, and may affect the immediate vicinity of the project or a larger geographical area. Predicting and assessing all possible effects of a planned dredging activity in a scientifically-sound and reliable manner is essential, so that appropriate control measures can be taken to avoid or mitigate unwelcome impacts. This book provides guidance for a complete holistic environmental evaluation procedure and for the design and implementation of environmental control measures. The book is of particular interest to engineers, government agencies and port authorities, as well as civil engineering consultants and contractors involved in planning and designing dredging, maritime infrastructure and fluvial projects.

Included is the work of a team of more than 45 professional experimentalists, who explore innovative approaches to the vast array of experiments of differing complexity encountered by today's hydraulic engineer, from laboratory to field, from simple but well-conceived to complex and well-instrumented. The style of this book is intentionally succinct, making frequent use of convenient summaries, tables and examples to present information. All researchers, practitioners, and students conducting or evaluating experiments in hydraulics will find this book useful.

This two-volume book is a comprehensive guide to designing, conducting and interpreting experiments in a broad range of topics associated with hydraulic engineering. It is the first substantial effort in hydraulic engineering to assemble in one place descriptions of all the components of experimentation along with a concise outline of essential theory to highlight the intrinsic connection between analytical and experimental research and illustrate the need for their complementary use. Providing end-to-end guidance to support experimentalists is long overdue, as most of the information can only be found in scientific papers or specialized monographs on laboratory and fieldwork practice. The book was prepared for college faculty, researchers, practitioners, and students involved in hydraulics experiments. Written by a team of more than 45 authors well-experienced in hydraulics experimentation, the book takes into account experiments performed under a range of conditions, including well-equipped and -staffed laboratories, and laboratories lacking aspects of advanced instrumentation and expertise. The book could serve as a textbook on hydraulics experiments. Its style is intentionally concise and makes frequent use of convenient summaries, tables and figures to present information. The writers provide specific guidance on methods and instruments currently used in hydraulics experiments, and emphasizes new and emerging measurement technologies and analysis methods. Extensive references enable interested readers to further explore details on each topic.

The latest cutting-edge research on flood pulsing and wetland restoration in North America

Presenting the latest research from leaders in the field of restoration ecology, Flood Pulsing in Wetlands reflects the current movement to incorporate flood pulsing into wetland restoration efforts. Emphasizing how integral flood pulsing is to successful wetland restoration, the book’s contributors provide descriptions of restoration projects across North America in which flood pulsing has been primarily used to restore beneficial hydrodynamic conditions to floodplain areas, and improve or save vegetation, wildlife, and terrain.

Detailing the importance and applicability of recreating flood-pulsed conditions on floodplains for successful restoration, the first chapter introduces the concept of flood pulse and its unique role in wetland restoration. The following chapters detail the strategies and results of individual projects and the impact flood pulsing had on the projects’ overall goals. Case studies detail the history of each region, such as the Southwest, including the Sonoran Desert communities and the Middle Rio Grande; the Missouri River in Montana; the Illinois River Valley; and the Southeast, including Brushy Lake, Arkansas. Also documented is the most famous case of flood pulsing used in the restoration of an entire landscape, the Kissimmee River project. Approaches used to restore specific plant and animal populations, the unique ecological concerns of each region, and the future outlook for each area are fully described.

Extensive bibliographies for each chapter make Flood Pulsing in Wetlands: Restoring the Natural Hydrological Balance the essential reference for restoration ecologists, consultants in wetland restoration, government and restoration agency employees, land managers, ecologists, foresters, and geologists.

Attempting to extend the boundaries of land reclamation, this publication is a collection of conference papers addressing a range of topics from the practical challenges of cleaning up the most conaminated sites to the creation of new landscapes and the ethical issues surrounding land restoration.

Green Stormwater Infrastructure Fundamentals and Design Discover novel stormwater control measures to make for a greener tomorrow! The protection of our aquatic resources is growing in importance as the effects of climate change and continued urbanization are felt throughout the world. While most rain that falls onto vegetated spaces infiltrates the soil, rain that falls onto impervious surfaces will not, increasing downstream flooding and erosion and causing impaired water quality. Impervious surfaces such as road infrastructure, rooftops, and parking areas all increase runoff and mobilize many pollutants that have deposited on these surfaces that are then carried into our waterways. Proper management of this stormwater through green infrastructure is essential to address these challenges and reduce the environmental and ecological impacts brought about by this runoff. This book brings into focus resilient stormwater control measures (SCMs) for the reduction of stormwater flows and associated pollutants that can detrimentally impact our local environmental and ecological systems. These interventions are green infrastructure based, utilizing natural hydrologic and environmental features using soil and vegetation to manage stormwater. These technologies include water harvesting, bioretention and bioinfiltration, vegetated swales and filter strips, permeable pavements, sand filters, green roofs, and stormwater wetlands, among others. The basic science and engineering of these technologies is discussed, including performance information and best maintenance practices. Green Stormwater Infrastructure readers will also find: Research-informed resilient SCM design fundamentals Diagrams developed by the authors to enhance understanding Case studies to illustrate the points elucidated in the book End-of-chapter problems with a separate solutions manual Green Stormwater Infrastructure is an ideal resource for environmental, civil, and biological engineers and environmental scientists in the consulting field. Landscape architects, managers and engineers of watershed districts, and members of federal, state, and local governmental agencies--especially those in the departments of environmental protection and transportation--will find many uses for this guidebook. It will also be of interest to professors, upper-level undergraduates and graduate students in environmental, civil, and biological engineering programs.

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.

This book covers the basics of the hydrodynamics and vibration of structures subjected to environmental loads. It describes the interaction of hydrodynamics with the associated vibration of structures, giving simple explanations. Emphasis is placed on the applications of the theory to practical problems. Several case studies are provided to show how the theory outlined in the book is applied in the design of structures. Background material needed for understanding fluid-induced vibrations of structures is given to make the book reasonably self-sufficient. Examples are taken mainly from the novel structures that are of interest today, including ocean and offshore structures and components.Besides being a text for undergraduates, this book can serve as a handy reference for design engineers and consultants involved in the design of structures subjected to dynamics and vibration.

This book treats the subject of local scour around different kinds of marine structures, exposed to waves and/or currents. The first, major part of the book is devoted to marine pipelines, describing in detail all kinds of scour scenarios, and also making recommendations for scour protection. Other kinds of structures considered are single piles (slender or large), groups of piles, complex subsea structures, breakwaters, and seawalls. The scour due to ship propellers is also described. The book deals mainly with the scour in noncohesive sediment but, whenever possible, available literature on the scour in finer sediment has been incorporated. In addition, a chapter on the impact of wave-induced liquefaction is included.The authors' aim is to describe in detail the hydrodynamic processes causing the erosion. With a hydrodynamic understanding, it is easier for the consulting engineer to predict scour in those many cases where physical model tests are not available.

Stepped channel designs have been used for more than 3,500 years. A significant number of dams were built with overflow stepped spillways during the nineteenth and early twentieth centuries, before the design technique became outdated with the progresses in hydraulic jump stilling basin design. Recent advances in technology (e.g. RCC, polymer-coated gabion wire) have triggered a regain in interest for the stepped design, although much expertise had been lost in the last eighty years. The steps increase significantly the rate of energy dissipation taking place along the chute and reduce the size of the required downstream energy dissipation basin. Stepped cascades are used also in water treatment plants to enhance the air-water transfer of atmospheric gases (e.g. oxygen, nitrogen) and of volatile organic components (VOC). This book presents the state-of-the-art in stepped channel hydraulics. It is based upon the research expertise of the writer, his professional experience as an expert-consultant, and his experience in teaching stepped spillway hydraulics to undergraduate students, postgraduate research students and professionals since 1982. Results from more than forty-five laboratory studies and four prototype investigations were reanalyzed and compared, enabling the book to provide a new understanding of stepped channel hydraulics, aimed at both the research and professional communities.

This book delivers a wealth of information on changes in flood risk in Europe, and considers causes for change. The temporal coverage is mostly focused on post-1900 events, reflecting the typical availability of data, but some information on earlier flood events is also included.

The power sector has undergone a liberalization process both in industrialized and developing countries, involving market regimes, as well as ownership structure. These processes have called for new and innovative concepts, affecting both the operation of existing hydropower plants and transmission facilities, as well as the development and implementation of new projects. At the same time a sharper focus is being placed on environmental considerations. In this context it is important to emphasize the obvious benefits of hydropower as a clean, renewable and sustainable energy source. It is however also relevant to focus on the impact on the local environment during the planning and operation of hydropower plants. New knowledge and methods have been developed that make it possible to mitigate the local undesirable effects of such projects. Development and operation of modern power systems require sophisticated technology. Continuous research and development in this field is therefore crucial to maintaining hydropower as a competitive and environmentally well-accepted form of power generation.

Among development assistance agencies, the World Bank has led the way in policies to mitigate the impact of large-scale engineering projects on local populations, particularly in the building of dams. Since the 1980s the Bank has implemented guidelines for policies with respect to displacement, social infrastructure and services, environmental effects, resettlement, compensation, and the restoration of income for those affected. Having learned from the failures of past resettlement programs, the Bank has endeavored to function as a responsible and caring agency. This volume builds upon earlier studies and field work to offer a broad look at dam-building projects in six countries and to review the outcomes of Bank policy, learn from experience, and assess outside criticism.
The book covers representative dam projects in India, Thailand, Togo, China, Indonesia, and Brazil. Each project was undertaken after Bank resettlement guidelines had been implemented. The widely ranging results in each country are assessed. In the areas of compensation for acquired land, relocation, infrastructure and services, the contributors note satisfactory levels of improvement or positive trends. Governments are moving towards acceptance of the idea that displaced families should be paid the real value of their lost assets. Relocation processes are now keeping pace with water movement caused by dam building, and health, education, utilities, and roads are better than before the resettlement.
Other results have been less positive. The impact on incomes of those involuntarily resettled has been harsh in some locations. Resettler dissatisfaction has been intense, notably in those countries where the national economies are not experiencing strong growth. The Bank's performance itself has been uneven. There have been lapses in appraisal and monitoring during the projects and insufficient follow-through support for resettlement operations after the completion of loan and credit disbursements.
In addition to its case by case analysis of countries and projects, the book includes detailed lessons and recommendations to strengthen resettlement policy and practice. Involuntary Resettlement will be of interest to economists, sociologists, and professionals working in regional development policy.

By the year 2000, the world had built more than 45,000 large dams to irrigate crops, generate power, control floods in wet times and store water in dry times. Yet, in the last century, large dams also disrupted the ecology of half the world's rivers, displaced tens of millions of people from their homes and left nations burdened with debt. Their impacts have inevitably generated growing controversy and conflicts. Resolving their role in meeting water and energy needs is vital for the future and illustrates the complex development challenges that face our societies. The Report of the World Commission on Dams: - is the product of an unprecedented global public policy effort to bring governments, the private sector and civil society together in one process - provides the first comprehensive global and independent review of the performance and impacts of dams - presents a new framework for water and energy resources development - develops an agenda of seven strategic priorities with corresponding criteria and guidelines for future decision-making. Challenging our assumptions, the Commission sets before us the hard, rigorous and clear-eyed evidence of exactly why nations decide to build dams and how dams can affect human, plant and animal life, for better or for worse. Dams and Development: A New Framework for Decision-Making is vital reading on the future of dams as well as the changing development context where new voices, choices and options leave little room for a business-as-usual scenario.
