First published in 1987 and named a Choice Outstanding Academic Book the following year, Damming the Delaware is the definitive study of two hundred years of water management history along the Delaware River. The history of the Tocks Island Dam Project is traced from an early 1783 anti-dam treaty, through the highly emotional environmental controversy in the 1970s, to the historic Good Faith agreement of the 1980s. The story involves the water politics of four states, two major U.S. cities, and the federal government, plus the influence of the environmental movement over major public works projects.

In this second edition, the author updates the Tocks Island/Delaware River story to 2005. A major shift in the underlying philosophies of Delaware River management during the intervening years is described along with various successes and failures in water management. A Foreword to the second edition is written by Maya van Rossum, the Delaware Riverkeeper and Executive Director of the Delaware Riverkeeper Network, a nonprofit environmental advocacy organization that has both successfully fought dam projects and removed existing dams.

Louisiana's coastal wetlands represent a significant natural and economic resource for the state and the nation but have been disappearing at a rate of 25 to 35 square miles each year. In the past 50 years, more than 1,500 square miles have been lost. The wetlands contain 95 per cent of all marine species in the Gulf of Mexico, 30 per cent of the nation's fisheries, one of the largest habitats in the world for migratory waterfowl, and more than 25 per cent of all oil and gas used in the United States originates or pass through there. They also serve as a buffer for hurricanes. The state of Louisiana asked the American Society of Civil Engineers (ASCE) to convene a summit to discuss technical aspects involved in carrying out restoration programs, and to report on the insights that could be drawn from the summit. This report of the ASCE Task Committee on America's Wetland provides conclusions and recommendations concerning the technical topics discussed at the summit, as well as the Task Committee's recommendations for a path forward.

H2GEO: Geotechnical Engineering for Water Resources presents practical case studies and project results for geotechnical engineering on a variety of water resources projects located in Colorado and the Western United States. Practicing geotechnical engineers, engineering geologists, and hydrologists share their unique project solutions and real-world experiences with actual projects, including Colorado's oldest water resources project, new and modified dams, pipelines, tunnels, flood hydrology, flood control, ground-water supply and wells, and surface reservoirs. The seventeen papers in this collection were presented at the 2004 Biennial Geotechnical Seminar in Denver, Colorado. Many of the papers in this ""Geotechnical Practical Publication"" deal with dams. These include the 1000-year-old reservoirs used by the Ancestral Puebloans at Mesa Verde. Other dam papers discuss new mountain dams and the expansion or repair of existing dams. Flood hydrology papers present the results of erosion control projects in areas scarred by wildfires, flood control in urban areas with intermittent streams, and riverbank slope stability. The underground papers deal with water tunnel rehabilitation, mine site cleanup, deep shaft modeling, and dam conduit repair. The last group of papers examines shallow and deep groundwater wells, as well as reservoirs built in alluvium and hard bedrock. All of the papers discuss actual projects with practical applications of geotechnical engineering innovation.

Advances in Coastal Structure Design presents a compendium of 10 papers addressing the state-of-the-art advances in Coastal Structure Design by internationally renowned authors. The papers focus on the tools and techniques used to analyze coastal processes and design engineering solutions to them. The first three chapters present multiple view points and policies regarding how the coastal-structure debate in the United States came to be and how policies are evolving to handle issues concerning the interactions of structures with shorelines. This work includes a paper on the global perspective surrounding the policy, design, construction and monitoring of coastal structures and the third demonstrating how a good knowledge of multi-disciplinary areas of geotechnical, geologic, and seismic conditions are essential to successful planning and design of coastal structures. The following chapter discusses a key aspect of coastal structure design, which is modeling. The remaining papers present insightful information on: wave distributions and probabilities; an overview of breakwater design and construction since the 18th century; and advances in structural design aspects on performance-based design. The final chapter demonstrates how sand, vegetation, cobbles, and small structures can be effectively utilized to provide coastal protection. Contents include: Coastal Structure Debate: Public and Policy Aspects; International Perspectives on Coastal Structure Uses; Geotechnical Consideration for Coastal Structure Design; Numerical Modeling as a Design Tool for Coastal Structures; Physical Modeling Considerations for Coastal Structures; Selection of a Design Wave Height for Coastal Engineering; Historical Overview of Rubble Mound Structure Design and Construction; Advances in Breakwater and Revetment Design; Design Aspects of Groins and Jetties; Application of Coastal Engineering in Coastal Zone Management.

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 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 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.

This verification report describes a field evaluation of the installation of a silt fence using the Tommy Silt Fence Static Slicing Method and compares this method to traditional trenching methods. The slicing method has been used extensively over the past few years, but has not undergone a true field application test by a third party. State Departments of Transportation and federal, state, and local environmental regulatory agencies have expressed a desire and, in some cases, a need, for baseline environmental data providing a general picture of performance and feasibility of the Tommy Slicing Method for silt fence installation and erosion control.

A clear, up-to-date presentation of the principles of flow in open channels

A fundamental knowledge of flow in open channels is essential for the planning and design of systems to manage water resources. Open-Channel Flow conveys this knowledge through the use of practical problems that can be solved either analytically or by simple numerical methods that do not require the use of computer software.

This completely up-to-date text includes several features not found in any other book on the subject. It derives one- dimensional equations of motion using both a simplified approach and a rigorous approach, and it explains the distinction between the momentum and mechanical energy equations. The author places great emphasis on identifying the types and locations of the control sections that are essential in analyzing flow profiles, and he includes a section on recently recognized nonunique flow profiles.

Offering numerous worked examples that are helpful in understanding the basic principles and their practical applications, this book:

• Presents the latest computational methods for profiling spatially varied and unsteady flow
• Includes end-of-section exercises that measure and build understanding
• Fully explains governing equations in algebraic and differential form
• Brings sluice-gate analysis completely up to date
• Covers artificial channel controls such as weirs, spillways, and gates, and special topics such as transitions in supercritical flow and flow through culverts

Written in metric units throughout, this excellent learning tool for senior- and graduate-level students in civil and environmental engineering programs is also a useful reference for practicing civil and environmental engineers.

Imported water has transformed the Golden State's environment and quality of life. In the last one hundred years, land ownership patterns and real estate boosterism have dramatically altered both urban and rural communities across the entire state. The key has been water from the Eastern Sierra, the Colorado River and, finally, Northern California rivers. Whoever brings the water, brings the people wrote engineer William Mulholland, whose leadership began the process of water irrigating unlimited growth. Using first-person voices of Californians to reveal the resulting changes, Carle concludes that the new millennium may be the time to stop drowning the California dream.

With extensive use of oral histories, contemporary newspaper articles, and autobiographies, Carle provides a rich exploration of the historic change in California, showing that imported water has shaped the pattern of population growth in the state. Water choices remain the primary tool, he claims, for shaping California's future. The state's damaged environment and reduced quality of life can be corrected if Californians will step out of their historic pattern and embrace limited water supplies as a fact of life in this naturally dry region.

"Of late historians have become increasingly interested in the vast re-ordering of the environment involved in the creation of America. Nowhere was this more true than in the Sacramento Valley where re-ordering edged into folly. "Battling the Inland Sea is a powerful evocation of the losses and gains involved in battling the mighty Sacramento River. But more than this, it is an exploration of the national will as it sought to rearrange nature herself with such mixed results. Here is history dealing with the most elemental forces of land, water and engineering as they are shaped by public policy. Here is the profound drama of value and symbol which occurs when Americans come into conflict with forces over which they can exercise, as Robert Kelley shows, only the most transitory and pyrrhic victories."--Kevin Starr, author of the "Americans and the California Dream

"Robert Kelley's research into the origins of California's first great flood control system has already helped to inform the shaping of the state's water laws. Now he opens up the benefits of that work for the average reader in a wonderfully clear and engaging story that manages, among other things, to show that water development in the United States hasn't been just a matter of engineering but a cultural and intellectual achievement as well."--William Kahrl, author of "Water and Power

"A vividly written narrative of one of the major transformations of the physical world we inhabit. Robert Kelley draws upon his rich store of learning and insight to set the struggles over the Sacramento Valley into a broad context. His book contains important lessons for those who would understand the American economy, environment, politics,or culture."--Daniel W. Howe, author of "The Political Culture of the American Whigs

This book discusses coastal defense measures, which have not improved in the past few decades, and better alternatives. It emphasizes on the existence of stable bays in coastal geomorphology and their use in coastal stabilization. The conventional measures for saving beaches, such as seawalls, groins, offshore breakwaters, and renourishment, are discussed in detail, followed by an alternative known as headland control. Many types of coast, and the respective defense measures, are discussed, especially for eroding beaches downcoast of harbors with long breakwaters. The formation of offshore bars during storms is examined and the design of stable recreational beaches is demonstrated. Practical design problems are discussed in all cases. Many issues requiring attention in coastal engineering are also outlined.

Contaminated land and the methods and legal controls governing its reclamation for subsequent development and use are of great current interest and concern. This volume in the Issues in Environmental Science and Technology series contains seven articles which treat the many aspects of this subject, ranging from risk assessment and risk management, through specific remediation methods and the evolution of government policy and controls, to analysis of the legal and technical features of specific environmental insurance policies. The chemistry of the non-ferrous heavy metals lead, zinc and cadmium is examined in relation to reclamation of superfund sites in the USA alongside a consideration of the role of the Welsh Development Agency in developing strategies for the recovery of derelict and contaminated land. An authoritative treatment of each of the topics is ensured by the particular expertise and distinction of the authors, and as such Contaminated Land and Its Reclamation will make an important contribution to the public debate on these issues. It will be essential reading for all those groups of people directly or indirectly involved, from consultants and their technical advisors, through developers, contractors and landowners, to local authorities and government agencies with responsibility for policy and its implementation in this area.
