Managing Urban Stormwater Systems

This is the West African contribution to a series of regional studies, some twenty years in the making, on the history of irrigation, commissioned by the International Commission on Irrigation and Drainage. It demonstrates that although Nigeria did not produce such old and elaborate hydralic structures as those in the Nile and Euphrates-Tigris valleys, its people nevertheless devised systems of irrigation and flood control early on in their history. It further shows that the history of agricultural development is inseparable from the social history of the people. Contents: pre-colonial period to 1900; colonial period 1900-1906; Kware irrigation scheme 1925-1963; irrigation development besides Kware 1925-1959; irrigation development 1960-1999; evolution of the federal ministry of water resources and irrigation administration in Nigeria; concept and evolution of river basin development; floods and droughts in Nigeria; drainage of agricultural lands; irrigation research, extension and training; land tenure, water laws, rights and customs; international organisations, treaties and agreements; and current problems of irrigation, drainage and flood controls in Nigeria.

The Elkhorn River originates in north-central Nebraska and empties into the Platte River just west of Omaha. One of the first written records of the Elkhorn describes a flood. A flood hindered travel up the river by the valley's first non-Indian settlers. Decade after decade, floods have swept away mill dams, destroyed crops, drowned stock, soaked inventories, filled basements, undercut roads, washed out railroads and bridges, turned unfortunate riverside homesaEURO"even a dance hallaEURO"into unwieldy watercraft, and killed people. Everyone in the Elkhorn Valley agreed the Flood of 1944 was the worst in history. Until the deadly Flood of 2010 took the title. From a perspective unusual on the Great PlainsaEURO"the problem of too much wateraEURO" Flood on the Tracks offers an intimate portrait of life in the Elkhorn River Basin of northeast Nebraska. In a region often defined by aridity, rivers and their basins have provided sustenance, shelter, fertile soil, and overland highways. In many ways Plains rivers organize human lives. When they overflow, which they can be counted on to do, they disorganize them. Using Plains Indian winter counts, postcards, photographs, newspaper accounts, government records, and more, Flood on the Tracks chronicles the river's natural and human history from the Plains Indians into the twenty-first century. The Elkhorn's floods show us how the nature of disaster has changed and how Plainsfolk liveaEURO"and dieaEURO"with a river.

Where will the water come from to sustain the great desert cities of Las Vegas, Los Angeles, and Phoenix? In a provocative exploration of the past, present, and future of water in the West, James Lawrence Powell begins at Lake Powell, the vast reservoir that has become an emblem of this story. At present, Lake Powell is less than half full. Bathtub rings ten stories tall encircle its blue water; boat ramps and marinas lie stranded and useless. To refill it would require surplus water - but there is no surplus: burgeoning populations and thirsty crops consume every drop of the Colorado River. Add to this picture the looming effects of global warming and drought, and the scenario becomes bleaker still. "Dead Pool", featuring rarely seen historical photographs, explains why America built the dam that made Lake Powell and others like it and then allowed its citizens to become dependent on their benefits, which were always temporary. Writing for a wide audience, Powell shows us exactly why an urgent threat during the first half of the twenty-first century will come, not from the rising of the seas but from the falling of the reservoirs.

When it is completed in 2009 the Three Gorges Dam, a hydroelectric dam which spans the Yangzi River in China, will generate enough electricity to power four cities the size of Los Angeles. Despite the fact that it will drastically reduce coal consumption and eliminate 100 million tons of greenhouse gas emissions per year, the project is entwined in controversy. Since construction began in 1994, nearly one thousand neighboring towns and villages have been submerged and over one million people have been displaced by the dam's 375-mile reservoir.
With "Displacement," the University of Chicago's Smart Museum of Art extends a series of exhibition catalogs produced in conjunction with renowned Chinese art scholar and curator Wu Hung. This fascinating project reveals how four leading Chinese artists--Chen Qiulin, Liu Xiaodong, Yun-Fei Ji, and Zhuang Hui--have confronted the Three Gorges Dam, employing a variety of contemporary techniques to respond to the massive forced migration of people, the demolition of ancient architecture, and the devastation of the local landscape.
Alongside the catalog's lavish illustrations are three essays, penned by Wu Hung, Stephanie Smith, and Jason McGrath, which range in topic from contemporary art and environmental sustainability to Chinese film and its treatment of the dam. In addition, interviews conducted with each of the artists offer insight into their work and address the difficult task of relating artistic practice to the wider world.

Erosion is the most common cause of failures at earth-dams, dikes and levees, whether through overtopping and overflowing, or internal erosion and piping. This book is dedicated to the phenomenon of internal erosion and piping. It is not intended to be exhaustive on the subject, but brings together some of the latest international research and advances. Emphasis is placed on physical processes, how they can be studied in the laboratory, and how test results can be applied to levees and dams. The results from several research projects in Australia, France, the Netherlands and the United States are covered by the authors. Our aim has been to share our most recent findings with students, researchers and practitioners. Understanding the failure of an earth-dam or a levee by erosion in a unified framework, whether internal erosion or surface erosion, requires continuous research in this field. We hope that the reader will gain knowledge from this book that leads to further progress in the challenging field of the safety of levees and dams.

About the Authors

Stephane Bonelli is a Research Professor at Irstea (French Environmental Sciences and Technologies Research Institute) in Aix-en-Provence, France. He has over 20 years of teaching and research experience, and has been a member of the ICOLD (International Commission on Large Dams) European Working Group on Internal Erosion since 2005. He has participated in 19 large dam reviews in France (visual inspection, monitoring data analysis and numerical modeling). His current activities include research, teaching and consultancy, focusing on soil erosion and the processes of levee breach.

This book describes the practical aspects necessary to design, manage, monitor, and assess these hydraulic structures. The approaches, used to develop tools and methods for assessing performance and safety of dams largely applied for French cases, has been discussed for aggregating heterogeneous information and expert knowledge. Field measurements have been applied to the performance and the safety assessment for two real-life examples of old dams: Zermanice Concrete Dam and Sance Rockfill Dam in the Czech Republic. The finite element models (FEM), to simulate the crucial loading and monitoring stages of these dams, indicate heave, tilting, uneven displacements, and large settlements. Dam safety and risk management have been performed through the design of spillways, energy dissipators, dams' aseismic air-cushion control, simulation of aseismic mechanisms, control optimisation using shaking table tests, and the opportunity to use optic fibre crack sensing to prevent seismic damage.

Hydraulic fracturing is a technique used to free oil and natural gas trapped underground in low-permeability rock formations by injecting a fluid under high pressure in order to crack the formations. The composition of a fracturing fluid varies with the nature of the formation, but typically contains mostly water; a proppant to keep the fractures open, such as sand; and a small percentage of chemical additives. Some of these additives may be hazardous to health and the environment. The Shale Gas Production Subcommittee of the Secretary of Energy Advisory Board (SEAB) has recommended public disclosure, on a well-by-well basis, of all the chemical ingredients added to fracturing fluids, with some protection for trade secrets. This book provides an overview of current and proposed laws and regulations at the state and federal levels that require the disclosure of the chemicals added to the fluid used in hydraulic fracturing.

Hydraulic engineering of dams and their appurtenant structures counts among the essential tasks to successfully design safe water-retaining reservoirs for hydroelectric power generation, flood retention, and irrigation and water supply demands. In view of climate change, especially dams and reservoirs, among other water infrastructure, will and have to play an even more important role than in the past as part of necessary mitigation and adaptation measures to satisfy vital needs in water supply, renewable energy and food worldwide as expressed in the Sustainable Development Goals of the United Nations. This book deals with the major hydraulic aspects of dam engineering considering recent developments in research and construction, namely overflow, conveyance and dissipations structures of spillways, river diversion facilities during construction, bottom and low-level outlets as well as intake structures. Furthermore, the book covers reservoir sedimentation, impulse waves and dambreak waves, which are relevant topics in view of sustainable and safe operation of reservoirs. The book is richly illustrated with photographs, highlighting the various appurtenant structures of dams addressed in the book chapters, as well as figures and diagrams showing important relations among the governing parameters of a certain phenomenon. An extensive literature review along with an updated bibliography complete this book.

This book is based on the author's 49 years of experience as a practicing coastal engineer and 34 years as professor of coastal engineering and management at Queen's University. The book is therefore thoroughly practical in nature, but it also reflects newly relevant issues, such as consequences of failure, impacts of rising sea levels, aging infrastructure, real estate development, and contemporary decision making, design and education.This textbook is useful for undergraduate students, postgraduate students and practicing engineers. It covers waves, structures, sediment movement, coastal management, and contemporary coastal design and decision making. It presents both basic principles and engineering solutions. It discusses the traditional methods of analysis and synthesis (design), but also contemporary design methodologies, such as working with environmental impacts.The second edition expanded greatly on the topics of failure and resilience that surfaced as a result of recent disasters from hurricane surges and tsunamis. It updated the discussion of design and decision making for the 21st century, with many new examples.This third edition develops some of these topics further, but its largest new changes is the chapter on climate change. This chapter presents the basics of climate change and then goes on to stress the practical implications of the impacts of climate change, focusing on what is of importance to coastal and fluvial specialists.

The Bureau of Reclamation is responsible for the construction of most of the large irrigation and water resources infrastructure in the West. Reclamation manages water resource facilities in 17 western states with an original development cost of over $20.0 billion. Furthermore, Reclamation is over 100 years old. This ageing infrastructure requires increased maintenance and replacement efforts and expenditures. This book describes Reclamation's approach to managing ageing infrastructure. There is also a discussion of four specific approaches to managing Reclamation's ageing infrastructure through legislative action. Furthermore, the principal federal program to aid municipal wastewater treatment plant construction is authorised in the Clean Water Act (CWA). This book explores the funding for EPA wastewater assistance and some of the funded projects which are not authorised in the Clean Water Act nor the Safe Drinking Water Act. This book also examines the urgent actions needed to be taken for additional funding to resolve any deficiencies in dams. While dams have multiple benefits, they can also present a risk to public safety and economic infrastructure. This book consists of public documents which have been located, gathered, combined, reformatted, and enhanced with a subject index, selectively edited and bound to provide easy access.

Responsibility for flood risk management in the United States is a shared responsibility between multiple Federal, State, and local government agencies with a complex set of programs and authorities. Nationally, both the US Army Corps of Engineers (USACE) and the Federal Emergency Management Agency (FEMA) have programs to assist states and communities in reducing flood damages and promoting sound flood risk management. The authority to determine how land is used in floodplains and to enforce flood-wise requirements is entirely the responsibility of state and local government. Floodplain management choices made by state and local officials, in turn, impact the effectiveness of federal programs to mitigate flood risk and the performance of federal flood damage reduction infrastructure. One key challenge is to ensure that as the public and government leaders make flood risk management decisions, they integrate environmental, social, and economic factors and consider all available tools to improve public safety. Importantly, the public must be educated both as to the risks they face and actions they can take to reduce their risks. Because of this complex arrangement of responsibilities, only a life-cycle, comprehensive and collaborative systems approach will enable communities to sustain an effective reduction of risks from flooding.

Each year, floods cause an enormous amount of global economic and social damage, impacting transportation systems, water supplies, agriculture, and health. Response management to catastrophic floods require increased measures involving integrated planning, adaptation, and recovery strategies in order to protect against human loss. Decision Support Methods for Assessing Flood Risk and Vulnerability is a pivotal reference source that provides vital research on the application of effective models and tools focused on the diagnosis of vulnerability to flooding risks and evaluates and measures the impact of floods on socio-economic wellbeing. While highlighting topics such as hydrological events, soil erosion, and flood vulnerability, this publication explores methods of identifying appropriate adaptation strategies. This book is ideally designed for researchers, students, academicians, policymakers, government officials, and technology developers seeking current empirical research findings to be used to improve the overall understanding of the flood phenomenon.
