In past decades, urban water management practices focused on optimizing the design and operation of water distribution networks, wastewater collection systems, and water and wastewater treatment plants. However, municipalities are now faced with aging urban water infrastructures whose operation must be improved and expanded to maintain current high standards of living as well as new challenges such as climate change, systems sustainability and water quality issues. Integrating the latest developments in urban water hydrology and management, Urban Water Engineering and Management takes a system approach to urban water hydrology, engineering, planning and management, supplying examples and case studies and highlighting pressing issues such as urban water governance, disaster management, and climate change impacts on urban areas. The book draws attention to climate change as a main concern of this century by focusing on its impact the components of water cycle.

The book covers modeling of urban water cycle components, urban water supply, and distribution systems demand forecasting. It also presents classical issues, such as design of water distribution networks and wastewater and storm collection in urban settings, from a system's perspective. The text also includes a discussion of water governance and disaster management in urban areas and the urbanization effects on the environment and the needed water infrastructure development in urban areas. Against this background, the authors discuss the importance of understanding the principles of simulation, optimization, multiple-criterion decision making, and conflict resolution for successful, integrated urban water management. They explore integrated water management and planning solutions for incorporating structural and nonstructural means to achieve the best operational schemes at affordable costs, going beyond using the existing structures and physical limitations on water availability to include technical, social, political, and economic aspects of better water and wastewater management in urban areas.

Written and designed especially for intermediate and advanced courses/modules in water resources in civil and environmental engineering, and in urban planning, the book can be used as a textbook for civil engineering, urban and regional planning, geography, environmental science, and in courses dealing with urban water cycle. It also introduces new horizons for engineers as well as policy and decision makers who plan for future urban water and regional sustainability. Engineers and planners, especially those who work on design, planning, and management of urban systems and/or community development, can use this book in practice because it deals with a broad range of real world urban water problems.

This book explores many recent techniques including ANN, fuzzy logic, hydraulic models and IWRM utilized for integrated water resources management, a real challenge in India for obtaining high irrigation efficiency. The book deals with topics of current interest, such as climate change, floods, drought, and hydrological extremes. The impact of climate change on water resources is drawing worldwide attention these days; for water resources, many countries are already stressed and climate change along with burgeoning population, rising standard of living, and increasing demand are adding to the stress. Further, river basins are becoming less resilient to climatic vagaries. Fundamental to addressing these issues is hydrological modelling which is covered in this book Further, integrated water resources management is vital to ensure water and food security. Integral to the management is groundwater and solute transport. The book encompasses tools that will be useful to mitigate the adverse consequences of natural disasters.

Humanity is deeply committed to living along the world's shores, but a catastrophic storm like Sandy - which took hundreds of lives and caused many billions of dollars in damages - shines a bright light at how costly and vulnerable life on a shoreline can be. Taking Chances offers a wide-ranging exploration of the diverse challenges of Sandy and asks if this massive event will really change how coastal living and development is managed. Bringing together leading researchers - including biologists, urban planners, utilities experts, and climatologists, among others - Taking Chances illuminates reactions to the dangers revealed by Sandy. Focusing on New Jersey, New York, and other hard-hit areas, the contributors explore whether Hurricane Sandy has indeed transformed our perceptions of coastal hazards, if we have made radically new plans in response to Sandy, and what we think should be done over the long run to improve coastal resilience. Surprisingly, one essay notes that while a large majority of New Jerseyans identified Sandy with climate change and favored carefully assessing the likelihood of damage from future storms before rebuilding the Shore, their political leaders quickly poured millions into reconstruction. Indeed, much here is disquieting. One contributor points out that investors scared off from further investments on the shore are quickly replaced by new investors, sustaining or increasing the overall human exposure to risk. Likewise, a study of the Gowanus Canal area of Brooklyn shows that, even after Sandy swamped the area with toxic flood waters, plans to convert abandoned industrial lots around the canal into high-density condominiums went on undeterred. By contrast, utilities, emergency officials, and others who routinely make long-term plans have changed operations in response to the storm, and provide examples of adaptation in the face of climate change. Will Sandy be a tipping point in coastal policy debates - or simply dismissed as a once-in-a-century anomaly? This thought-provoking collection of essays in Taking Chances makes an important contribution to this debate.

Hydraulic fracturing, commonly referred to as "fracking," is a technique used by the oil and gas industry to mine hydrocarbons trapped deep beneath the Earth's surface. The principles underlying the technology are not new. Fracking was first applied at the commercial level in the United States as early as 1947, and over the decades it has been applied in various countries including Canada, the UK, and Russia. The author worked with engineering teams as early as the mid-1970s in evaluating ways to improve oil recovery from this practice. By and large fracking was not an economically competitive process and had limited applications until the early 2000s. Several factors altered the importance of this technology, among them being significant technological innovations in drilling practices with impressive high tech tools for exploration, well construction and integrity, and recovery along with discoveries of massive natural gas reserves in the United States and other parts of the world. These factors have catapulted the application of the technology to what is best described as the gold rush of the 21st century, with exploration and natural gas plays proceeding at a pace that seemingly is unrivaled by any historical industrial endeavor. But this level of activity has invoked widespread criticism from concerned citizens and environmental groups in almost every nation across the Globe. This outstanding new volume offers the industry a handbook of environmental management practices that can mitigate risks to the environment and, through best practices and current technologies, to conform to the current standards and regulations that are in place to provide the world with the energy it needs while avoiding environmental damage. For the new hire, veteran engineer, and student alike, this is a one-of-a-kind volume, a must-have for anyone working in hydraulic fracturing.

This book shares essential insights on evaporites and their effects on dams and reservoirs. The intensity of the solution and suffusion process in evaporites (gypsum and salt) is much greater than the solution of carbonates, and evaporites are particularly vulnerable at dam and reservoir sites. Moreover, the presence of evaporites in the vicinity of dams or reservoirs often leads to serious problems: numerous dams in countries around the world (e.g. China, Germany, Iran, Iraq, Peru, Russia, Spain, the Unites States, and Venezuela) have been affected by evaporite dissolution problems. Several of these dams were seriously endangered or ultimately abandoned, even though the best available engineering prevention and remediation practices were applied. Conventional geotechnical methods based on treating the underground (e.g. grout curtains) or surface (e.g. protective blankets) were not successful. This book presents and analyzes revealing case studies in this regard. To improve geotechnical remediation in connection with preventing seepage from reservoirs situated in evaporites, particularly in gypsum, it puts forward a new chemical solution that, after painstaking laboratory testing, was successfully applied in the field.

In a time when threats against the maritime community have never been greater, Maritime Security: Protection of Marinas, Ports, Small Watercraft, Yachts, and Ships provides a single, comprehensive source of necessary information for understanding and preventing or reducing threats to the maritime community. The book defines what comprises the maritime community, including marinas, ports, small watercraft, yachts, and ships. It focuses on the protection of these rather than the protection of cargo in the maritime supply chain, since with the protection of the infrastructural elements it follows that the cargo is secured. In identifying and discussing threats to security, the book includes natural threats such as storms as well as traditional criminal threats and piracy, with especially detailed examinations of terrorism and cybersecurity. It also introduces the US Coast Guard America's Waterway Watch program, describing the components of the program, its implementation throughout the maritime community, and its successes. By dealing with the security of all areas within the maritime community, Maritime Security is highly valuable to all members of the community, from the local boater to professionals charged with the protection of major ports and seagoing vessels. It gives you the skills to understand, identify, analyze, and address natural and man-made threats to localized or broad sections in the maritime community.

This research is dedicated to studying longterm estuarine morphodynamic behavior under combined river and tidal forcing. Analysis of river tides in the Yangtze River estuary (YRE) in China, schematized morphodynamic modeling in 1D and 2D mode and morphodynamic modeling of the YRE based on a process-based numerical model (Delft3D) are conducted. Morphodynamic sensitivities to river discharge magnitude and time variations, tidal strength and tidal constituents are then systematically explored. Analysis of river tides in the YRE reveals strong river-tide interactions and non-linear modulation of tides by river discharge. River discharge alters tidal asymmetries and resultant tidal residual sediment transport. Analysis of morphodynamic modeling results exposes significant mechanisms inducing tidal residual sediment transport and controlling long-term morphodynamic development. Morphodynamic equilibria in 1D and 2D simulations can be defined by vanishing gradients of tidal residual sediment transports and meeting empirical morphodynamic relationships. This research indicates the value of numerical modeling in examining long-term morphodynamic development in millennia time scale. Understanding of the controls on morphodynamic behavior in estuaries under river and tidal forcing is to the benefit of managing estuaries' functions in a long-term point of view.

The ability to predict the movement of cohesive sedmient within coastal, estaurine or inland waters has a significant economical and ecological importance in the development of new engineering works and the maintenance of existing installations.

The knowledge section presents data intended to show the practising engineer which parameters are important in each of the above processes. The procedure section gives practical methods for estimating the rates of erosion, transport, deposition and consolidation of the site conditions.

This book proposes a methodology for the identification of flooding in urban areas, by the denomination of 1) urban hydrographic basin; and 2) polygon of flood risk. This work will enable readers to elaborate a preventive program in Latin America and analogous regions. The authorities could use it as a basis to create urban planning strategies or preventive programs to reduce or eliminate the flooding hazard. The growth of an urban area implies that the natural terrain is covered by an asphalt folder, which results in an Urban Hydrographic Basin where rainwater drains down its streets filtering through sewers towards rainwater drains or wastewater. Initially, the drainages are calculated according to the population in a specific urban area, however, the population growth causes the growth of the urban area, where the old drainages and new roads are linked, causing their saturation and chaos. More water runs down the streets and is accumulated in the lower areas, causing flooding.

In the wake of Hurricane Katrina and the flooding of New Orleans in 2005, this interdisciplinary book brings together five years of empirical research funded by the National Science Foundation. It explores the causes of flooding in the United States and the ways in which local communities can reduce the associated human casualties and property damage. Focussing on Texas and Florida, the authors investigate factors other than rainfall that determine the degree of flooding, and consider the key role of non-structural techniques and strategies in flood mitigation. The authors present an empirical and multi-scale assessment that underlines the critical importance of local planning and development decisions. Written for advanced students and researchers in hazard mitigation, hydrology, geography, environmental planning and public policy, this book will also provide policy makers, government employees and engineers with important insights into how to make their communities more resilient to the adverse impacts of flooding.

A respected hydraulic engineer, William Henry Wheeler (1832-1915) established himself as an authority in the fields of low-lying land reclamation and drainage, embanking, and the improvement of tidal rivers and harbours. Based on articles written for The Engineer in 1887, he published this more substantial work in 1888 to provide a practical point of reference for those working on existing drainage systems or designing and implementing new schemes. Drawing on first-hand knowledge of the low-lying fens of England and the polders of Holland, Wheeler describes the processes of drainage by gravitation and steam power. The book also includes chapters on lifting and draining water using the scoop wheel, the Archimedean screw pump and the centrifugal pump. Providing also a wealth of operational facts relating to pumping stations in England and abroad, this remains a rich source of information for those interested in the history of civil engineering.

One of the leading figures in the age of great engineers, David Stevenson (1815 86) was the son of a lighthouse builder, and while studying at Edinburgh University he was already gaining experience at his father's side. It is for his lighthouses and works of inland navigation that he is best remembered: he designed Britain's most northerly lighthouse and worked on improving navigation on rivers such as the Dee, the Forth and the Clyde. His article on inland navigation for the Encyclopaedia Britannica was published separately in 1858, and was revised and updated for this second edition in 1872. Although Stevenson acknowledges that the age of the canal has been superseded by the age of the railway, he maintains that there is much to learn from the older technology. Illustrated with cross-sections and plans, this work will be of interest to readers seeking to explore the history of Britain's industrial infrastructure.

Dynamic programming is a method of solving multi-stage problems in which decisions at one stage become the conditions governing the succeeding stages. It can be applied to the management of water reservoirs, allowing them to be operated more efficiently. This is one of the few books dedicated solely to dynamic programming techniques used in reservoir management. It presents the applicability of these techniques and their limits on the operational analysis of reservoir systems. The dynamic programming models presented in this book have been applied to reservoir systems all over the world, helping the reader to appreciate the applicability and limits of these models. The book also includes a model for the operation of a reservoir during an emergency situation. This volume will be a valuable reference to researchers in hydrology, water resources and engineering, as well as professionals in reservoir management.
