One of the core areas of study in civil engineering concerns water that encompasses fluid mechanics, hydraulics and hydrology. Fluid mechanics provide the mathematical and scientific basis for hydraulics and hydrology that also have added empirical and practical contents. The knowledge contained in these three subjects is necessary for the optimal and equitable management of this precious resource that is not always available when and where it is needed, sometimes with conflicting demands. The objective of Fluid Mechanics, Hydraulics, Hydrology and Water Resources for Civil Engineers is to assimilate these core study areas into a single source of knowledge. The contents highlight the theory and applications supplemented with worked examples and also include comprehensive references for follow-up studies. The primary readership is civil engineering students who would normally go through these core subject areas sequentially spread over the duration of their studies. It is also a reference for practicing civil engineers in the water sector to refresh and update their skills.

Understanding that the natural world beneath our feet is the point at which civilization meets the natural world is critical to the success of restoration and prevention efforts to reduce contaminant impacts and improve the global environment because of one simple fact - contaminants do not respect country borders. Contaminants often begin their destructive journey immediately after being released and can affect the entire planet if the release is in just the right amount, at just the right location, and at just the right time. Taking an interdisciplinary approach, Urban Watersheds, Geology, Contamination, Environmental Regulations, and Sustainability, Second Edition presents more than 30 years of research and professional practice on urban watersheds from the fields of environmental geology, geochemistry, risk analysis, hydrology, and urban planning. The geological characteristics of urbanized watersheds along with the physical and chemical properties of their common contaminants are integrated to assess risk factors for soil, groundwater, and air. This new edition continues to examine the urban environment and the geology beneath urban areas, evaluates the contamination that affects watersheds in urban regions, and addresses redevelopment strategies. Features of the Second Edition: Examines contaminants and the successes of environmental regulation worldwide and highlights the areas that need improvement Describes several advances in investigation techniques in urban regions that now provide a huge leap forward in data collection, resolution, and accuracy Explains the importance of understanding the geological and hydrogeologic environments of urban and developed regions Provides new and enhanced methods presented as a sustainability model for assessing risks to human health and the environment from negative human-induced contaminant impacts Includes a new chapter that surveys how environmental regulations have been successful or have failed at protecting the air, water, and land in urban areas Suitable for use as a textbook and as a professional practice reference, the book includes case studies on successful and unsuccessful approaches to contaminant remediation as well as practical methods for environmental risk assessment. PowerPoint (R) presentations of selected portions of the book are available with qualifying course adoption. Daniel T. Rogers is currently the Director of Environmental Affairs at Amsted Industries Inc. in Chicago, Illinois. His writings address environmental geology, hydrogeology, geologic vulnerability and mapping, contaminant fate and transport, urban geology, environmental site investigations, contaminant risk, brownfield redevelopment, and sustainability. He has taught geology and environmental chemistry at Eastern Michigan University and the University of Michigan.

Analyzing the self-sufficient Danish island of Samso, this book explains sustainability through a bio-geophysical understanding of how to best use society's limited resources to achieve true sustainability. The method used derives from the thermodynamic function of exergy. By analyzing exergy flows and establishing a system for evaluating the energy and the materials used in a society, the author creates a platform for monitoring certain indicators of sustainability. These indicators inform readers about the actions that must be taken and the time frames for achieving sustainability goals. The exergy-based approach is an important tool for carrying out such an analysis because it Focuses on several key thermodynamic concepts and the usefulness of exergy analysis for evaluating sustainability Explains sustainability by implementing thermodynamic laws to societal consumption and the use of resources Discusses new methods that integrate energy and material fluxes and evaluates them against each other Provides direct indicators for finding the largest problems/obstacles and deciding where measures should be taken Includes instructions on how to establish an accounting system for evaluating the energy and the materials used in a society This book is aimed for professionals, researchers, and students working on nature conservation and environmental management projects related to sustainability.

Increasing demand for water, higher standards of living, depletion of resources of acceptable quality, and excessive water pollution due to urban, agricultural, and industrial expansions have caused intense environmental, social, economic, and political predicaments. More frequent and severe floods and droughts have changed the resiliency and ability of water infrastructure systems to operate and provide services to the public. These concerns and issues have also changed the way we plan and manage our surface and groundwater resources. Groundwater Hydrology: Engineering, Planning, and Management, Second Edition presents a compilation of the state-of-the-art subjects and techniques in the education and practice of groundwater and describes them in a systematic and integrated fashion useful for undergraduate and graduate students and practitioners. This new edition features updated materials, computer codes, and case studies throughout.

It discusses the classical issues in groundwater hydrology and hydraulics followed by coverage of water quality issues. It also introduces basic tools and decision-making techniques for future groundwater development activities, taking into account regional sustainability issues. The combined coverage of engineering and planning tools and techniques, as well as specific challenges for restoration and remediation of polluted aquifers sets this book apart.

Ever increasing urbanization is impacting both the quantity and quality of urban water resources. These urban water resources and components of the water cycle are likely to be affected severely. To minimize the consequences on world water resources, the development of sustainable water resources management strategies is inevitable. An integrated urban water resources management strategy is the key to maintain sustainable water resources. A preliminary understanding of physio-chemical processes and analysis methodologies involved in each and every component of the urban water cycle is necessary. In the past these components have been investigated and published individually. With the view to aiding the development of integrated urban water resources management strategies, this book endeavors to present and explain the major urban water cycle components from a single holistic platform. The book presents the introduction, analysis and design methods of a wide range of urban water components i.e., rainfall, flood, drainage, water supply and waste water with the additions of sustainability practices in most of the components. Current "Hydrology" and "Hydraulics" books do not incorporate sustainability features and practices, while there are many books on general "Sustainability" without integrating sustainability concepts into typical engineering designs. The book starts with components and classifications of world water resources, then basic and detailed components of the hydrologic cycle, climate change and its impacts on hydrologic cycle, rainfall patterns and measurements, rainfall losses, derivations of design rainfalls, streamflow measurements, flood frequency analysis and probabilistic flood estimations, deterministic flood estimations, unit hydrograph, flood modelling, commercial modelling tools and use of Geographical Information System (GIS) for flood modelling, principles of open channel hydraulics, critical flow and flow classification indices, open channel flow profiles, uniform flow in open channel and open channel design, estimation of future population and domestic water demand, design of water supply systems, sustainable water supply system, water treatments, wastewater quantification, wastewater treatments, sustainable and decentralized wastewater treatment, stormwater drainage and urban drainage analysis, water footprint and water-energy nexus, features of water conservation, harvesting and recycling, components of sustainable urban design, stormwater treatment and integrated water management.

This book presents new findings on intrinsic variability in pollutant build-up and wash-off processes by identifying the characteristics of underlying process mechanisms, based on the behaviour of various-sized particles. The correlation between build-up and wash-off processes is clearly defined using heavy metal pollutants as a case study. The outcome of this study is an approach developed to quantitatively assess process uncertainty, which makes it possible to mathematically incorporate the characteristics of variability in build-up and wash-off processes into stormwater quality models. In addition, the approach can be used to quantify process uncertainty as an integral aspect of stormwater quality predictions using common uncertainty analysis techniques. The information produced using enhanced modelling tools will promote more informed decision-making, and thereby help to improve urban stormwater quality.

The supply of reliable and safe water is a key challenge for developing countries, particularly India. Community management has long been the declared model for rural water supply and is recognised to be critical for its implementation and success. Based on 20 detailed successful case studies from across India, this book outlines future rural water supply approaches for all lower-income countries as they start to follow India on the economic growth (and subsequent service levels) transition. The case studies cover state-level wealth varying from US$2,600 to US$10,000 GDP per person and a mix of gravity flow, single village and multi-village groundwater and surface water schemes. The research reported covers 17 states and surveys of 2,400 households. Together, they provide a spread of cases directly relevant to policy-makers in lower-income economies planning to upgrade the quality and sustainability of rural water supply to meet the Sustainable Development Goals, particularly in the context of economic growth.

Climate change will present a series of challenges to engineers concerned with the provision of both building internal appliance drainage networks and rainwater systems within the building boundary, generally identified as the connection to the sewer network. Climate change is now recognised as presenting both water shortage and enhanced rainfall design scenarios. In response to predictions about immanent climate change Transient Free Surface Flows in Building Drainage Systems addresses problems such as the reduction in water available to remove waste from buildings, and conversely, the increase in frequency of tropical-type torrential rain. Starting with introductory chapters that explain the theories and principles of solid transport, free surface flows within drainage networks, and attenuating appliance discharge flows, this book allows readers from a variety of backgrounds to fully engage with this crucial subject matter. Later chapters apply these theories to the design of sanitary and rainwater systems. Case studies highlight the applicability of the method in assessing the appropriateness of design approaches. In this unique book, research in modelling for free surface flows at Edinburgh's Heriot-Watt University is drawn on to provide a highly authoritative, physics-based study of this complex engineering issue.

Droughts and their management are a serious challenge to water resource professionals. While droughts predominate in arid regions, their frequency and severity in more temperate regions with more abundant rainfall have been on the rise. Drought Management and Planning for Water Resources provides an essential collection of planning and management tools for minimizing the negative impacts of droughts. Comprehensive and up-to-date, it covers water conservation and reuse, conjunctive use and use of marginal resources, desalination, deep groundwater extraction, optimization modeling, and decision support systems. With contributions from a prestigious international panel, the book presents best management practices that maximize efficiency, reliability, and economy while minimizing the potential for adverse effects to the environment and human health. Providing appropriate methodologies, the chapters discuss how conjunctive water use can increase water availability in the developing world and what types of conjunctive use schemes are the most promising. The book examines the feasibility of a drought watch alert system and the legal and administrative framework required. It also explores the application of the Optimization Models and the Decision Support Systems to the study of different water management alternatives under drought conditions. Drought Management and Planning for Water Resources delineates how to reduce drought effects through pro-active vision, good management, and conjunctive use of water sources.

A practical book for professionals who rely on water quality data for decision making, this book is based on three decades experience of three highly published water and watershed resource professionals. It focuses on the analysis of air pollution sensitive waters and the consequent effects associated with soil and water acidification, nutrient-N enrichment, or the effects of atmospherically deposited toxic substances. It also covers lake zooplankton and/or stream macroinvertebrate biomonitors. Explanations of the reasons behind various recommendations provide readers with the tools needed to alter recommended protocols to match particular study needs and budget.

The basic types, of soil erosion and its measurement and estimation of runoff and soil loss from the small and large watersheds are discussed. Recent advances in the watershed management like the application of remote sensing and GIS and hydrological models are a part of the book. The book serve as a guide for professional and competitive examinations for undergraduate students of Agriculture and Agricultural Engineering and graduate students of Soil Science, Soil and Water Engineering, Agricultural Physics, Hydrology and Watershed Management.

Methanol is an important volatile organic compound (VOC) present in the gaseous and liquid effluents of process industries such as pulp and paper, paint manufacturing and petroleum refineries. An estimated 65% of the total methanol emission was from the Kraft mills of the pulp and paper industries. The effect of selenate, sulfate and thiosulfate on methanol utilization for volatile fatty acids (VFA) production was individually examined in batch systems. Gas-phase methanol removal along with thiosulfate reduction was carried out for 123 d in an anoxic BTF. To examine the gas-phase methanol removal along with selenate reduction, another anoxic biotrickling filter (BTF) was operated for 89 d under step and continuous selenate feeding conditions. For the study on liquid-phase methanol, acetogenesis of foul condensate (FC) obtained from a chemical pulping industry was tested in three upflow anaerobic sludge blanket (UASB) reactors operated at 22, 37 and 55 C for 51 d. The recovery of VFA was explored through adsorption studies using anion exchange resins in batch systems. The adsorption capacity of individual VFA on Amberlite IRA-67 and Dowex optipore L-493 was examined by fitting the experimental data to adsorption isotherms and kinetic models. A sequential batch process was tested to achieve selective separation of acetic acid from the VFA mixture.

The impacts of human-induced climate change are largely mediated by water, such as alterations in precipitation and glacial melt patterns, variations in river flow, increased occurrence of droughts and floods, and sea level rise in densely populated coastal areas. Such phenomena impact both urban and rural communities in developed, emerging, and developing countries. Taking a systems approach, this book analyzes evidence from 26 countries and identifies common barriers and bridges for local adaptation to climate change through water resources management. It includes a global set of case studies from places experiencing increased environmental and social pressure due to population growth, development and migration, including in Africa, Asia, Australia, Europe, North and South America. All chapters consider the crosscutting themes of adaptive capacity, equity, and sustainability. These point to resilient water allocation policies and practices that are capable of protecting social and environmental interests, whilst ensuring the efficient use of an often-scarce resource.

Since the second edition of this text was published, many new environmental incidents have occurred, including another nuclear disaster, a mine disaster in the United States, and the Gulf of Mexico oil spill. Updated throughout the text, Ecosystems and Human Health: Toxicology and Environmental Hazards, Third Edition explores the broad range of environmental and human health aspects of chemical and biological hazards-from natural toxins and disasters to man-made pollutants and environmental crises. The book begins with the basic principles of pharmacology and toxicology, risk analysis, and air, water, and soil pollution. It then examines various toxicants and hazards, such as airborne hazards, halogenated hydrocarbons, metals, and organic solvents. Chapters also discuss food additives and contaminants, pesticides, hormone disrupters, radiation hazards, and natural environmental hazards such as venomous and toxic animals. The text reviews the Chernobyl nuclear crisis and the Walkerton drinking water tragedy, as well as other disasters, assessing some of their long-term effects, now that sufficient time has elapsed since their occurrence. With updates in every chapter, this third edition contains significant expansion of information on the genetics of chemical carcinogenesis, global warming, food additives, invasive species in the Great Lakes, nuclear accidents, and more. The book describes how chemical toxins and biological hazards can impact the environment and the people who live in it. The author presents numerous examples of the relationship between ecosystem health and human health. He emphasizes the need to consider the environmental impact of human activities and includes many real-world examples and new case studies.

The development of technology in the emergency sanitation sector has not been emphasised sufficiently considering that the management of human excreta is a basic requirement for every person. The lack of technology tailored to emergency situations complicates efforts to cater for sanitation needs in challenging humanitarian crisis. Concerns persists on the lack of faecal sludge management that considers the whole sanitation chain from containment until treatment. This study focused on the development of a smart emergency toilet termed the eSOS (emergency sanitation operation system) smart toilet to address the limitation in technical options. This toilet is based on the eSOS concept that takes into account the entire sanitation chain. This study also addresses the limited time for planning in emergencies by developing a decision support system (DSS) to help quick selection of optimal sanitation options. The aim was to enable users of the DSS to plan their emergency sanitation response within the shortest time possible. The study aims to contribute toward a better emergency sanitation response by application of technology advances.

The Grand Ethiopian Renaissance Dam (GERD) will not only be Africa's largest dam, but it is also essential for future cooperation and development in the Nile River Basin and East African region. This book, after setting out basin-level legal and policy successes and failures of managing and sharing Nile waters, articulates the opportunities and challenges surrounding the GERD through multiple disciplinary lenses. It sets out its possibilities as a basis for a new era of cooperation, its regional and global implications, the benefits of cooperation and coordination in dam filling, and the need for participatory and transparent decision making. By applying law, political science and hydrology to sharing water resources in general and to large-scale dam building, filling and operating in particular, it offers concrete qualitative and quantitative options that are essential to promote cooperation and coordination in utilising and preserving Nile waters. The book incorporates the economic dimension and draws on recent developments including: the signing of a legally binding contract by Egypt, Ethiopia and Sudan to carry out an impact assessment study; the possibility that the GERD might be partially operational very soon, the completion of transmission lines from GERD to Addis Ababa; and the announcement of Sudan to commence construction of transmission lines from GERD to its main cities. The implications of these are assessed and lessons learned for transboundary water cooperation and conflict management.

It will provide information on an array of topics from instrumentation, analytical techniques, and sample preparations to statistical calculations, chemical structures, and equations. It will present the tools and techniques required to measure a wide range of toxic pollutants in our environment. It will be fully revised throughout, and will add four new chapters (Microbial Analysis, Chlorophyll, Chlorine, Chloramines and Chlorine Dioxide, and Derivatization Reactions in Environmental Analysis).

Around 6% of the Earth's land surface is covered by wetlands. Wetlands play a key role in hydrological and biogeochemical cycles, delivering multiple benefits to society: sources of water supply, flood regulation, water purification, agriculture, fisheries, and biodiversity. Hence, wetland systems are of immense socio-economic as well as ecological importance. In this research, the focus was on the Abras de Mantequilla (AdM) wetland in the tropical coastal region of Ecuador, a RAMSAR site and case study area for the EU-FP7 WETwin project. The research in this thesis involves a combination of field data collection, multivariate analysis techniques, as well as numerical modelling studies. The goal was to explore the effects of changes in hydrological forcing on the hydrodynamic and ecohydraulic responses of the wetland. The study aims to contribute to the understanding of how a tropical river-wetland system functions in terms of hydrodynamics, water quality, primary production, and biotic communities. Spatial patterns of biotic communities and environmental variables are obtained as well as spatio-temporal variability of hydrodynamics, water quality, primary productivity and fish habitat-suitability conditions. In data scarce areas and countries with financial constraints, the combination of field measurements with numerical models was extremely useful and relevant, confirming that these techniques complement each other in obtaining a better understanding of the dynamics of freshwater river-wetland systems. Studies like the present research can be used to enhance awareness about the environmental services of wetlands and stimulate cooperation between all stakeholders in order to achieve more sustainable wetland management.

A supplement to previous books edited by Afgan and Chau, this publication covers the practical aspects of analytical methodology for trace organics. The book reviews the published work on the occurance, distribution, fate, effect, and environmental impact of specific classes of compounds. Essential background information emphasizing practical aspects of various methods with respect to advantages and disadvantages of the published methods is also discussed.

The central focus of this volume is a critical comparative analysis of the key drivers for water resource management and the provision of clean water - governance systems and institutional and legal arrangements. The authors present a systematic analysis of case study river systems drawn from Australia, Denmark, Germany, the Netherlands, UK and USA to provide an integrated global assessment of the scale and key features of catchment management. A key premise explored is that despite the diversity of jurisdictions and catchments there are commonalities to a successful approach. The authors show that environmental and public health water quality criteria must be integrated with the economic and social goals of those affected, necessitating a 'twin-track' and holistic (cross-sector and discipline) approach of stakeholder engagement and sound scientific research. A final synthesis presents a set of principles for adaptive catchment management. These principles demonstrate how to integrate the best scientific and technical knowledge with policy, governance and legal provisions. It is shown how decision-making and implementation at the appropriate geographic and governmental scales can resolve conflicts and share best sustainable practices.

As urban growth outstrips water supplies, how can the global challenge of providing "liquid gold" be met? Mixing history and policy analysis, Steven Erie tells the compelling story of the Metropolitan Water District of Southern California (MWD)-one of the world's largest and most important public water agencies-and its role in building the world's 8th largest economy in a semi-desert. No tawdry tale of secret backroom conspiracies-as depicted in the famed film noir Chinatown-this fresh telling concerns an unheralded regional institution, its entrepreneurial public leadership, and pioneering policymaking. Using untapped primary sources, the author re-examines this great regional experiment from its obscure 1920s-era origins, through the Colorado River Aqueduct and State Water Projects, to today's daunting mission of drought management, water quality, environmental stewardship, and post-9/11 supply security. A key focus is MWD's navigation of recent epic water battles: San Diego's combative quest for water independence from MWD and L.A.; lingering conflicts over the Colorado River and northern California's fragile Bay-Delta ecosystem; and the myriad challenges posed by water markets, privatization, and water transfers. Facing unprecedented challenges, MWD is devising innovative formulas to sustain this improbable desert civilization. Beyond Chinatown concludes by considering MWD's Integrated Resources Plan as a global model for water-resources planning and management, water supply diversification and reliability, affordability, and environmental sustainability. Chinatown's seductive mythologies have obscured MWD's authentic, instructive history and lessons. Praise for Steve Erie's previous book, Globalizing L.A.: "This book is a must-read for anyone interested in the politics of Western cities, the politics of urban development, and especially the future politics of cities that are likely to be contenders in the increasingly competitive arena of global trade. . . . Erie's analysis will forever direct us to look first at certain public agencies to begin to understand larger patterns of economic growth in any metropolitan area."-Journal of Urban Affairs "[A] fascinating history of the Los Angeles region's great assets and the forces that drove their development. . . . One hundred years ago, it was improbable that the Los Angeles region would become the 10th largest economy in the world. In Globalizing L.A., Erie explains how that happened and then, fingers crossed, offers lessons on how California's largest and most diverse city and region can keep playing a leading role."-Los Angeles Times "Referencing an impressive body of recent academic research, Erie argues that world-class seaport and airport facilities confer substantial economic advantages and more facilitating links between local businesses and the global economy."-The Sacramento Bee "Erie has built a potent political-economy of urban development that recognizes the crucial role of the public sector in mediating globalizing processes . . . and this is a valuable lesson for academics, dockworkers, community developers, and environmental activists alike."-Economic Geography

This book is an initial attempt to estimate the loads of heavy metal and nutrient loads into an industrial effluent receiving rivers of a typical industrializing catchment. It shows the effects and impacts of diffuse and point sources of these loads into the rivers, and illuminate management, capacity and policy gaps of riverine water and sediment monitoring in the sub-Saharan countries perspective from Ethiopia. The study was done in semi-arid catchments of Kombolcha city with industrialising urban and peri-urban areas in north-central Ethiopia. The Leyole and Worka rivers, which receives industrial effluent and wash-off from the catchments' areas, were monitored for two years. This book contribute to our understanding on applicable methods to quantify loads of diffuse and point sources in data poor areas, and the most important contribution is to address the gaps in in controlling emission changes and. The results of this book contribute to the theory of river protection and understanding of water quality management of sub-Saharan African tropical rivers and sediments and provides policy options for improvement in rivers water quality of the sub-Saharan countries. In bridging this gap, this book proposed a model to estimate the total loads of nitrogen and phosphorus from a catchment.

The availability of Earth observation and numerical weather prediction data for hydrological modelling and water management has increased significantly, creating a situation that today, for the same variable, estimates may be available from two or more sources of information. Yet, in hydrological modelling, usually, a particular set of catchment characteristics and input data is selected, possibly ignoring other relevant data sources. In this thesis, therefore, a framework is being proposed to enable effective use of multiple data sources in hydrological modelling. In this framework, each available data source is used to derive catchment parameter values or input time series. Each unique combination of catchment and input data sources thus leads to a different hydrological simulation result: a new ensemble member. Together, the members form an ensemble of hydrological simulations. By following this approach, all available data sources are used effectively and their information is preserved. The framework also accommodates for applying multiple data-model integration methods, e.g. data assimilation. Each alternative integration method leads to yet another unique simulation result. Case study results for a distributed hydrological model of Rijnland, the Netherlands, show that the framework can be applied effectively, improve discharge simulation, and partially account for parameter and data uncertainty.
