The aim of this book is to present the potential benefits as well as the challenges of introducing a more formal economic regulatory process into the urban water sector arena in lower-income countries. There is a particular focus upon the impact this may have on the poorest, the informal, slum and shanty dwellers of the rapidly growing cities. Economic regulation, usually introduced in the context of private operation of monopoly water supply, can deliver objectivity and transparency in the price-setting process for public providers also. But this is not, as is commonly assumed, primarily to protect the customer from the provider; rather it is to allow the service provider to set something approaching cost-reflective tariffs. These charges, almost certainly higher than previously, perversely can benefit the poor who have been paying far more for informal access to any piped supplies. With the addition of a regulatory duty to achieve some form of adaptive Universal Service Obligation, economic regulation could contribute significantly to the achievement of the Millennium Development Goals in urban areas.The book describes and analyzes these issues through a consideration of ten country case studies. As a starting point, the current situation for the provision of water and sanitation services for the poorest through non-regulated public providers in India and Uganda is reviewed. Comparative chapters are then presented on Argentina, Ghana, Philippines, Bolivia, Jordan, Zambia and Indonesia, all with varying degrees of private sector involvement and regulation. Finally, the experiences of the two richest countries, Chile and England, are considered, investigating service to the poor inthese examples with the longest experience of economic regulation and the "most privatized" suppliers. In all cases there is a focus on the very necessary role of customer involvement in price-setting and service monitoring and on the role of alternative (private) service providers within the context of the need for least cost utility service provision to all.

In the wake of the devastating 1906 earthquake and fire, the city of San Francisco desperately needed reliable supplies of water and electricity. Its mayor, James Phelan, pressed for the damming of the Tuolumne River in the newly created Yosemite National Park, setting off a firestorm of protest. For the first time in American history, a significant national opposition arose to defend and preserve nature, led by John Muir and the Sierra Club, who sought to protect what they believed was the right of all Americans to experience natural beauty, particularly the magnificent mountains of the Yosemite region. Yet the defenders of the valley, while opposing the creation of a dam and reservoir, did not intend for it to be maintained as wilderness. Instead they advocated a different kind of development--the building of roads, hotels, and an infrastructure to support recreational tourism. Using articles, pamphlets, and broadsides, they successfully whipped up public opinion against the dam. Letters from individuals began to pour into Congress by the thousands, and major newspapers published editorials condemning the dam. The fight went to the floor of Congress, where politicians debated the value of scenery and the costs of western development. Ultimately, passage of the passage of the Raker Act in 1913 by Congress granted San Francisco the right to flood the Hetch Hetchy Valley. A decade later the O'Shaughnessy Dam, the second largest civil engineering project of its day after the Panama Canal, was completed. Yet conflict continued over the ownership of the watershed and the profits derived from hydroelectrocity. To this day the reservoir provides San Francisco with a pure and reliable sourceof drinking water and an important source of power. Although the Sierra Club lost this battle, the controversy stirred the public into action on behalf of national parks. Future debates over dams and restoration clearly demonstrated the burgeoning strength of grassroots environmentalism. In a narrative peopled by politicians and business leaders, engineers and laborers, preservationists and ordinary citizens, Robert W. Righter tells the epic story of the first major environmental battle of the twentieth century, which reverberates to this day.

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.

Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.

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

Improving agricultural water use efficiency (WUE) is vitally important in many parts of the world due to the decreasing availability of water resources and the increasing competition for water between different users. Micro irrigation is an effective tool for conserving water resources. Studies have revealed a significant water savings, ranging from 40% to 70% under drip irrigation compared with surface irrigation. This new volume, Engineering Interventions in Sustainable Trickle Irrigation: Irrigation Requirements and Uniformity, Fertigation, and Crop Performance, presents valuable research that evaluates crop water and fertigation requirements, examines optimum irrigation and fertigation scheduling, and analyzes the performance of agricultural crops under micro irrigation. With an interdisciplinary perspective, this volume addresses the urgent need to explore and investigates the current shortcomings and challenges of water resources engineering, especially in micro irrigation engineering. The volume discusses crop water requirements, fertigation technology, and performance of agricultural crops under best management practices. The chapter authors present research studies on drip irrigated tomato, chilies, cucumber, eggplant, cabbage, garlic, sugarcane maize, cashew nut, sapota, banana, mango, and blueberries. Removing the research gap, this volume provides new information that will be valuable to those involved in micro irrigation engineering.

Global climate change is typically understood and modeled using global climate models (GCMs), but the outputs of these models in terms of hydrological variables are only available on coarse or large spatial and time scales, while finer spatial and temporal resolutions are needed to reliably assess the hydro-environmental impacts of climate change. To reliably obtain the required resolutions of hydrological variables, statistical downscaling is typically employed. Statistical Downscaling for Hydrological and Environmental Applications presents statistical downscaling techniques in a practical manner so that both students and practitioners can readily utilize them. Numerous methods are presented, and all are illustrated with practical examples. The book is written so that no prior background in statistics is needed, and it will be useful to graduate students, college faculty, and researchers in hydrology, hydroclimatology, agricultural and environmental sciences, and watershed management. It will also be of interest to environmental policymakers at the local, state, and national levels, as well as readers interested in climate change and its related hydrologic impacts. Features: Examines how to model hydrological events such as extreme rainfall, floods, and droughts at the local, watershed level. Explains how to properly correct for significant biases with the observational data normally found in current Global Climate Models (GCMs). Presents temporal downscaling from daily to hourly with a nonparametric approach. Discusses the myriad effects of climate change on hydrological processes.

The management of water resources across boundaries, whether sub-national or international, is one of the most difficult challenges facing water managers today. The upstream exploitation or diversion of groundwater or rivers can have devastating consequences for those living downstream, and transboundary rivers can provide a source of conflict between nations or states, particularly where water resources are scarce. Similarly, water based-pollution can spread across borders and create disputes and a need for sound governance. This book is the first to bring together in a concise and accessible way all of the main topics to be considered when managing transboundary waters. It will raise the awareness of practitioners of the various issues needed to be taken into account when making water management decisions and provide a practically-based overview for advanced students. The authors show clearly how vital it is to cooperate effectively over the management of shared waters to unlock their contribution to regional sustainable development. The book is largely based on a long-running and tested international training programme, run by the Stockholm International Water Institute and Ramboll Natura, and supported by the Swedish International Development Co-operation Agency (Sida), where the respective authors have presented modules on the programmes. It addresses issues not only of conflict, but also of managing power asymmetries, benefit-sharing, stakeholder participation, international water law, environmental water requirements and regional development. It will be particularly useful for those with a background in hydrology or engineering who wish to broaden their management skills.

The protection of water resources from deterioration in quality by pollution discharges is probably the biggest challenge in sustainable water resources management in the recent decades. In practice, most countries have adopted pollution control strategies and measures which are based on 'end-of-pipe' solutions: wastewater treatment plants and adjustments to the regulations, including taxes for wastewater discharges (Conventional Strategy). Although this approach involves very high costs, on many occasions, this strategy has been a complete failure. The research described in this book contribute to the development of sustainable solutions for the previously outlined problem. It was based on the validation of the Three-Step Strategic Approach concept (3-SSA), which includes: 1) prevention or minimisation of waste production; 2) treatment aimed at recovery and reuse of waste components, and 3) disposal of remaining waste with stimulation of natural self-purification of the receiving water body. The study showed overall positive effects of the 3-SSA, in comparison of Conventional Strategy, on wastewater management in the Upper Basin (389 km) of the Cauca river, the second most important river in Colombia. The Cost Benefit Analysis clearly favoured the 3-SSA, generating a major impact on the river water quality at lower cost compared to the Conventional Strategy.

In recent years the water sector has undergone profound institutional, economic and political transformations. Some countries have encouraged privatization of water services, but in many cases this has provoked adverse reaction to such a neoliberal and market-based approach to this common shared but essential resource. This book goes beyond the ideology of the public versus private water regime debate, by focusing on the results of these types of initiatives to provide better water services, particularly in urban settings. It provides numerous examples of alternative models, to show who is responsible for implementing such systems and what are their social, institutional and technical-scientific characteristics. Policies are analysed in terms of their implications for employees and residents. The book presents a new combinatory approach of water regimes, based on several international case studies (Argentina, Bolivia, China, France, Germany, India, South Africa and the USA, plus a comparison of three cities in Africa) presenting specific challenges for water models. These case studies demonstrate the successes and problems of a range of private sector involvements in the provision of water services, and provide examples of how small-scale systems can compare with larger-scale more technical systems.

Water Quality Data emphasizes the interpretation of a water analysis or a group of analyses, with major applications on ground-water pollution or contaminant transport. A companion computer program aids in obtaining accurate, reproducible results, and alleviates some of the drudgery involved in water chemistry calculations.
The text is divided into nine chapters and includes computer programs applicable to all the main concepts presented. After introducing the fundamental aspects of water chemistry, the book focuses on the interpretation of water chemical data. The interrelationships between the various aspects of geochemistry and between chemistry and geology are discussed. The book describes the origin and interpretation of the major elements, and some minor ones, that affect water quality.
Readers are introduced to the elementary thermodynamics necessary to understand the use and results from water equilibrium computer programs. The book includes a detailed overview of organic chemistry and identifies the simpler and environmentally important organic chemicals. Methods are given to estimate the distribution of organic chemicals in the environment. The author fully explains all accompanying computer programs and presents this complex topic in a style that is interesting and easy to grasp for anyone.

One of the seventeen critical infrastructures vital to the security of the United States, the water supply system remains largely unprotected from the threat of terrorism, including possible revenge by Al Qaeda over the killing of Osama Bin Laden. Recognizing and identifying prospective events of terrorism against the water infrastructure is critical to the protection of the nation, as the consequences triggered by a terrorist attack on the water supply would be devastating. Risk Assessment for Water Infrastructure: Safety and Security provides a unique quantitative risk assessment methodology for protection and security against terrorist contamination, vandalism, attacks against dams, and other threats to water supply systems. Focusing on the human safety, environmental, and economic consequences triggered by potential terrorist attacks and other threats, the book presents: The development of an integrated approach of risk assessment based upon the cumulative prospect theory The qualitative/quantitative processes and models for security and safe facility operations as required by EPA, DHS, and other governmental and regulatory agencies The application of an integrated model to the risk assessment of surface water, dams, wells, wastewater treatment facilities, reservoirs, and aqueducts of large urban regions The development of intelligence analysis incorporating risk assessment for terrorism prevention Finally, the book presents the legal and regulatory requirements and policy related to the protection and security of water infrastructure from terrorism and natural hazards to both human health and the environment. By analyzing potential terrorist risks against the water supply, strategic improvements in U.S. water infrastructure security may be achieved, including changes in policy, incorporation of intrusion detection technology, increased surveillance, and increased intelligence.

Modern Land Drainage 2nd edition is a fully revised and updated edition of the 2004 edition. Modern Land Drainage describes traditional drainage formulas (Hooghoudt, Kirkham, Donnan, Ernst, Glover-Dumm) for rainfed agriculture in the humid temperature zone. Significant parts are devoted to drainage for salinity control of irrigated land in (semi-) arid zones, and to drainage of rice land in the humid tropics. Institutional, management and maintenance aspects are extensively covered, as well as the mitigation of adverse impacts of drainage interventions on the environment. The latest computer applications for drainage design in the context of integrated water management are described (DRAINMOD, HEC, SWAP, etc.). Field surveys are executed by governments, with the aid of consultants, but rarely are the end stakeholders (i.e., farmers and general public) involved from inception to planning to execution of a drainage system. Yet, during the Operation, Management and Maintenance (OMM) phase of a water management system, they are expected to takeover, run, bear and be responsible for the costs of OMM. The book describes successful methodologies and processes to be followed for engagement of stakeholders at all levels, from government to farm, from minister to farmer, and, from beginning to end. The book covers all aspects needed for sustainable drainage. The latest survey methodologies with satellites and drones are suggested to assess cause and effect. Waterlogging and salinity are the effect of something caused most likely upstream of the drainage problem location. Hence treating the cause may be more cost-effective. Triple Bottom Line (social, environmental and financial considerations) and the water-food-energy nexus are an integral part of the drainage design process. Controlled drainage, i.e. the balance of removal and conservation of drainage water and minimising solute transport as low as reasonably achievable (ALARA principle) is extensively described. This work is intended for use both as a university level textbook and as a professional handbook; it is of particular value to professionals engaged in drainage development in the context of integrated water resources and river basin management, civil and agricultural engineers, government officials, university students and libraries.

The vocabulary and discourse of water resource management have expanded vastly in recent years to include an array of new concepts and terminology, such as water security, water productivity, virtual water and water governance. While the new conceptual lenses may generate insights that improve responses to the world's water challenges, their practical use is often encumbered by ambiguity and confusion. This book applies critical scrutiny to a prominent set of new but widely used terms, in order to clarify their meanings and improve the basis on which we identify and tackle the world's water challenges. More specifically, the book takes stock of what several of the more prominent new terms mean, reviews variation in interpretation, explores how they are measured, and discusses their respective added value. It makes many implicit differences between terms explicit and aids understanding and use of these terms by both students and professionals. At the same time, it does not ignore the legitimately contested nature of some concepts. Further, the book enables greater precision on the interpretational options for the various terms, and for the value that they add to water policy and its implementation.

This book discusses the development of useful models and their applications in soil and water engineering. It covers various modeling methods, including groundwater recharge estimation, rainfall-runoff modeling using artificial neural networks, development and application of a water balance model and a HYDRUS-2D model for cropped fields, a multi-model approach for stream flow simulation, multi-criteria analysis for construction of groundwater structures in hard rock terrains, hydrologic modeling of watersheds using remote sensing, and GIS and AGNPS.

Sorption technique was employed to remove heavy metals from gold mining effluent using natural and plant materials for sustainability. An assessment of the effluent quality of a gold mining company in Ghana indicated that arsenic, copper and cyanide were the major pollutants in the process effluent. Arsenic and copper were successfully removed from the effluent by the studied materials. The research showed that the down-flow fixed-bed treatment configuration is an ideal system for the simultaneous removal of copper and arsenic from low concentration gold mining effluent, in addition to other heavy metals present in very low concentrations.

At the UN General Assembly in 1997, an overwhelming majority of States voted for the adoption of the United Nations Convention on the Law of the Non-Navigational Uses of International Watercourses - a global overarching framework governing the rights and duties of States sharing freshwater systems. Globally, there are 263 internationally shared watersheds, which drain the territories of 145 countries and represent more than forty percent of the Earth's land surface. Hence, inter-State cooperation towards the sustainable management of transboundary water supplies, in accordance with applicable international legal instruments, is a topic of crucial importance, especially in the context of the current global water crisis. This volume provides an assessment of the role and relevance of the UN Watercourses Convention and describes and evaluates its entry into force as a key component of transboundary water governance. To date, the Convention still requires further contracting States before it can enter into force. The authors describe the drafting and negotiation of the Convention and its relationship to other multilateral environmental agreements. A series of case studies assess the role of the Convention at various levels: regional (European Union, East Africa, West Africa, Central Asia, Central America and South America), river basin (e.g. the Mekong and Congo) and national (e.g. Ethiopia and Mexico). The book concludes by proposing how future implementation might further strengthen international cooperation in the management of water resources, to promote biodiversity conservation as well as sustainable and equitable use.

Water management challenges in many basins of Sub-Saharan Africa are increasing due to rapid urbanisation, poverty and food insecurity, energy demands, and climate change. These challenges put additional demands on existing water institutions, and their capacity to reconcile competing claims. In addition to supply augmentation measures, solving water competition and conflict requires crafting new governance arrangements that can ensure equitable and sustainable use of the limited water resources. This book discusses how instead of harmony, state intervention in the water sector appears to generate dissonance at the interface with locally evolved water institutions. The book describes and analyses how local level innovation in institutional arrangements for water sharing often emerged around the creation of hydraulic property and/or is negotiated to secure more water flow for downstream users. Unlike most research on collective action in which water asymmetry, inequality and heterogeneity are seen as risks to collective action, the book discusses how they instead dynamically interact and give rise to interdependencies between water users which facilitate coordination and collective action. The book describes in detail cooperative arrangements as well as conflicts between large- and small-scale irrigation farmers, as well as between irrigation farmers and cities in an African context. The book makes a novel contribution to existing theories and concepts related to catchment water management. It expands the typology of basin actors' responses by explicitly introducing a meso layer which depicts the interface where state-led and local-level initiatives and responses are played out. The book also provides conceptual clarity on the dynamics between water asymmetry, inequality in access to land, and heterogeneity sustaining collective action over common pool resources. It further shows that not all the eight institutional design principles proposed by Ostrom (1993) are necessary for a water institution to be effective and to endure over time.
