Water Security
by Water Initiative The World Economic ForumAt the 2008 Davos Annual Meeting, UN Secretary General Ban Ki-Moon identified water as "the climate adaptation issue," directing the World Economic Forum to assemble the world's foremost group of public, private, non-governmental-organization and academic experts to examine the impending global water crisis from all perspectives. The result of their work is this forecast--a stark, non-technical overview of where we will be by 2025 if we continue to (mis)manage our water resources. Water Security contains compelling commentary from leading decision-makers, past and present. The commentary is supported by analysis from leading academics of how the world economy will be affected if world leaders cannot agree on solutions. The findings are shocking. Perhaps equally stunning are the potential solutions and the recommendations that the group presents. All are included in this landmark publication.

Water Security in Asia: Opportunities and Challenges in the Context of Climate Change (Springer Water)
by Mukand Babel Andreas Haarstrick Lars Ribbe Victor R. Shinde Norbert DichtlThis book assesses the current water-security situation in Asia. The thematic areas of the book discuss the United Nation’s sustainable development goals with a particular focus on Goal 6 (“Ensure availability and sustainable management of water and sanitation”) and Goal 13 (“Take urgent action to combat climate change and its impacts”). Asia has been facing a number of water-related challenges for decades due to multiple factors such as increasing population, socio-economic development, urbanization and migration, and climate change now poses an additional threat. While significant efforts have been made by governments in Asia, much more work is needed to make Asian societies water-secure. Given its multi-disciplinary approach, the book is a valuable resource for researchers involved in the further development of water-security concepts, approaches, and methodologies. In addition, it helps policymakers, planners, and practitioners to formulate sustainable water- security enhancement strategies grounded in sound scientific evidence to protect human well-being.
Water Security in the Mediterranean Region
by Andrea Scozzari Bouabid El MansouriThe role of water in our communities, from local to regional and right up to global levels, poses a series of key questions about climate change, about the anthropogenic impact on the environment, and about all the interconnected actions and events that affect the availability and quality of the resource. All these questions share a common demand for more scientific knowledge and information. In this particular context the disciplinary boundaries are fading, and there is a growing need to create broader connections and wider collaborative interdisciplinary groups, aimed at building an integrated knowledge-base to serve not only stakeholders but also the whole of society. Only in this way can we hope to respond effectively to the challenges and changing dynamics of human-hydrologic systems. Following this concept, contributors from multiple disciplinary backgrounds, such as Law Studies, Hydrogeology, Monitoring and Information Technologies, Geophysics, Geochemistry, Environmental Sciences, Systems Engineering, Economics and Social Studies, joined forces and interacted in this workshop. The present book reports the proceedings of this three-day ARW (Advanced Research Workshop), and explores different aspects of the environmental security assessment process, focusing on the assessment, monitoring and management of water resources, and giving an overview of the related scientific knowledge.
Water-Soluble Synthetic Polymers: Volume II: Properties and Behavior
by Philip MolyneuxAlthough several monographs and reviews have appeared on individual polymers of this type, and their applications and other technical aspects have also been discussed, this is apparently the first book to deal with the physical chemistry of water-soluble synthetic polymers as a group. This collective survey enables their properties and behaviour to be compared, and to be correlated with their molecular structures for predictive purposes. However, this has made it necessary to critically re-appraise much of the earlier fundamental work, so that current discussion of more recent work can be put on ta proper basis. Thus, of the 1800 or so references cited, the middle two-thirds related to the twenty-year period centred on about 1968. Nevertheless, sufficient key recent references have also been included so that the existing ‘state of the art is delineated.

Water Stress in Biological, Chemical, Pharmaceutical and Food Systems
by Gustavo F. Gutiérrez-López Liliana Alamilla-Beltrán María del Pilar Buera Jorge Welti-Chanes Efrén Parada-Arias Gustavo V. Barbosa-CánovasWater Stress Management contains the invited lectures and selected oral and poster presentations of the 11th International Symposium on the Properties of Water (ISOPOW), which was held in Queretaro, Mexico 5-9 September 2010. The text provides a holistic description and discussion of state-of-the-art topics on the role of water in Biological, Chemical, Pharmaceutical and Food systems within a frame of an integrated approach and future trends on the subject. Different points-of-view about the state of water and phase transitions in a variety of substrates are presented. ISOPOW is a non-profit scientific organization whose activities aim at progressing the understanding of the properties of water in food and related biological systems and the exploitation of this understanding in improved raw materials, products and processes in the food, agro food or related industries. The first Symposium was organized in Glasgow, Scotland in 1974. Since then, ISOPOW meetings have promoted the exchange of knowledge between scientists involved in the study of food materials and scientists interested in water from a more basic point of view and the dialogue between academic and industrial scientists/technologists.
Water Supply and Demand Management in the Galápagos: A Case Study of Santa Cruz Island
by Maria Fernanda Reyes PerezWater resources in tourist islands have been severely threatened, especially in the Galápagos Islands, where the increased local population has generated attractive income from the tourist services. In addition, the data regarding water supply and demand are scarce. This study investigates water supply and demand in Santa Cruz, the most populated island of Galápagos. The research encompasses a thorough assessment of the water supply crisis, as well as the quantification of water demand from different categories (domestic, tourist, restaurants and laundries) through surveys, in the absence of water metering. Also, specific water demand was assessed by installing 18 water meters. The results yield a wide range of water consumption, questioning the current assumption of water scarcity. Furthermore, a prognosis of water supply and demand was carried out, and also several intervention strategies were proposed such as rainwater harvesting, greywater recycling, leakage reduction, water meter installation, water demand reduction, as well as seawater desalination to cope with the future population growth. Due to the fragility of the ecosystem, these strategies were assessed through a Multi-Criteria Decision Analysis, considering environmental, technical, economic and social aspects, as well as relevant stakeholders’ perspectives. finally, the water supply network of Puerto Ayora was evaluated in order to understand the need of the current intermittent supply regime. A methodology was developed to estimate the overflow of the domestic roof tanks (a common incidence amongst local population). The results question the practicality of individual household storage. The final results show that the current situation in terms of the lack of water quantity may not be real, as it has been thought for the last decades. The water issues refer more importantly to the water quality, as well as to the lack of proper water management practices.

Water, Sustainable Development and the Nexus: Response to Climate Change (Water)
by Velma I. Grover Amani AlfarraWater is intricately linked with food security, energy security, and sustainable development. As the world is moving towards sustainable development goals, it is critical to recognize the role of water in attaining these goals. The Water-Energy-Food Nexus draws attention to the complex and interrelated nature of global resource systems and forces us to think about how a decision in one sector impacts other interlinked sectors as well. This book looks at the three dimensions of sustainable development-environment, economics and society-and how water is linked with them and explores the nexus approach as a framework to look at the issues and identify solutions.
Water Systems Analysis, Design, and Planning: Urban Infrastructure
by Mohammad KaramouzThis book presents three distinct pillars for analysis, design, and planning: urban water cycle and variability as the state of water being; landscape architecture as the medium for built-by-design; and total systems as the planning approach. The increasing demand for water and urban and industrial expansions have caused myriad 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 water resources. Focusing on urban challenges and contexts, the book provides foundational information regarding water science and engineering while also examining topics relating to urban stormwater, water supply, and wastewater infrastructures. It also addresses critical emerging issues such as simulation and economic modeling, flood resiliency, environmental visualization, satellite data applications, and digital data model (DEM) advancements. Features: Explores various theoretical, practical, and real-world applications of system analysis, design, and planning of urban water infrastructures Discusses hydrology, hydraulics, and basic laws of water flow movement through natural and constructed environments Describes a wide range of novel topics ranging from water assets, water economics, systems analysis, risk, reliability, and disaster management Examines the details of hydrologic and hydrodynamic modeling and simulation of conceptual and data-driven models Delineates flood resiliency, environmental visualization, pattern recognition, and machine learning attributes Explores a compilation of tools and emerging techniques that elevate the reader to a higher plateau in water and environmental systems management Water Systems Analysis, Design, and Planning: Urban Infrastructure serves as a useful resource for advanced undergraduate and graduate students taking courses in the areas of water resources and systems analysis, as well as practicing engineers and landscape professionals.
Water, Technology and the Nation-State (Earthscan Studies in Water Resource Management)
by Erik Swyngedouw Filippo MengaJust as space, territory and society can be socially and politically co-constructed, so can water, and thus the construction of hydraulic infrastructures can be mobilised by politicians to consolidate their grip on power while nurturing their own vision of what the nation is or should become. This book delves into the complex and often hidden connection between water, technological advancement and the nation-state, addressing two major questions. First, the arguments deployed consider how water as a resource can be ideologically constructed, imagined and framed to create and reinforce a national identity, and secondly, how the idea of a nation-state can and is materially co-constituted out of the material infrastructure through which water is harnessed and channelled. The book consists of 13 theoretical and empirical interdisciplinary chapters covering four continents. The case studies cover a diverse range of geographical areas and countries, including China, Cyprus, Egypt, Ethiopia, France, Nepal and Thailand, and together illustrate that the meaning and rationale behind water infrastructures goes well beyond the control and regulation of water resources, as it becomes central in the unfolding of power dynamics across time and space.
Water Technology in the Middle Ages: Cities, Monasteries, and Waterworks after the Roman Empire (Johns Hopkins Studies in the History of Technology)
by Roberta J. MagnussonFocusing attention on gravity-fed water-flow systems in medieval cities and monasteries, Water Technology in the Middle Ages: Cities, Monasteries, and Waterworks after the Roman Empire challenges the view that hydraulic engineering died with the Romans and remained moribund until the Renaissance. Roberta Magnusson explores the systems' technologies—how they worked, what uses the water served—and also the social rifts that created struggles over access to this basic necessity.Mindful of theoretical questions about what hastens technological change and how society and technology mutually influence one another, the author supplies a thoughtful and instructive study. Archeological, historical, and literary evidence vividly depicts those who designed, constructed, and used medieval water systems and demonstrates a shift from a public-administrative to a private-innovative framework—one that argues for the importance of local initiatives. "The following chapters attempt to chart a course between the Scylla and Charybdis of technological and social determinism. While writing them, I have tried to strike a balance between the technical and human aspects of medieval hydraulic systems, and to remember that beneath the welter of documents and diffusion patterns, configurations and components, ordinances and expenditures, lie the perceptions, the choices, and often the plain hard work of individual men and women." —from the Preface

Water Trading and Global Water Scarcity: International Experiences (RFF Press Water Policy Series)
by Josefina MaestuWater scarcity is an increasing problem in many parts of the world, yet conventional supply-side economics and management are insufficient to deal with it. In this book the role of water trading as an instrument of integrated water resources management is explored in depth. It is also shown to be an instrument for conflict resolution, where it may be necessary to reallocate water in the context of increasing scarcity. Recent experiences of implementation in different river basins have shown their potential as instruments for improving allocation. These experiences, however, also show that there are implementation challenges and some limitations to trading that need to be considered. This book explores the various types of water trading formulas through the experience of using them in different parts of the world. The final result is varied because, in most cases, trading is conditioned by the legal and institutional framework in which the transactions are carried out. The role of government and the definition of water rights and licenses are critical for the success of water trading. The book studies the institutional framework and how transactions have been undertaken, drawing some lessons on how trading can improve. It also analyses whether trading has really been a positive instrument to manage scarcity and improve water ecosystems and pollution emission problems in those parts of the world which are most affected. The book concludes by making policy proposals to improve the implementation of water trading.

Water Treatment in Urban Environments: Examples from South/Southeast Asia (Applied Environmental Science and Engineering for a Sustainable Future)
by Veeriah Jegatheesan Perlie Velasco Nevelina PachovaThe value of implementing nature-based solutions (NbS) for water treatment in urban environments is increasingly recognized due to the multiple ecosystem services and societal benefits they provide. The successful implementation of NbS for urban water treatment, however, depends on a range of diverse technical and societal factors that need to be taken into account. Those vary by the type of NbS implemented, the societal challenges the NbS are designed to address and the local ecological, socio-economic and political context, in which the solutions are implemented. This book provides a collection of guidelines for the implementation of three types of NbS for water treatment in urban environments across cities in South/Southeast Asia, namely constructed wetlands, green roofs and floating treatment wetlands. The guides were developed based on existing experiences with the establishment, operation, and maintenance of those three types of NbS in three different countriesin South/Southeast Asia and the lessons learnt from their implementation. They provide detailed outlines of suggested steps for ensuring successful implementation in the respective local contexts. Those include overall planning schemes, surveys for socio-economic evaluations, suggested methods for construction and associated costs, required maintenance as well as a range of operational monitoring parameters. It also includes examples of approaches for the scaling of the three types of NbS discussed in the book in their respective local contexts. This book is expected to benefit local government units and contractors, and other stakeholders involved in NbS implementation and up-scaling, as well as researchers and postgraduate students who plan to conduct pilot-scale studies on NbS.

Water Waves: The Mathematical Theory With Applications (Dover Books on Physics)
by James Johnston StokerFirst published in 1957, this is a classic monograph in the area of applied mathematics. It offers a connected account of the mathematical theory of wave motion in a liquid with a free surface and subjected to gravitational and other forces, together with applications to a wide variety of concrete physical problems. A never-surpassed text, it remains of permanent value to a wide range of scientists and engineers concerned with problems in fluid mechanics.The four-part treatment begins with a presentation of the derivation of the basic hydrodynamic theory for non-viscous incompressible fluids and a description of the two principal approximate theories that form the basis for the rest of the book. The second section centers on the approximate theory that results from small-amplitude wave motions. A consideration of problems involving waves in shallow water follows, and the text concludes with a selection of problems solved in terms of the exact theory. Despite the diversity of its topics, this text offers a unified, readable, and largely self-contained treatment.
Water Waves and Ship Hydrodynamics: An Introduction
by A. J. HermansIn this book an introduction is given to aspects of water waves that play a role in ship hydrodynamics and offshore engineering. At first the equations and linearized boundary conditions are derived describing the non-viscous free surface water waves, with special attention to the combination of steady and non-steady flow fields. Then some simple kinds of free wave solutions are derived, such as plane waves and cylindrical waves. For several situations, steady and unsteady, the source singularity function is derived. These functions play a role in numerical codes used to describe the motion of ships and offshore structures. These codes are mostly based on a boundary integral formulation; therefore we give an introduction to these methods. It is shown how first order ship motions can be determined. In offshore engineering the second order wave drift motions play an important role. An introduction to this phenomenon is given and the effects which have to be taken into account are explained by means of a simple example where we can determine nearly all the aspects analytically. An interesting example that is worked out is the motion of very large floating flexible platforms with finite draft. Finally an introduction to the theory of shallow water non-linear dispersive waves is presented, and shallow water ship hydrodynamics, that plays a role in coastal areas and channels is treated. Here attention is paid to the interaction between passing ships in restricted water. In the appendix a short introduction to some of the mathematical tools is given.
