Water Environment Modeling
by Clark C.K. Liu Pengzhi Lin Hong XiaoWater Environment Modeling covers the formulations and applications of mathematical models that simulate water flow and chemical transport in rivers, lakes, groundwater, estuaries, coastal, and ocean waters. These models are used to evaluate the response of water environment to human interventions and serve as useful analytical tools for water pollution control and resource management. Simple and comprehensive modeling techniques and their practical applications are presented with examples and exercises, most of which are derived from actual case studies. In general, simple models can be solved analytically and comprehensive models require numerical solutions. While simple models are usually adopted for preliminary assessment of a particular water environment, comprehensive models are used to provide detailed spatial and temporal variations of pollutants in complex environments. The system-based models in the forms of integral equations are introduced as an alternative modeling approach. This textbook is ideal for advanced undergraduate students and graduate students in civil and environmental engineering and related academic fields. It is also suitable as a reference book for practicing engineers and scientists. Authors: Clark C.K. Liu is Emeritus Professor of the Department of Civil and Environmental Engineering at University of Hawaii and former Environmental Engineering Director of US National Science Foundation. Pengzhi Lin is Professor of State Key Laboratory of Hydraulics and Mountain River Engineering at Sichuan University. He is the author of Numerical Modeling of Water Waves (CRC Press, 2008). Hong Xiao is Professor and Vice Director of Hydroinformatics Institute of the State Key Laboratory of Hydraulics and Mountain River Engineering at Sichuan University.
The Water Environment of Cities
by Lawrence A. BakerUrbanization of the Earth's population will have increased the Earth's urban population from less than one billion in 1950 to five billion by 2030. Managing water for this burgeoning urban population is one of the critical needs for humanity. This book uses a holistic, interdisciplinary approach to examine the urban water environment. Water has multiple roles: municipal water supply, aquatic habitat, landscape aesthetics and recreation. Increasingly, urban water is reused, serving multiple purposes. Humans alter the urban hydrologic cycle and the chemical and physical integrity of urban water systems and resources. Some of those changes are beneficial, and others harmful. Understanding those changes and impacts requires expertise and perspective from a wide range of disciplines. Chapter authors represent this diversity of expertise, with expertise in surface and groundwater hydrology, civil and environmental engineering, environmental policy, urban planning, law, geomorphology, and recreation management.
Water Ethics: A Values Approach to Solving the Water Crisis (Earthscan Water Text)
by David GroenfeldtFully revised and updated, this second edition of Water Ethics continues to consolidate water ethics as a key dimension of water-related decisions. The book introduces the idea that ethics are an intrinsic dimension of any water policy, program, or practice, and that understanding what ethics are being acted out in water policies is fundamental to an understanding of water resource management. Alongside updated references and the introduction of discussion questions and recommended further reading, this new edition discusses in depth three significant developments since the publication of the first edition in 2013. The first is the growing awareness of the climate crisis as an existential threat, and associated concern about adaptive strategies for sustainable water management and ways of using water management for climate mitigation (e.g., practically through agricultural soil management and conceptually through ethics awareness). Second, there has been increased clarity among the religious community, Indigenous leaders, and progressive academics that ethics needs to become an arena for application and action (e.g., the Vatican encyclical Laudato Si, protests at Standing Rock and Flint, Michigan, in the US, and climate demonstrations worldwide). Thirdly, there have been new normative water standards ranging from "water stewardship" (industry initiative), water charters (Berlin) and the on-going initiative to develop a global water ethics charter. Drawing on case studies from countries including Australia, India, the Philippines, South Africa, and the United States, this textbook is essential reading for students of environmental ethics and water governance and management.

Water, Flood Management and Water Security Under a Changing Climate: Proceedings from the 7th International Conference on Water and Flood Management
by Anisul Haque Ahmed Ishtiaque Amin ChowdhuryThis book presents selected papers from the 7th International Conference on Water and Flood Management,with a special focus on Water Security under Climate Change, held in Dhaka, Bangladesh in March 2019. The biennial conference is organized by Institute of Water and Flood Management of Bangladesh University of Engineering and Technology. The recent decades have experienced more frequent natural calamities and it is believed that climate change is an important driving factor for such hazards. Each part of the hydrological cycle is affected by global climate change. Moreover, increasing population and economic activities are posing a bigger threat to water sources. To ensure sustainable livelihoods, safeguard ecosystem services, and enhance socio-economic development, water security needs to be investigated widely in a global and regional context.
Water Flow In Soils
by Tsuyoshi MiyazakiThe new edition of a bestseller, Water Flow in Soils bridges the fields of soil physics-where descriptions of water flow tend to be microscopic- and hydrology - where they tend to be macroscopic. Unlike other physics laden texts, this work conveys the fundamental concepts of water flow in soils with clear and essentially nonmathematical explanation
The Water, Food, Energy and Climate Nexus: Challenges and an agenda for action (Earthscan Studies in Natural Resource Management)
by Felix Dodds Jamie BartramGlobal trends of population growth, rising living standards and the rapidly increasing urbanized world are increasing the demand on water, food and energy. Added to this is the growing threat of climate change which will have huge impacts on water and food availability. It is increasingly clear that there is no place in an interlinked world for isolated solutions aimed at just one sector. In recent years the "nexus" has emerged as a powerful concept to capture these inter-linkages of resources and is now a key feature of policy-making. This book is one of the first to provide a broad overview of both the science behind the nexus and the implications for policies and sustainable development. It brings together contributions by leading intergovernmental and governmental officials, industry, scientists and other stakeholder thinkers who are working to develop the approaches to the Nexus of water-food-energy and climate. It represents a major synthesis and state-of-the-art assessment of the Nexus by major players, in light of the adoption by the United Nations of the new Sustainable Development Goals and Targets in 2015. With a foreword by HRH the Prince of Wales
The Water-Food-Energy Nexus: Processes, Technologies, and Challenges (Green Chemistry and Chemical Engineering)
by I. M. Mujtaba R. Srinivasan N. O. ElbashirExponential growth of the worldwide population requires increasing amounts of water, food, and energy. However, as the quantity of available fresh water and energy sources directly affecting cost of food production and transportation diminishes, technological solutions are necessary to secure sustainable supplies. In direct response to this reality, this book focuses on the water-energy-food nexus and describes in depth the challenges and processes involved in efficient water and energy production and management, wastewater treatment, and impact upon food and essential commodities. The book is organized into 4 sections on water, food, energy, and the future of sustainability, highlighting the interplay among these topics. The first section emphasizes water desalination, water management, and wastewater treatment. The second section discusses cereal processing, sustainable food security, bioenergy in food production, water and energy consumption in food processing, and mathematical modeling for food undergoing phase changes. The third section discusses fossil fuels, biofuels, synthetic fuels, renewable energy, and carbon capture. Finally, the book concludes with a discussion of the future of sustainability, including coverage of the role of molecular thermodynamics in developing processes and products, green engineering in process systems, petrochemical water splitting, petrochemical approaches to solar hydrogen generation, design and operation strategy of energy-efficient processes, and the sustainability of process, supply chain, and enterprise.
Water Footprint: Assessment and Case Studies (Environmental Footprints and Eco-design of Products and Processes)
by Subramanian Senthilkannan MuthuThis book highlights the concept of water footprint in different industrial sectors such as leather tanning, steel, agriculture, textile and wine. One of the very basic necessities of life which is soon going to be scarce is water, hence the environmental footprint assessments on any scale essentially includes water footprint which is being measured in various supply chains and across different product categories. According to ISO 14046, the water footprint assessment refers to the total freshwater volume consumed and polluted directly or indirectly across a product’s end-to-end supply chain. This book presents, for industry purposes, the focus on identification and quantification of water trade, the scarcity, and pollution involved in the production of goods and services.
Water Footprint Assessment: A Guide for Business (Doshorts Ser.)

Water for Agriculture: Irrigation Economics in International Perspective
by Stephen MerrettWorld population is set to increase by a third in the next 25 years, with no corresponding increase in global rainfall. About seventy per cent of the world's abstracted water is used in farming and therefore the economics of irrigation is becoming an increasingly important issue for sustainable development. Water for Agriculture provides a thorough
Water for Energy and Fuel Production (Green Chemistry And Chemical Engineering Ser. #17)
by Yatish T. ShahThis text describes water's use in the production of raw fuels, as an energy carrier (e.g., hot water and steam), and as a reactant, reaction medium, and catalyst for the conversion of raw fuels to synthetic fuels. It explains how supercritical water is used to convert fossil- and bio-based feedstock to synthetic fuels in the presence and absence of a catalyst. It also explores water as a direct source of energy and fuel, such as hydrogen from water dissociation, methane from water-based clathrate molecules, and more.
Water for Food Security and Well-being in Latin America and the Caribbean: Social and Environmental Implications for a Globalized Economy (Earthscan Studies in Water Resource Management)
by B Alberto Garrido M. RamThis volume provides an analytical and facts-based overview on the progress achieved in water security in Latin America and the Caribbean (LAC) region over during the last decade, and its links to regional development, food security and human well-being. Although the book takes a regional approach, covering a vast of data pertaining to most of the LAC region, some chapters focus on seven countries (Argentina, Brazil, Chile, Colombia, Costa Rica, Mexico and Peru). A full understanding of LAC’s trends progress requires framing this region in the global context: an ever more globalized world where LAC has an increasing geopolitical power and a growing presence in international food markets. The book’s specific objectives are: (1) exploring the improvements and links between water and food security in LAC countries; (2) assessing the role of the socio-economic ‘megatrends’ in LAC, identifying feedback processes between the region’s observed pattern of changes regarding key biophysical, economic and social variables linked to water and food security; and (3) reviewing the critical changes that are taking place in the institutional and governance water spheres, including the role of civil society, which may represent a promising means to advancing towards the goal of improving water security in LAC. The resulting picture shows a region where recent socioeconomic development has led to important advances in the domains of food and water security. Economic growth in LAC and its increasingly important role in international trade are intense in terms of use of natural resources such as land, water and energy. This poses new and important challenges for sustainable development. The reinforcement of national and global governance schemes and their alignment on the improvement of human well-being is and will remain an inescapable prerequisite to the achievement of long-lasting security. Supporting this bold idea with facts and science-based conclusions is the ultimate goal of the book.
Water for Life: Drinking Water, Health, Food, Energy Nexus
by A.W. JayawardenaWater is a precious resource essential for all forms of life, and although there is plenty of water to meet the demand for the present population – and even for a projected population of 9 billion – there is significant spatial and temporal variation in its distribution. This results in water rich and water poor countries, water-related conflicts, and unsafe drinking water, a major killer identified by the World Health Organization (WHO). Water for Life: Drinking Water, Health, Food, Energy Nexus covers these issues, highlighting the multi-facted uses and importance of water in life: water resources, chemistry of water, drinking water, and the links between water and health, food, irrigation, soil, energy, transport, industry, recreation, disasters, and conflicts. The book is accessible and clear, with technical elements. It is ideal as a background supplementary text to support more specialist study across civil engineering, geography, and social sciences, and will guide readers to see the big picture of environmentally sustainable water management for all human and other biotic lives.
Water Governance: Challenges and Prospects (Springer Water)
by Amarjit Singh Dipankar Saha Avinash C. TyagiThe book is the first of its kind to deal with almost the entire swath of water resources assessment, development and sustainable management. The idea of the book crystallized during the long journey of the Editors on various facets of water issues in India and abroad during their extended association, at all levels with the Ministry of Water Resources, River Development and Ganga Rejuvenation, as well as International Organizations dealing with water. Currently water-stressed, India is likely to become water scarce in not too distant a future. The global freshwater supply and its sustainable use for human consumption, and conservation of the ecosystem have never come under such a rigorous scrutiny before. The unplanned and reckless exploitation of this precious resource have led to a crisis situation, compounded by a real threat of climate change. This book is, therefore, timely and of particular relevance not only to India but the entire world. The book contains 20 chapters, beside the lead article by the Editors. The chapters are contributed by the eminent professionals, researchers, academicians and civil society representatives having an in-depth understanding of the issues. The contents of the chapters have been chosen to represent all aspects of water. The assessment of water resources using satellite data and in-depth analyses of groundwater sector like, the Aquifer Mapping Programme initiated by Government of India, application of gravity satellite data to assess the resource build up, artificial recharge of aquifers and its contamination, are dealt with by eminent experts. The articles on sustainable management of water through good governance by community participation and involvement of civil society are placed. Flood management both through a basin level approach as well as by building resilience in vulnerable areas is discussed. Other critical issues like water bodies management, constitutional provisions, water governance and financial issues, hydro-power and need of research and development in this sector are also dealt with aptly. In view of emerging crisis and complexities in this sector the future pathways and the paradigm shift that is required in administrative and policy level is also discussed.
Water Governance and Civil Society Responses in South Asia
by N. C. Narayanan S. Parasuraman Rajindra AriyabanduThis book addresses paradigm shifts in water policy and governance, and examines the role of civil society organizations in influencing public policy, while focusing on social equity and democratic participation. It illustrates a range of interesting developments in policy formulation, donor–state nexus, and interventions by civil society and voluntary organizations. The collection of articles provides a comprehensive and current narrative of the state–society relations in South Asia under neoliberal governance reforms, their implications and key responses with regard to water policies. Using case studies, it closely investigates the impact, effectiveness, drawbacks and challenges faced by voluntary organizations and social movements working at various levels in the water sector. The work will interest researchers and students of development studies, environmental studies, natural resource management, water governance, and public administration, as also water sector professionals, policymakers, civil society activists and governmental and non-governmental organizations.
Water Governance and Management in India: Issues and Perspectives, Volume 2 (Water Resources Development and Management)
by Girish Chadha Ashwin B. PandyaThis book, the second volume in the series, continues to raise contextual issues and presents perspectives regarding multifaceted challenges in management and governance of water in India. This volume attempts to broad base and expand the dialogue started in the first volume and would touch upon issues that need immediate discussion but have been left unattended like politics and management of groundwater, efficient utilization of water in agriculture (irrigation) and improving water use efficiency and building resilience. As in the first volume, this book presents a set of suggestions and recommendations in each chapter that can help frame policy guidelines in the country.
Water Governance, Policy and Knowledge Transfer: International Studies on Contextual Water Management (Earthscan Studies in Water Resource Management)
by Cheryl De Boer Joanne Vinke-de Kruijf Gül Özerol Hans BressersIn an increasingly global community of researchers and practitioners, new technologies and communication means have made the transfer of policies from one country or region to another progressively more prevalent. There has been a lot of attention in the field of public administration paid to policy transfer and institutional transplantation. This book aims to create a better understanding of such transfers in the water management sector. These include the adoption of modern water management concepts, such as integrated water resources management and forms of water governance, which are strongly promoted and sometimes also imposed by various international organizations. Transfers also occur within the scope of development aid or for the purpose of creating business opportunities. In addition, many research organisations, consultancies and governmental agencies are involved in cross-border work. The purpose of this book is therefore to present practical examples of the transfer of modern water management from one locality to another and to critically discuss the transferability of policy and governance concepts by analysing the contextual needs and factors. Case studies are included from North America, Europe, the Middle East and Asia. It is argued that in many cases context matters in water management and that there is no panacea or universal concept that can be applied to all countries or regions with different political, economic, cultural and technological contexts. Yet it is also shown that some countries are facing pressing and similar water management issues that cut across national borders, and hence the transfer of knowledge may be beneficial.
Water Harvesting in Sub-Saharan Africa
by William Critchley John GowingAgriculture in Sub-Saharan Africa is constrained by highly variable rainfall, frequent drought and low water productivity. There is an urgent need, heightened by climate change, for appropriate technologies to address this problem through managing and increasing the quantity of water on farmers’ fields – water harvesting. This book defines water harvesting as a set of approaches which occupy an intermediate position along the water-management spectrum extending from in situ moisture conservation to irrigated agriculture. They generally comprise small-scale systems that induce, collect, store and make use of local surface runoff for agriculture. The authors review development experience and set out the state of the art of water harvesting for crop production and other benefits in Sub-Saharan Africa. This includes an assessment of water harvesting schemes that were initiated two or three decades ago when interest was stimulated by the droughts of the 1970s and 1980s. These provide lessons to promote sustainable development of dryland agriculture in the face of changing environmental conditions. Case studies from eight countries across Sub-Saharan Africa provide the evidence base. Each follows a similar format and is based on assessments conducted in collaboration with in-country partners, with a focus on attempts to promote adoption of water harvesting, both horizontally (spread) and vertically (institutionalization). Introductory cross-cutting chapters as well as an analytical conclusion are also included.
Water Histories and Spatial Archaeology
by Michael J. HarrowerThis book offers a new interpretation of the spatial-political-environmental dynamics of water and irrigation in long-term histories of arid regions. It compares ancient Southwest Arabia (3500 BC–AD 600) with the American West (2000 BC–AD 1950) in global context to illustrate similarities and differences among environmental, cultural, political, and religious dynamics of water. It combines archaeological exploration and field studies of farming in Yemen with social theory and spatial technologies, including satellite imagery, Global Positioning System (GPS), and Geographic Information Systems (GIS) mapping. In both ancient Yemen and the American West, agricultural production focused not where rain-fed agriculture was possible, but in hyper-arid areas where massive state-constructed irrigation schemes politically and ideologically validated state sovereignty. While shaped by profound differences and contingencies, ancient Yemen and the American West are mutually informative in clarifying human geographies of water that are important to understandings of America, Arabia, and contemporary conflicts between civilizations deemed East and West.
Water Hyacinth: A Potential Lignocellulosic Biomass for Bioethanol
by Anuja Sharma Neeraj K. AggarwalThis book discusses the production of bioethanol from water hyacinth, a potential source of lignocellulosic biomass. Biofuels, as an alternative to fossil fuels, not only ensure energy security but also mitigate air pollution and reduce greenhouse emissions. Biofuels can be produced from sugar- and starch-rich food crops (first-generation biofuel) or lignocellulosic biomass (second-generation biofuel). However, the overexploitation of conventional lignocellulosic sources such as agro-industrial residues, dedicated herbaceous, hardwoods and softwoods and forest residues may lead to problems in terms of land management and biodiversity conservation. Non-conventional sources include industrial cellulosic waste, municipal solid waste and weeds. Of these, weeds are an attractive lignocellulosic source due to their prevalence and easy availability. Eichhornia crassipes, commonly known as water hyacinth, is one of the world’s most invasive weeds due to its rapid proliferation rate, efficient survival strategies in extreme conditions, and it has a significant impact on the environment, ecological communities, human health and socioeconomic development. Strategies including physical removal, chemical methods and biological control agents have proven inefficient in completely eradicating Eichhornia crassipes. On the other hand, water hyacinth has a low lignin and high holocellulose content and is a rich source of lignocellulosic biomass, and has therefore been exploited as a raw material for the production of biofuel, biogas, animal and fish feed, compost and other valuable products. Further, being an aquatic plant, it does not compete with food crops for land resources. The bioethanol-generating capacity of water hyacinth is comparable to that of agricultural waste, making it a potential raw material for biofuel production.

Water Hydraulics Control Technology
by Erik TrostmannThis work introduces the principles of water hydraulics technology and its benefits and limitations, and clarifies the essential differences between water and oil hydraulics. It discusses basic components and systems, including hydraulic power generators (pumps), hydraulic control components or modulators (valves), hydraulic transmission lines (tubes, hoses and fittings) and hydraulic actuators (single- or double-acting cylinders and rotary motors). A listing of water hydraulics components/systems manufacturers is provided.
Water in Biomechanical and Related Systems (Biologically-Inspired Systems #17)
by Adam GadomskiThe contributed volume puts emphasis on a superior role of water in (bio)systems exposed to a mechanical stimulus. It is well known that water plays an extraordinary role in our life. It feeds mammalian or other organism after distributing over its whole volume to support certain physiological and locomotive (friction-adhesion) processes to mention but two of them, both of extreme relevance.Water content, not only in the mammalian organism but also in other biosystems such as whether those of soil which is equipped with microbiome or the ones pertinent to plants, having their own natural network of water vessels, is always subjected to a force field.The decisive force field applied to the biosystems makes them biomechanically agitated irrespective of whether they are subjected to external or internal force-field conditions. It ought to be noted that the decisive mechanical factor shows up in a close relation with the space-and-time scale in which it is causing certain specific phenomena to occur.The scale problem, emphasizing the range of action of gravitational force, thus the millimeter or bigger force vs. distance scale, is supposed to enter the so-called macroscale approach to water transportation through soil or plants’ roots system. It is merely related to a percolation problem, which assumes to properly inspect the random network architecture assigned to the biosystems invoked. The capillarity conditions turn out to be of prior importance, and the porous-medium effect has to be treated, and solved in a fairly approximate way.The deeper the scale is penetrated by a force-exerting and hydrated agent the more non-gravitational force fields manifest. This can be envisaged in terms of the corresponding thermodynamic (non-Newtonian) forces, and the phenomena of interest are mostly attributed to suitable changes of the osmotic pressure. In low Reynolds number conditions, thus in the (sub)micrometer distance-scale zone, they are related with the corresponding viscosity changes of the aqueous, e.g. cytoplasmatic solutions, of semi-diluted and concentrated (but also electrolytic) characteristics. For example, they can be observed in articulating systems of mammals, in their skin, and to some extent, in other living beings, such as lizards, geckos or even insects. Through their articulating devices an external mechanical stimulus is transmitted from macro- to nanoscale, wherein the corresponding osmotic-pressure conditions apply.The content of the proposed work can be distributed twofold. First, the biomechanical mammalian-type (or, similar) systems with extraordinary relevance of water for their functioning will be presented, also including a presentation of water itself as a key physicochemical system/medium. Second, the suitably chosen related systems, mainly of soil and plant addressing provenience, will be examined thoroughly. As a common denominator of all of them, it is proposed to look at their hydrophobic and/or (de)hydration effects, and how do they impact on their basic mechanical (and related, such as chemo-mechanical or piezoelectric, etc.) properties. An additional tacit assumption employed throughout the monograph concerns statistical scalability of the presented biosystems which is equivalent to take for granted a certain similarity between local and global system’s properties, mostly those of mechanical nature. The presented work’s chapters also focus on biodiversity and ecological aspects in the world of animals and plants, and the related systems. The chapters’ contents underscore the bioinspiration as the key landmark of the proposed monograph.
