The thermal use of the shallow subsurface is increasingly being promoted and implemented as one of many promising measures for saving energy. A series of questions arises concerning the design and management of underground and groundwater heat extraction systems, such as the sharing of the thermal resource and the assessment of its long-term potential. For the proper design of thermal systems it is necessary to assess their impact on underground and groundwater temperatures. Thermal Use of Shallow Groundwater introduces the theoretical fundamentals of heat transport in groundwater systems, and discusses the essential thermal properties. It presents a complete overview of analytical and numerical subsurface heat transport modeling, providing a series of mathematical tools and simulation models based on analytical and numerical solutions of the heat transport equation. It is illustrated with case studies from Austria, Germany, and Switzerland of urban thermal energy use, and heat storage and cooling. This book gives a complete set of analytical solutions together with MATLAB(r) computer codes ready for immediate application or design. It offers a comprehensive overview of the state of the art of analytical and numerical subsurface heat transport modeling for students in civil or environmental engineering, engineering geology, and hydrogeology, and also serves as a reference for industry professionals.

One of the major problems facing practitioners and scientists working with water management is how to integrate knowledge and experiences from scientific, policy and stakeholder perspectives. In this book this science-policy-stakeholder interface (SPSI) is examined both analytically and through the description of practical experiences from river basins in Europe, India and South-East Asia. These include the Tungabhadra (India), Sesan (Vietnam/Cambodia), Tagus (Spain/Portugal) and Glomma (Norway), which particularly highlight issues associated with pollution, severely altered river flows and transboundary conflicts. Following two chapters which lay the framework for the book the authors describe how SPSI was managed in the case study basins and how stakeholder participation and scenarios were used to integrate different perspectives, and to facilitate the communication of different forms of knowledge. Four important aspects of water management and SPSI are then discussed; these are water pollution, land and water interaction, environmental flow and transboundary water regimes. Short descriptions of the case study rivers are provided together with analyses of how SPSI was managed in water management in these basins and policy recommendations for the basins. The book concludes by providing a series of recommendations for improving the science-policy-stakeholder interface in water management. It represents a major step forward in our understanding of how to implement integrated water resources management.

This book is an outcome from the International Expo 'Water and Sustainable Development' held in Zaragoza (Spain) in 2008. Support from the Spanish Ministry of Environment, Caja Rioja, Government of Aragon, and the World Bank is acknowledged. 'Few resources will play a more important role in shaping our economic future, or face more daunting challenges, than water. This internationally acclaimed team of experts has produced a first-rate volume that is full of intriguing, practical ideas for meeting those challenges in a rich variety of institutional settings.' Tom Tietenberg, Mitchell Family Professor of Economics, Emeritus, Colby College, USA 'This volume brings together two critical but interrelated dimensions of water challenge, i.e. water pollution, particularly from non-point sources, and water conservation. The editors are well known experts on the subject as are the contributors.' R. Maria Saleth, International Water Management Institute, Sri Lanka and Associate Editor, Water Policy 'The profound contribution of this volume is that it brings together various economic concepts and policy dilemmas regarding water shortages, non-point source pollution, efficiency of water use and irrigation technology. Recommended reading for anyone working in the area of water management.' Henk Folmer, University of Groningen and Wageningen University, The Netherlands As countries face deteriorating water and environmental quality as well as water shortages, pollution control and the efficiency of water use become of paramount importance. Agriculture is one of the main non-point polluters of water bodies and irrigation for agriculture is one of the main consumers of water. While it is very hard to regulate pollution from agriculture, attempts have been made via economic and command and control instruments, and also through investments in technologies and ecosystems recovery. Coping with non-point pollution takes the form of both policy intervention and technology development. Likewise it is recognized that irrigation efficiency varies across countries, influenced by both technology and supporting adoption policies. Countries that lead in irrigation technology and supporting policies have certain traits in common. They face very high scarcity and are pushed to find innovative solutions, both technical and policy related. The recent multibillion investments in irrigation technologies in Spain, and similar proposals in Australia, for example, highlight the potential of irrigation technologies to cope with scarcity and water quality degradation. This book reviews all of the above issues, presents experiences in selected countries, and assesses the degree of success of alternative policies for coping with non-point water pollution and improving irrigation efficiency.

Examining international water allocation policies in different parts of the world, this book suggests that they can be used as a platform to induce cooperation over larger political issues, ultimately settling conflicts. The main premise is that water can and should be used as a catalyst for peace and cooperation rather than conflict. Evidence is provided to support this claim through detailed case studies from the Middle East and the Lesotho Highlands in Africa. These international cases - including bilateral water treaties and their development and formation process and aftermath - are analyzed to draw conclusions about the outcomes as well as the processes by which these outcomes are achieved. It is demonstrated that the perception of a particular treaty as being equitable and fair is mainly shaped by the negotiation process used to reach certain outcomes, rather than being determined mechanistically by the quantitative allocation of water to each party. The processes and perceptions leading to international water conflict resolutions are emphasized as key issues in advancing cooperation and robust implementation of international water treaties. The key messages of the book are therefore relevant to the geo-political and hydro-political aspects of water resources in the context of bilateral and multilateral conflicts, and the trans-boundary management of water resources, which contributes insights to political ecology, geo-politics, and environmental policy.

Examining the water, development and security linkages in Central Asia can feel a bit like solving a Rubik's cube. The Rubik's cube starts to usually find structure and the different pieces find their places when its solver adopts a systematic approach. Still, solving the whole cube takes time and perseverance. This is also the case with water and security in Central Asia as demonstrated by the chapters in this book. In the case of water and security in Central Asia, there are many "faces", including not only the Central Asian states but also the neighbouring countries and other players of global geopolitics; "stickers" such as policies, practices, causes, and impacts; and "colours" such as the different stakeholders, ranging from the micro and meso levels to the macro level. Understanding all these, or getting clarity on the nexus, can seem extremely challenging. Even though none of the chapters alone answers the question of what constitutes water and security in Central Asia, each of them gives thoughtful ideas and information on the complexity of the issue. This book was published as a special issue of the International Journal of Water Resources Development.

A combination of future change pressures - including unprecedented growth in population, urbanization, socio-economic, and climate change - are imposing new stresses on the earth s resources and society s ability to maintain or improve infrastructure systems and environmental quality. While planning for sustainability, we need to make decisions considering those future change pressures, which are often uncertain and generate various risks in systems. These decisions determine the long-term sustainability of a system. The main outcomes of this research are a novel framework for risk and uncertainty analysis, a hybrid approach of uncertainty analysis, and fuzzy set theory based multi-criteria analysis method for decision-making.

The developed framework can be applied in any other system without much modification. The algorithms for a hybrid approach to uncertainly analysis are based on both the probability and fuzzy set theory. It can capture both qualitative and quantitative sources of uncertainty in any complex system modelling. The fuzzy set theory based multi-criteria analysis method is supported with a framework that allows quantifying performance and sustainability in a system. Both uncertainty analysis and multi-criteria methods are supported with stand-alone tools that can be coupled with any systems modelling.

The framework, methods, and tools are demonstrated in data surplus case in Birmingham, UK and data scarce case in Kathmandu, Nepal and Mbale Town, Uganda. This thesis demonstrates the effectiveness of the developed framework, methodology, and tools for strategic planning of urban water systems in both data scarce and data limited conditions.

The principle of transferable groundwater rights is that by making water rights capable of being traded in the market, water resources can be used more sustainably and efficiently. Groundwater would achieve its economic value, by switching from the high volume-low value irrigation, which is prevalent with many farmers, particularly in South Asia, to low volume-high value urban supply or the growing of intensive horticultural or cash crops. This book discusses transferable groundwater rights in their broader context. It starts with a detailed description of the physical aspects of groundwater, which non-technical readers should find useful, followed by a discussion of legal and economic aspects. Water transfers and the international experiences in transferable groundwater rights are dealt with in detail in two subsequent chapters. A model is presented to guide those involved in water resources management and planning in their decision process to introduce transferable groundwater rights and water rights trading. The author concludes that transferable groundwater rights potentially offer a better alternative to land-based water rights systems. However, he casts serious doubt on whether groundwater rights trading on its own can achieve water resources sustainability, environmental protection and social equity. Government intervention seems to be almost always needed to assist the water rights market and take responsibility for any of its adverse consequences.

Watermaths presents the mathematics underpinning the design and operation of the individual unit process technologies used for purifying water and wastewater. The book aims to provide the reader with sufficient information to enable them to tackle the most important calculations in this area, without requiring any prior knowledge of the subject and assuming only a very basic grounding in science or engineering. It focuses on the most essential areas of knowledge required, containing tuition in basic numeracy, chemistry, process engineering and fluid physics, as well as cost analysis. The simple and succinct delivery is designed to get the reader up to speed as rapidly as possible: sufficient background information is provided to explain the purpose of the calculations, and ultimately tackle the complete wastewater reclamation plant design problem included in the book. Example calculations are provided within each chapter, each followed by exercises intended to reinforce the learning (and for which solutions are appended). Exercises range in difficulty from simple single calculational-step problems to more complex ones, and the over-arching design problem provides some context to the mathematics. The book can be understood by those relatively new to the water sector, and is intended as a primer rather than a comprehensive handbook. It is nonetheless sufficiently comprehensive to permit design calculations for most water and wastewater treatment unit processes. Core disciplines covered include: * manipulation of equations, including logarithmic and exponential expressions * fluid physics for describing flow through pipes, channels and filters * chemical concentrations and chemical/biochemical reactions * chemical/biochemical reaction kinetics * mass balance for determining fate of materials through unit processes * mass transfer for determining transfer of materials across boundaries within processes * reactor theory for designing biochemical and chemical reaction vessels * cost analysis, including capital and operating expenditure with discounting. New to the third edition: * new chapter on cost analysis * further explanation of the classical unit operations types * illustrations expanded to include unit operation schematics and symbols * new examples and exercises * updated design problem. Watermaths ... just add water.

By 2025, two thirds of the world's population will be living in water stressed conditions. Meanwhile, the degradation of water ecosystems is occurring at alarming rates. Water utilities and water regulators that choose to play an active role in catchment management with nature based solutions (NBS) are uniquely positioned to help. Building a robust knowledge base and supporting opportunities for cross-sector collaboration are fundamental to the mainstreaming of NBS. The International Water Association (IWA) and The Nature Conservancy (TNC) are working together to encourage and facilitate active utility involvement in NBS, as well as promoting stronger connections between water utilities and regulatory bodies. Implementation of NBS involves multiple, interdependent stakeholders at various governance levels, and consequently regulators a key role in creating the enabling environments for these interactions and negotiations. This publication taps into diverse geographies and contexts, delving into case studies for a richer conversation that addresses the variety of challenges and elements for success for integrating NBS into water utility operations and planning. By publicizing successful case studies, the IWA/TNC partnership fulfils a dual purpose of endorsing these efforts and providing actionable guidance for other water utilities striving to improve their sustainability and resiliency.

The study presented in this book is a part of a collective effort to bridge the existing gap of our understanding of morphological behavior of tidal basins between engineering and geological time scales by extending the use of coastal engineering tools (process-based models) to geological time scales. The Dutch Waddenzee is chosen as the case study and the working hypothesis that 'If you put enough of the essential physics into the model, the most important features of the morphological behavior will come out, even at longer time scales' is examined. Through a number of steps, this study shows that the working hypothesis is valid and provides a clearer picture of the relation between 'most important features ' and ' the essential physics '. In this study it is shown that a process-based model can be used to simulate long-term morphological changes in tidal basins and produce reasonable results. The result of a very simplified model of the Dutch Waddenzee shows a good qualitative agreement with current pattern of channels and shoals of the Dutch Waddenzee. Also the morphological features of the basins in the simulations follow the data-based equilibrium equations and conceptual models.

One of the most challenging aspects of climate change has been the increased pressure on water resources limited by droughts and new rain patterns, which has been exacerbated by rapid modernization. Due to these realities, disputes across national borders over use and access to water have now become more commonplace. This study analyzes the history and adjudication of transboundary water disputes in five international courts and tribunals, two US Supreme Court cases, and boundary water disputes between the United States and Canada and the United States and Mexico. Explaining the circumstances and outcomes of these cases, Kornfeld asks how effective the courts and tribunals have been in adjudicating them. What kind of remedies have they fashioned and how have they dealt with polycentric and sovereignty issues? This timely work examines the doctrine of equitable allocation of transboundary water resources and how this norm can be incorporated into international law.

Water quality standards across the world are being re-written to promote healthier ecosystems, ensure safe potable water sources, increased biodiversity, and enhanced ecological functions. Treatment wetlands are used for treating a variety of pollutant waters, including municipal wastewater, agricultural and urban runoff, industrial effluents, and combined sewer overflows, among others. Treatment wetlands are particularly well-suited for sustainable water management because they can cope with variable influent loads, can be constructed of local materials, have low operations and maintenance requirements compared to other treatment technologies, and they can provide additional ecosystem services. The technology has been successfully implemented in both developed and developing countries. The first IWA Scientific and Technical Report (STR) on Wetland Technology was published in 2000. With the exponential development of the technology since then, the generation of a new STR was facilitated by the IWA Task Group on Mainstreaming Wetland Technology. This STR was conceptualized and written by leading experts in the field. The new report presents the latest technology applications within an innovative planning framework of multi-purpose wetland design. It also includes practical design information collected from over twenty years of experience from practitioners and academics, covering experiments at laboratory and pilot-scale up to full-scale applications.

Floods are one of the most common and widely distributed natural risks to life and property worldwide. There is a need to identify the risk of flooding in flood prone areas to support decisions for flood management from high level planning proposals to detailed design. An important part of modern flood risk management is to assess vulnerability to floods. This assessment can be done only by using a parametric approach. Worldwide there is a need to enhance our understanding of vulnerability and to also develop methodologies and tools to assess vulnerability. One of the most important goals of assessing flood vulnerability is to create a readily understandable link between the theoretical concepts of flood vulnerability and the day-to-day decision-making process and to encapsulate this link in an easily accessible tool. The present book portrays a holistic parametric approach to be used in flood vulnerability assessment and this way to facilitate the consideration of system impacts in water resources decision-making. The approach was verified in practical applications on different spatial scales and comparison with deterministic approaches. The use of flood vulnerability approach can produce helpful understanding into vulnerability and capacities for using it in planning and implementing projects.

This study investigates the patterns that describe reliability of water distribution networks focusing to the node connectivity, energy balance, and economics of construction, operation and maintenance. A number of measures to evaluate the network resilience has been developed and assessed to arrive at more accurate diagnostics of regular and irregular demand scenarios. These measures have been proposed as a part of the methodology for snap-shot assessment of network reliability based on its configuration and hydraulic performance. Practical outcome of the research is the decision support tool for reliability-based design of water distribution networks. This computer package named NEDRA (NEtwork Design and Reliability Assessment) consists of the modules for network generation, filtering, initialisation, optimisation, diagnostics and cost calculation, which can be used for sensitivity analyses of single network layout or assessments of multiple layouts. The study concludes that none of the analysed aspects develops clear singular patterns. Nevertheless, the proposed network buffer index (NBI) and the hydraulic reliability diagram (HRD) as visual representation of the network resilience give sufficient snap-shot pointing the composition of the index value, and displaying possible weak points in the network that can be hidden behind the averaged values of various reliability measures.

Prediction of microbial transport distances are usually based on the sticking efficiency, a parameter in the classical colloid filtration theory. This parameter represents the interaction between colloid and collector surfaces resulting in deposition. According to the theory, the sticking efficiency is invariable when physico-chemical characteristics of aquifer media are homogeneous. However, many research results have indicated variations within bacterial strains. In this research, the transport of Escherichia Coli in saturated quartz columns were conducted in the laboratory. The objectives were to characterise the distribution of sticking efficiency, measure low sticking efficiency values of cells, and to develop a methodology to measure minimum values of sticking efficiencies within bacterial sub-populations. Also, the work assesses the contribution of phenotypic and genotypic characteristics of Escherichia coli on their attachment to quartz grains.

A multitude of processes in hydrology and environmental engineering are either random or entail random components which are characterized by random variables. These variables are described by frequency distributions. This book provides an overview of different systems of frequency distributions, their properties, and applications to the fields of water resources and environmental engineering. A variety of systems are covered, including the Pearson system, Burr system, and systems commonly applied in economics, such as the D'Addario, Dagum, Stoppa, and Esteban systems. The latter chapters focus on the Singh system and the frequency distributions deduced from Bessel functions, maximum entropy theory, and the transformations of random variables. The final chapter introduces the genetic theory of frequency distributions. Using real-world data, this book provides a valuable reference for researchers, graduate students, and professionals interested in frequency analysis.
