This volume provides readers with an opportunity to learn from front line water managers of watershed-based agencies across Canada about integrated water management (or integrated water resource management). In common with practice in much of the world, the responsibility for implementing integrated watershed management in Canada is fragmented. Each province and territory in Canada has developed unique approaches or governance models to guide decision making in that regard. Thus, this edited volume enables readers from around the world to gain insight on the best practices in Canada for achieving success and addressing barriers to implement IWM. Although there remains non consensus about how to "best" approach river basin management, some of the main observations include: There is a need to balance a focus on "the big picture", with scoping the scale and scope of planning activities in order that feasible and effective solutions can be implemented Three types of integration are popular among the agencies included in the book: (i) among environment, economy and society, (ii) interactions between people and the environment and (iii) integration (or coordination) of administrative activities. Much more attention is required to achieving effective engagement from Indigenous communities The chapters were originally published in a special issue of the International Journal of Water Resources Development.

A comprehensive and detailed study on the scaling potential of calcium carbonate in seawater reverse osmosis systems (SWRO), this book provides a new approach for calculating the degree of supersaturation and the pH of the SWRO systems concentrates with the assistance of the feed-water pH and the inorganic carbon constituents. Furthermore, the book highlights the weakness in the present supersaturation indices and membrane manufacturers programs. Finally, the research suggested that SWRO concentrate is much lower undersaturated with respect to calcium carbonate than previously thought. This was confirmed by comprehensive pilot testing where acids and antiscalants used to prevent calcium carbonate scaling were completely eliminated from the pilot plant.

This volume in the Fundamentals for the Water and Wastewater Main Operator series covers the basics of piping and valves in water and wastewater plants, including details on fittings, strainers, filters, traps and control systems. The book explains how pipes and valves are used to feed materials (e.g., chemicals) into influents and effluents and siphon off unwanted liquid and gaseous by-product. Also covered is how pipes are developed into systems and subsystems and coordinated into a plant-wide functioning unit.

Environmental Fluid Mechanics (EFM) studies the motion of air and water at several different scales, the fate and transport of species carried along by these fluids, and the interactions among those flows and geological, biological, and engineered systems. EFM emerged some decades ago as a response to the need for tools to study problems of flow and transport in rivers, estuaries, lakes, groundwater and the atmosphere; it is a topic of increasing importance for decision makers, engineers, and researchers alike. The second edition of the successful textbook "Fluid Mechanics of Environmental Interfaces" is still aimed at providing a comprehensive overview of fluid mechanical processes occurring at the different interfaces existing in the realm of EFM, such as the air-water interface, the air-land interface, the water-sediment interface, the surface water-groundwater interface, the water-vegetation interface, and the water-biological systems interface. Across any of these interfaces mass, momentum, and heat are exchanged through different fluid mechanical processes over various spatial and temporal scales. In this second edition, the unique feature of this book, considering all the topics from the point of view of the concept of environmental interface, was maintained while the chapters were updated and five new chapters have been added to significantly enlarge the coverage of the subject area. The book starts with a chapter introducing the concept of EFM and its scope, scales, processes and systems. Then, the book is structured in three parts with fifteen chapters. Part one, which is composed of four chapters, covers the processes occurring at the interfaces between the atmosphere and the surface of the land and the seas, including the transport of dust and the dispersion of passive substances within the atmosphere. Part two deals in five chapters with the fluid mechanics at the air-water interface at small scales and sediment-water interface, including the advective diffusion of air bubbles, the hyporheic exchange and the tidal bores. Finally, part three discusses in six chapters the processes at the interfaces between fluids and biotic systems, such as transport processes in the soil-vegetation-lower atmosphere system, turbulence and wind above and within the forest canopy, flow and mass transport in vegetated open channels, transport processes to and from benthic plants and animals and coupling between interacting environmental interfaces. Each chapter has an educational part, which is structured in four sections: a synopsis of the chapter, a list of keywords that the reader should have encountered in the chapter, a list of questions and a list of unsolved problems related to the topics covered by the chapter. The book will be of interest to graduate students and researchers in environmental sciences, civil engineering and environmental engineering, (geo)physics, atmospheric science, meteorology, limnology, oceanography, and applied mathematics.

Worldwide, many regions have a great potential to cover part of their pressing water needs by renewable energy powered water treatment processes using either thermal or membrane based technologies. Not only arid and semiarid regions are increasingly suffering from water shortage but also many other regions face a limitation of freshwater resources either by increasing contamination of surface water bodies or groundwater resources unsuitable for drinking and irrigation purposes either due to their high grade of mineralization or their contents of toxic components. In many areas without centralized water supply, treatment techniques using locally available renewable energy resources such as wind, solar and geothermal can provide an economical, social and environmentally sustainable option for clean water production from seawater and from highly mineralized or otherwise unsuitable ground- and surface water. This book provides an overview on possible cost-efficient techniques and application opportunities for different scales and shows why the implementation of these technologies faces numerous technological, economic and policy barriers and provides suggestions how they can be overcome. It serves as a synoptic compendium of the fundamentals of freshwater production using renewable energies, applicable to all types of water, ranging from brackish to marine water and also including industrial and communal residual water. The book is aimed at professionals, academics and decision makers worldwide, working in the areas of water resources, water supply,land planning, energy planning, greenhouse gases emission mitigation and rural development.

Primarily written as course material on flood control and drainage engineering for advanced students of civil engineering, this new fourth edition is again thoroughly revised. It accommodates recent developments in remote sensing, information technology and GIS technology. New added material deals with flood management due to Tsunami waves, flooding due to dam failure and breaking of embankments, application of dredging technologies, problems of flood forecasting, flood plain prioritization and flood hazard zoning, and engineering measures for flood control. Drainage improvement is tackled, with particular regard to salinity and coastal aquifer management from the ingress of sea water. The book includes design problem-solving and case studies, making it practical and applications-oriented. The subject matter will be of considerable interest to civil engineers, agricultural engineers, architects and town planners, as well as other government and non-government organizations.

Pipe failures in water distribution systems can have a serious impact and hence it's important to maintain the condition and integrity of the distribution system. This book presents a whole-life cost optimisation model for the rehabilitation of water distribution systems. It combines a pipe breakage number prediction model with a pipe criticality assessment model, which enables the creation of a well-constructed and more tightly constrained optimisation model. The pipe breakage number prediction model combines information on the physical characteristics of the pipes with historical information on breakage and failure rates. A weighted multiple nonlinear regression analysis is applied to describe the condition of different pipe groups. The criticality assessment model combines a pipe's condition with its hydraulic significance through a modified TOPSIS. This model enables the optimisation to focus its efforts on those important pipes. The whole life cost optimal rehabilitation model is a multiple-objective and multiple-stage model, which provides a suite of rehabilitation decisions that minimise the whole life cost while maximising its long-term performance. The optimisation model is solved using a modified NSGA-II. The utility of the developed models is that it allows decision makers to prioritize their rehabilitation strategy in a proactive and cost-effective manner.

This monograph provides a framework and guidelines for the assessment of institutional frameworks for integrated water resources management (IWRM). The framework and guidelines were developed to enable expert teams of the Inter-American Development Bank to incorporate capacity-building considerations into water-related projects. The framework and guidelines were tested in four countries with different physical, social and economic environments in Latin America and the Caribbean. Using this framework, it is possible to identify shortcomings in existing water management arrangements and to formulate interventions at and between the constitutional, organizational, and operational levels. To guide the formulation of interventions, an ideal IWRM situation is formulated. Due to the temporal and spatial specificity, a desired IWRM situation is formulated in a process which consists of ten operational steps. This process is based on an extensive consultation and participation of all relevant stakeholders. The fields of interventions concern awareness creation, policy development, legal and financial arrangements, human resources development and management information and decision support systems.

The Niger delta with its gentle slope and low elevation is extremely sensitive to effects of climate change. Its adaptive capacity is the second lowest in terms of socio-economic development in Nigeria. Quantitative studies on developing measures for coastal planning and management in the lower Niger delta have been limited by data availability and inaccessibility of parts of the delta. The use of satellite data can help bridge the data gap by providing ancillary data (imagery, elevation, altimetry etc.) that can be used to quantify the effects of SLR in the Niger delta. This thesis uses satellite data as the main source for hydrodynamic modelling and GIS analysis. Until recently such data might not have the accuracy and precision of directly measured data. However recent innovative approaches have enabled better exploitation of satellite data to overcome these limitations and produce adequate results to assess the impact of SLR on the Niger delta in an integrated way that will lead to practical recommendations for adaptation. Using projected global eustatic SLR values in combination with land subsidence, this thesis estimated SLR levels for the Niger delta and its effect on inundation areas and flood extent. The results indicate that the Niger delta is very vulnerable to inundation and that even minimal SLR will affect flooding in the lower Niger delta since the area continues to subside. A new coastal vulnerability index was developed in this thesis by evaluating physical, social and human influence indicators of exposure, susceptibility and resilience. The results show that parts of the Niger delta are highly vulnerable to SLR and need adequate mitigation/adaptation measures to protect them. It is recommended that sustainable local resilience practices already being used in parts of the Niger delta should be included in adaptation planning.

Demand for land and water for agriculture, urbanization, irrigation, hydropower, and industrialization is increasing to meet the demands of growing populations and of growing economies. However, changes in land and water resources are often studied separately. A better representation of the interaction between land-use change and its drivers on the one hand and water resources on the other is imperative for sustainable environmental management. This research investigates and develops spatial analysis methods and tools for the quantification of dynamic feedbacks between land-use change and water resources, by focusing on case study catchments in Ethiopia and South Africa. Furthermore, the research investigates methods for analysing land-use suitability and modelling land-use change. Results show that major changes in land-use have been observed in the past two to three decades in the study catchments. Model representation of the interaction between land-use change and water resources shows that changes in land-use influence hydrologic responses. These influences are especially pronounced during high- and low-flow seasons. Likewise, hydrologic processes and water resources availability influence land-use suitability and hence land-use change responses. Accounting for the dynamic feedback between land-use and hydrology thus produces improved knowledge that can better inform integrated natural resources management.

The world's fresh water supplies are dwindling rapidly-even wastewater is now considered an asset. By 2025, most of the world's population will be facing serious water stresses and shortages. Aquananotechnology: Global Prospects breaks new ground with its informative and innovative introduction of the application of nanotechnology to the remediation of contaminated water for drinking and industrial use. It provides a comprehensive overview, from a global perspective, of the latest research and developments in the use of nanotechnology for water purification and desalination methods. The book also covers approaches to remediation such as high surface area nanoscale media for adsorption of toxic species, UV treatment of pathogens, and regeneration of saturated media with applications in municipal water supplies, produced water from fracking, ballast water, and more. It also discusses membranes, desalination, sensing, engineered polymers, magnetic nanomaterials, electrospun nanofibers, photocatalysis, endocrine disruptors, and Al13 clusters. It explores physics-based phenomena such as subcritical water and cavitation-induced sonoluminescence, and fog harvesting. With contributions from experts in developed and developing countries, including those with severe contamination, such as China, India, and Pakistan, the book's content spans a wide range of the subject areas that fall under the aquananotechnology banner, either squarely or tangentially. The book strongly emphasizes sorption media, with broad application to a myriad of contaminants-both geogenic and anthropogenic-keeping in mind that it is not enough for water to be potable, it must also be palatable.

This book forms the proceedings of the 18th European ICID conference on irrigation and drainage. Water is not a free commodity and demand is becoming more and more intense for its allocation. This book focuses on the role of irrigation and drainage in the debate on water and should be of interest to planners, designers, policy makers in the water industry, national and local government, academic researchers and environment agencies.

More than a billion people cannot get safe drinking water; half the world's population does not have adequate sanitation; within a generation over three billion will be suffering from water stress. This text analyzes the issues in this crisis of management and shows how water can be used effectively and productively. The key to sustainable water resources is an integrated approach. The authors assert that careful planning and concerted action can make the fundamental changes needed and that the implications of not dealing with the crisis are immense. The book comes with downloadable resources containing background research and scenarios.

This book is a compilation of the papers presented at the Twenty-Ninth Mid-Atlantic Industrial and Hazardous Waste Conference. It helps people to move a step closer to the acceptable balance of costs, benefits, and risks in their attempts to resolve industrial and hazardous waste problems.

Conflicts over waste disposal facility siting is a pressing issue not only in developed countries but also in fast-growing countries that face drastic waste increase and rapid urbanisation. How to address distributive justice has been one of the biggest concerns. This book examines what determines the influence of distributive justice in siting policy. In the 23 wards of Tokyo, one idea of distributive justice, known as "In-Ward Waste Disposal" (IWWD), emerged amid the ongoing garbage crisis in the early 1970s. IWWD was adopted as a significant principle, but its influence waxed and waned over time, until the idea was finally abandoned in 2003. To unravel causes and mechanisms behind the changing influence of IWWD, this book adopts a framework that considers not only ideational causes, but also the power struggles between rationally calculating actors, as well as the influence of external events and environments. By combining an in-depth case study with an integrative theoretical framework, this book tells a thought-provoking story of the changing influence of IWWD in a deep, comprehensive and consistent way. This book provides significant insights and lessons for both academics and practitioners.

Conventional services, such as water, energy and waste services, have been for a long time physically networked and centrally managed. Today, this delivery model appears increasingly inefficient in two respects. It often fails in guaranteeing its financial viability and equitable service access, and and it generally draws heavily on the natural resources conveyed by these services. The book aims thus at exploring how service coproduction, based on public-community collaborations, can represent a valuable alternative to the conventional service provision model. Contributions in this book look into service coproduction and its relationship with the conventional service model both in the Global North (Germany) and Global South (Bolivia, Brazil, Colombia, India, Tanzania). They also address a variety of different perspectives in coproducing conventional services, such as the role of service modernisation, the variety of non-networked solutions, the relationship with the commons, just to cite some of them. Eventually, this book provides a first comprehensive exploration of the service coproduction theory in relation to conventional services, such as water, energy and waste. The chapters originally published as a special issue in Urban Research & Practice.

Typically a large number of interests with conflicting requirements are involved in the management of a water system. The computer-based method of management introduced in this text - dynamic control - is designed to determine the most effective operational strategy.

This book provides comprehensive analysis of a number of groundwater issues, ranging from flow to pollution problems. Several scenarios are considered throughout, including flow in leaky, unconfined, and confined geological formations, crossover flow behavior from confined to confined, to semi-confined to unconfined and groundwater pollution in dual media. Several mathematical concepts are employed to include into the mathematical models' complexities of the geological formation, including classical differential operators, fractional derivatives and integral operators, fractal mapping, randomness, piecewise differential, and integral operators. It suggests several new and modified models to better predict anomalous behaviours of the flow and movement of pollution within complex geological formations. Numerous mathematical techniques are employed to ensure that all suggested models are well-suited, and different techniques including analytical methods and numerical methods are used to derive exact and numerical solutions of different groundwater models. Features: Includes modified numerical and analytical methods for solving new and modified models for groundwater flow and transport Presents new flow and transform models for groundwater transport in complex geological formations Examines fractal and crossover behaviors and their mathematical formulations Mathematical Analysis of Groundwater Flow Models serves as a valuable resource for graduate and PhD students as well as researchers working within the field of groundwater modeling.

This book addresses groundwater governance, a subject internationally recognized as crucial and topical for enhancing and safeguarding the benefits of groundwater and groundwater-dependent ecosystems to humanity, while ensuring water and food security under global change. The multiple and complex dimensions of groundwater governance are captured in 28 chapters, written by a team of leading experts from different parts of the world and with a variety of relevant professional backgrounds. The book aims to describe the state-of-the-art and latest developments regarding each of the themes addressed, paying attention to the wide variation of conditions observed around the globe. The book consists of four parts. The first part sets the stage by defining groundwater governance, exploring its emergence and evolution, framing it through a socio-ecological lens and describing groundwater policy and planning approaches. The second part discusses selected key aspects of groundwater governance. The third part zooms in on the increasingly important linkages between groundwater and other resources or sectors, and between local groundwater systems and phenomena or actions at the international or even global level. The fourth part, finally, presents a number of interesting case studies that illustrate contemporary practice in groundwater governance. In one volume, this highly accessible text not only familiarizes water professionals, decision-makers and local stakeholders with groundwater governance, but also provides them with ideas and inspiration for improving groundwater governance in their own environment.
