The objective of this book is to summarize and critically assess the current status, development trends and needs of three basic defensive elements that safeguard the quality and environmental safety of soil and water/sediments: early warning monitoring, protection and remediation measures, with particular regard to the viability of methods and technologies, i.e. easiness-to-use, reliability, cost-effectiveness, high efficiency and non-destructive character of remediation that is of particular importance considering the scale of application. The primary aim of the book is to contribute to the improving maintenance of ecosystems, and specifically to summarize and add to information on how best to protect our soils and aquifers, prevent migration and mobilization of pollutants and how to enhance their degradation and/or immobilization. Mechanism of action is considered the first priority, but optimization of technical construction/application details are of no lesser importance. In the permeable reactive barriers, and other preventive/remediation measures, a number of novel integrated physicochemical and biochemical methods are presented. The remediation solutions for soil pollution are focused on non-destructive methods such as phyto- and ecoremediation that would preserve soil properties during and after decontamination. The contributors to the book are internationally recognized experts, which present both state-of-the art and novel approaches in the above fields that makes the book unique with respect to the scope.

This book highlights the relationship between the water sector and various other sectors in order to establish an improved understanding of the importance of water resources as an essential cross-cutting vector of socio-economic development. The book is both policy and practice oriented and is not constrained by existing definitions on water security. It includes actual experiences of policy, management, development and governance decisions taken within the water sector, and examples on how these have affected the energy and agricultural sectors as well as impacted the environment, and vice versa, as appropriate. It also discusses trade-offs, short and long-term implications, lessons learnt, and the way forward. The book includes case studies on cities, countries and regions such as Australia, China, Singapore, Central Asia, Morocco, Southern Africa, France, Latin America, Brazil and California.

The book is the first pioneering study to assess the impacts of the megaconferences on water policies, programmes and projects at global, regional and national levels. The results are bleak. The evaluation indicated that except for the UN Water Conference, held in Argentina in 1977, the impacts of the subsequent megaconferences have been at best marginal in terms of knowledge generation and synthesis, poverty alleviation, and/or environmental conservation.

In the 20th century, water management focused on the local scale of interest. In the 21st century we will be facing changes in quantity and quality of our water cycle. Triggering forces behind these new challenges are industrialisation, population growth and the delayed awareness that we are to expect a global change. The magnitude and distribution of global changes are not exactly predictable, because we live in an always changing environment, are faced with severe and interfering processes, which all are not yet sufficiently understood. Therefore, to shoulder this task, hydrology should embrace more integrative and interdisciplinary approaches than already existing and has to achieve more flexibility in assessments and decisions. To better approach this challenge, catchments related solutions are more important than local solutions, to satisfy the water demand of agriculture, ecosystems, industry and the private sector. And we should keep in mind that the environment has a "sustainable memory" and our knowledge about attenuation capacities and resilience of the environment is still low.

There are approximately 50,000 small water supplies in the UK alone, and thousands more worldwide. Dealing with the idiosyncratic characteristics of small water supplies requires specialist knowledge, and this book provides invaluable guidance for professionals.

Based on the extensive practical experience of the author, this book covers how small independent supplies differ from public water supplies, and outlines the health dangers they pose, along with detailed instruction in water sampling and risk assessment techniques. Clapham describes the different types of water supplies including their construction and treatment systems, and discusses common problems encountered. A wide range of case studies bring the theory to life, and both UK and European legislation is discussed. There is also a sizeable section dealing with small water supplies in developing countries.

In the countries of the Middle East and Northern Africa, reclaimed wastewater is recognized as a non-conventional water resource. However, substandial amounts are still discharged into water courses without further treatment. The objective of this research was to analyse the technological, regulatory, institutional, financial and socio-cultural opportunities, seen as incentives; and the constraints, perceived as disincentives, which influence the adoption of wastewater treatment and reuse. Fieldwork was carried out in Jordan and Tunisia, countries which have made great strides in raising the proportion of re-used wastewater. Unexpectedly, farmers and customers proved well-prepared to use reclaimed water in irrigation, and to buy crops raised in the irrigated fields. Abu-Madi stresses the need for raising the price of freshwater, reflecting its true scarcity, thus creating a stronger incentive to utilise reclaimed wastewater.

This book presents the proceedings of the NATO Advanced Research Workshop Wastewater Reuse - Risk Assessment, Decision-Making and Environmental Security, held in Istanbul in October, 2006. The papers survey the current state of water management in the world and especially the Middle East and Mediterranean regions, and address some of the most difficult international conflicts. Wastewater, a by-product of agricultural, industrial or domestic water use, can be an environmental hazard causing damage to soil and to water resources. However, as demonstrated in many of the papers, it can also be a benefit if exploited correctly. Papers presented cover in great detail and depth the risk assessment, decision-making approaches and environmental security. Information about design, installation, management of wastewater treatment facilities, and use for saline water is provided by experts from the EU, UNESCO, World Bank, United States, Canada and other contributing agencies.

This book treats the problem of transient hydraulic computation, for hydroelectric plants and pumping stations, with an emphasis on numerical methods. The topics covered include: the waterhammer in hydraulic systems under pressure; experimental results concerning the waterhammer; protection of pumping stations with reference to the waterhammer; hydraulic resonance in hydroelectric power plant and pumping stations; mass oscillation in hydraulic surge systems; hydraulic stability of systems endowed with surge tanks; experimental results in the study of mass oscillations; hydroelectric power plants and pumping stations designed in complex hydraulic schemes; and computation of unsteady motions in the intermediate domain between rapid and slow motions. This book is not a standard monograph based on previously published material, but is primarily grounded on the theoretical and applied results obtained by authors during more than 20 years of practice. It considers the problems of hydraulic computation as encountered in the design of a significant number of hydroelectric power plants and pumping stations in Romania.

The books currently available on this subject contain some elements of physical-chemical treatment of water and wastewater but fall short of giving comprehensive and authoritative coverage. They contain some equations that are not substantiated, offering empirical data based on assumptions that are therefore difficult to comprehend. This text brings together the information previously scattered in several books and adds the knowledge from the author's lectures on wastewater engineering.

Physical-Chemical Treatment of Water and Wastewater is not only descriptive but is also analytical in nature. The work covers the physical unit operations and unit processes utilized in the treatment of water and wastewater. Its organization is designed to match the major processes and its approach is mathematical. The authors stress the description and derivation of processes and process parameters in mathematical terms, which can then be generalized into diverse empirical situations. Each chapter includes design equations, definitions of symbols, a glossary of terms, and worked examples.

One author is an environmental engineer and a professor for over 12 years and the other has been in the practice of environmental engineering for more than 20 years. They offer a sound analytical mathematical foundation and description of processes. Physical-Chemical Treatment of Water and Wastewater fills a niche as the only dedicated textbook in the area of physical and chemical methods, providing an analytical approach applicable to a range of empirical situations

A stand-alone working document, Stormwater Effects Handbook: A Toolbox for Watershed Managers, Scientists, and Engineers assists scientists and regulators in determining when stormwater runoff causes adverse effects in receiving waters. This complicated task requires an integrated assessment approach that focuses on sampling before, during, and after storms. The Handbook supplies assessment strategies, sample testing and collection methods, and includes illustrative figures and tables.

The authors introduce an innovative design that can be tailored to address a wide range of environmental concerns, such as: ecological and human health risk assessments, water quality or biological criteria exceedences, use impairment, source identification, trend analysis, determination of best management practices, stormwater quality monitoring for NPDES Phase I and II permits and applications, and total maximum daily load assessments. They provide case studies to illustrate the effectiveness of this approach and the data that can be compiled.

Containing reviews of emerging technologies that hold promise for more effective receiving water evaluations, this book gives you detailed information on selecting methods and carrying out comprehensive evaluations. It includes guidance for the experimental design measurements, as well as standard and advanced statistical methods for data evaluations. Despite the complexity of stormwater management, successful and accurate assessments of their impact are possible by following the integrated approaches described in Stormwater Effects Handbook: A Toolbox for Watershed Managers, Scientists, and Engineers.

The Ural river, the third longest river in Europe, is a unique ecosystem. Unlike other large European rivers the river has not been regulated and the natural hydrological regime is still intact. Thanks to that it has the only remaining spawning habitats in the entire Caspian basin for all sturgeon species. Nevertheless, this fact is not well known to the broader scientific and environmental communities.

The Ural river is also an interesting place due to its rich history of sustainable use of aquatic resources in general and sturgeons in particular. The traditional life style of the local communities, Ural Cossacks, was focused on the preservation and rational use of sturgeon species. This interesting experience of sustainable river-related management is not adequately reported in literature.

To secure further Ural sturgeon preservation the river basin ecosystem and human activities in the region must be managed in an integrated sustainable manner. The sturgeon species can be used as a natural indicator and an incentive for such transboundary IWRM cooperation taking into account all three components of sustainable development: economic, social and environmental. To secure basin IWRM and sturgeon stock restoration the International Ural Sturgeon Park should be established. The role of the Park will be to secure the natural reproduction in the Ural as the primary strategy for the sturgeon stock replenishment. The Ural River Basin Project, which aims at the creation of such a Park, was launched in 2007. This volume is devoted to the uniqueness, history and problems of the Ural river basin, its sturgeons and perspectives of their conservation.

Emerging Membrane Technology for Sustainable Water Treatment provides the latest information on the impending crisis posed by water stress and poor sanitation, a timely issue that is one of the greatest human challenges of the 21st century.

This broad review of the development of US water resource policy analysis and practice offers perspectives from several disciplines: law, economics, engineering, ecology and political science. While the historical context provided goes back to the early 19th century, the book concentrates on the past 60 years and features a discussion of the difficulty that has generally been encountered in bringing the disciplines of economics and ecology into collaboration in the water resource context.The book explores the evolution of water related analytical capabilities and institutions and provides illustrations from case studies, concluding with recommendations for research, institutional change and action. Though designed to be a background textbook for interdisciplinary graduate seminars in water resources planning and management, it is accessible to interested lay readers and those who have policymaking or implementation responsibility but lack a technical background. The book will appeal to students and faculty in water policy, economics, and engineering, and in interdisciplinary programs organized around water resource problems and questions. Policy makers and general readers will also appreciate this non-technical introduction.

Carbonate aquifers are an important source of water throughout the world. They are complicated systems and not always easy to interpret. Caves and channels form in the rock, leading to complex flow pathways and unpredictable contaminant behaviour. This volume covers the range of techniques used to analyse groundwater flow and contaminant transport in carbonate aquifers. The book opens with a review of thoughts and methods, and continues by discussing the use of tracers, hydrograph and hydrochemograph evaluation, estimation of aquifer properties from outcrop studies, numerical simulation, analogue simulation, and 3-D visualization of conduits. Other papers address the critical evaluation of matrix, fracture and conduit components of flow and storage. An understanding of these approaches is important to engineers or hydrogeologists working in carbonate aquifers.

This volume presents a critical analysis and timely synthesis of the past decade of intensive research, development, and demonstrations on the in situ bioremediation of perchlorate in groundwater. The intended audiences include the decision makers, practicing engineers and hydrogeologists who will select, design, and operate these remedial systems, as well as researchers seeking to improve the current state-of-the-art. Our hope is that this volume will serve as a useful resource to assist remediation professionals in applying and developing the technology as effectively as possible. An overview of the current state-of-understanding of perchlorate remediation is followed by a discussion of basic principles of microbial and abiotic processes, and of the engineering and implementation issues underlying the technologies described. Characterization of both anthropogenic and natural sources of perchlorate, including isotopic analysis to distinguish between differing sources, precedes discussions of the advantages, performance, and relative costs of applying a range of remedial technologies. Active, semi-passive, and passive in situ bioremediation are fully described and compared with emphasis on field application. Cost information for each technology, using case studies and analyses of several template sites, covers capital costs, as well as costs for laboratory testing, pilot-scale demonstration, design, system operation, monitoring and maintenance during operations, and demolition and restoration after remediation. In addition, analogous cost data are presented for pump-and-treat systems for each template site to illustrate the potential cost savings associated with the use of alternative approaches. Emerging technologies such as monitored natural attenuation, phytoremediation, and vadose zone bioremediation are described, and field demonstrations are used to illustrate the current stage of maturity and the potential applicability of these approaches for specific situations. Each chapter in this volume has been thoroughly reviewed for technical content by one or more experts in each subject area covered.
