Field Practices for Wastewater Use in Agriculture discusses the growing importance of wastewater application in the field of agriculture. Addressing the tremendous need for the irrigation sector to reduce the demand for freshwater in agriculture, this volume looks at wastewater as a source for agricultural irrigation. The volume is divided into four sections: current and emerging issues in wastewater use in agriculture, wastewater management with biological systems, effective field practices for wastewater use, and case studies that provide information on scientific analytical studies on the environment under the influence of wastewater quality from different pollution sources. This book sheds light on the vast potential of wastewater use in agricultural irrigation while also considering safety of the agricultural products for human consumption. Much emphasis has also been given to technological aspects for the treatment of wastewater to protect our environment for better public health protection.

Anthropogenic climate change may lead to intensification of the global hydrological cysle and to increased flooding risk of rivers across Europe. A series of extreme floods in European rivers in the last decades have stimulated discussions about the possible effects of climate variability/change and human interventions in river basins. A synoptic-climatological analysis was carried out to elucidate the observed precipitation change in the Meuse basin, in northwestern Europe. The findings of this research will be valuable to those developing improved flood protection strategies, as well as those engaged in water resource management in river basins similar to the Meuse.

This book will present the theory involved in wastewater treatment processes, define the important design parameters involved, and provide typical values of these parameters for ready reference; and also provide numerical applications and step-by-step calculation procedures in solved examples. These examples and solutions will help enhance the readers' comprehension and deeper understanding of the basic concepts, and can be applied by plant designers to design various components of the treatment facilities. It will also examine the actual calculation steps in numerical examples, focusing on practical application of theory and principles into process and water treatment facility design.

Marine Spatial Planning (MSP) is an integrated and comprehensive approach to ocean governance and is used to establish a rational use of marine space and reconcile conflicting interests of its users. MSP allows both a high level of environmental protection and a wide range of human activities and emphasizes coordinated networks of national, regional and global institutions. This book focuses on the framework of international law behind MSP and especially on the transboundary aspects of MSP. It first sets out a general framework for transboundary MSP and then moves on to compare and assess differences and similarities between different regions. Specific detailed case studies include the EU with the focus on the Baltic Sea and North Sea, the Bay of Bengal and Great Barrier Reef in Australia. The authors examine the national and regional significance of MSP from an integrated and sustainable ocean governance point of view. They also show how transboundary MSP can create opportunities and positive initiatives for cross-border cooperation and contribute to the effective protection of the regional marine environment.

The Nile River and its basin extend over a distinctive geophysical cord connecting eleven sovereign states from Egypt to Tanzania, which are home to an estimated population of 422.2 million people. The Nile is an essential source of water for domestic, industrial and agricultural uses throughout the basin, yet for more than a century it has been at the centre of continuous and conflicting claims and counter-claims to rights of utilization of the resource. In this book the author examines the multifaceted legal regulation of the Nile. He re-constructs the legal and historical origin and functioning of the British Nile policies in Ethiopia by examining the composition of the Anglo-Ethiopian Treaty of 1902, and analyses its ramifications on contemporary riparian discourse involving Ethiopia and Sudan. The book also reflects on two fairly established legal idioms - the natural and historical rights expressions - which constitute central pillars of the claims of downstream rights in the Nile basin; the origin, essence and legal authority of the notions has been assessed on the basis of the normative dictates of contemporary international watercourses law. Likewise, the book examines the non-treaty based claims of rights of the basin states to the Nile waters, setting out what the equitable uses principle entails as a means of reconciling competing riparian interests, and most importantly, how its functioning affects contemporary legal settings. The author then presents the concentrated diplomatic movements of the basin states in negotiations on the Transitional Institutional Mechanism of the Nile Basin Initiative (NBI) - pursued since the 1990's, and explains why the substance of water use rights still continued to be perceived diversely among basin states. Finally, the specific legal impediments that held back progress in negotiations on the Nile Basin Cooperative Framework are presented in context.

Pollution of water sources with emerging contaminants (micropollutants) is a fact known worldwide. Although the risks of micropollutants in sources of water are partly recognized, interpretation of consequences are controversial; thus, the future effects of altered water with micropollutants remains uncertain and may constitute a point of concern for human beings when potable water consumption is involved. Therefore, many drinking water utilities target as an important goal high-quality drinking water production to lessen quality considerations that may arise from the consumers. In this thesis, by means of the use of multivariate data analysis techniques, removal quantification is effectively determined and more understanding of the separation of micropollutants by membranes is achieved.

This new book covers drinking water regulations such as disinfectant by-products, synthetic organics, inorganic chemicals, microbiological contaminants, volatile organic chemicals, radionuclides, fluoride, toxicological approaches to setting new national drinking water regulations, and trihalomethanes. In addition, organic and inorganic compounds scheduled to be regulated in 1989 and new candidates for the 1990s regulations are detailed.

Our objective in this book and in subsequent volumes of the Uniscience Series on Water Pollution Control Technology, is to provide a reference manual for design engineers, planners, and managers in industry and government. This is particularly important in the present critical period for implementation of water pollution controls.

This book explores a new realm in data-based modeling with applications to hydrology. Pursuing a case study approach, it presents a rigorous evaluation of state-of-the-art input selection methods on the basis of detailed and comprehensive experimentation and comparative studies that employ emerging hybrid techniques for modeling and analysis. Advanced computing offers a range of new options for hydrologic modeling with the help of mathematical and data-based approaches like wavelets, neural networks, fuzzy logic, and support vector machines. Recently machine learning/artificial intelligence techniques have come to be used for time series modeling. However, though initial studies have shown this approach to be effective, there are still concerns about their accuracy and ability to make predictions on a selected input space.

Existing views on geodynamics (recharge, migration, discharge) of uids at deep layers of petroliferous basins are summarized. The in ltration and elision th- ries explaining development of uid pressures in deep formations are called into question based on quantitative estimates available for some artesian (petroliferous) basins. Using the West Siberian, Pechora, Terek-Kuma, Bukhara-Karshi, and other petroliferous basins as examples, the stratum-block structure of deep formations is substantiated for strati ed systems of platform in inter- and intramontane depr- sions. It is shown that petroliferous reservoirs at great depths are characterized, regardless of lithology, by largely ssure-related capacity and permeability (clayey rocks included) changeable in space and through geological time. Much attention is paid to development of abnormally high formation pressures. Peculiarities in heat and mass transfer at deep levels are considered for different regions. The energetic formation model substantiated for deep uids explains different anomalies (baric, thermal, hydrogeochemical, mineralogical, and others) at deep levels of platforms. Based on hydrogeodynamic considerations, the theory of oil origin and formation of hydrocarbon elds is proposed. The book is of interest for oilmen, hydrogeo- gists, geologists, and specialists dealing with prospecting of petroliferous deposits as well as industrial, mineral, and thermal waters in deep formations of strati ed sedimentary basins. vii Contents 1 Existing Views on Fluidodynamics in Petroliferous Formations . . 1 References . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 11 2 Investigation Methods of Deep Fluidodynamics . . . . . . . . . . . 15 2. 1 Methods of Formation Pressure Reducing . . . . . . . . . . . . 16 2. 2 Assessment of Directions of Density-Variable Fluid Flows by the "Filtration Force" Method . . . . . . . . . . . . .

The natural scarcity of water in arid and semiarid regions, aggravated by man-made factors, makes it difficult to achieve a reliable water resources supply. Communities in these areas pay the price for thousands of years of water manipulation. Presenting important insight into the complexities of arid region hydrology, Engineering Hydrology of Arid and Semi-Arid Regions explores the key components for formulating and implementing integrated management approaches in catchment (wadi) systems. The book introduces the engineering hydrology of arid and semi-arid regions, covering meteorological processes and hydrology. The author discusses precipitation and precipitation losses, catchment characteristics, and runoff estimation methods. He also examines streamflow measurements and hydrographs, flood routing, and groundwater hydrology, including the basic equations of groundwater flow and analytic solutions describing flow aquifers, pumping tests, and salt water intrusion. Building on this foundation, the book then delineates sediment yield in watersheds and streams and the design of hydraulic structures for protection and management of water resources systems. It includes case studies, conversion tables, and modeling software. During the last two decades, research efforts and networking have enhanced the state of knowledge about arid and semi-arid areas, especially watershed and catchment systems. Pulling this information together into a comprehensive resource, this book provides a better understanding of wadi hydrology, capacity-building processes, water education and training, and institutional development. This understanding can then be used to select the appropriate tools to support water management and optimize the sustainable use of water resources.

Used in the production of a wide number of fine chemicals and pharmaceuticals, the Friedel-Crafts acylation reaction represents a synthetic process of great interest to organic chemists of academia and industry. Nearly 40 years since the last major treatise on the topic and reflecting the growing emphasis on green technology, Advances in Friedel-Crafts Acylation Reactions: Catalytic and Green Processes focuses on how to make this reaction more economically and environmentally friendly by using green acylating conditions, thus minimizing the formation of waste and decreasing production costs. Divided into four parts, the book explores stoichiometric acylations, catalytic homogeneous acylations, catalytic heterogeneous acylations, and phenol acylations. It is structured according to the role played by the catalyst in the activation of reagents as well as in the different modes of regioselectivity encountered in the acylation of arenes, aromatic ethers, and phenols. Incorporating examples of all acid-catalyzed Friedel-Crafts acylation reactions, the text considers classic Lewis and Broensted acid types along with more innovative and advanced multicomponent superacid catalysts. These range from rare earth triflates or triflimides and their combination with ionic liquids to metal-promoted zeolites and zeotypes, clays, polymetal oxides, sulfated zirconia, heteropoly acids, and Nafion. The book emphasizes the major industrial applications, providing a critical assessment of the differences, advantages, and disadvantages of homogeneous and heterogeneous catalysis. Helping readers to better understand the mechanism of the Friedel-Crafts acylation, the examples in the book substantiate the development of more effective catalysts and more selective processes achieved during the last few decades, enabling industry to embark on a safer and more efficient synthesis of aromatic ketones for the manufacture of a wide array of products.

Bio-optical Modeling and Remote Sensing of Inland Waters presents the latest developments, state-of-the-art, and future perspectives of bio-optical modeling for each optically active component of inland waters, providing a broad range of applications of water quality monitoring using remote sensing. Rather than discussing optical radiometry theories, the authors explore the applications of these theories to inland aquatic environments. The book not only covers applications, but also discusses new possibilities, making the bio-optical theories operational, a concept that is of great interest to both government and private sector organizations. In addition, it addresses not only the physical theory that makes bio-optical modeling possible, but also the implementation and applications of bio-optical modeling in inland waters. Early chapters introduce the concepts of bio-optical modeling and the classification of bio-optical models and satellite capabilities both in existence and in development. Later chapters target specific optically active components (OACs) for inland waters and present the current status and future direction of bio-optical modeling for the OACs. Concluding sections provide an overview of a governance strategy for global monitoring of inland waters based on earth observation and bio-optical modeling.

Initially associated with hi-tech irrigated agriculture, drip irrigation is now being used by a much wider range of farmers in emerging and developing countries. This book documents the enthusiasm, spread and use of drip irrigation systems by smallholders but also some disappointments and disillusion faced in the global South. It explores and explains under which conditions it works, for whom and with what effects. The book deals with drip irrigation 'behind the scenes', showcasing what largely remain 'untold stories'. Most research on drip irrigation use plot-level studies to demonstrate the technology's ability to save water or improve efficiencies and use a narrow and rather prescriptive engineering or economic language. They tend to be grounded in a firm belief in the technology and focus on the identification of ways to improve or better realize its potential. The technology also figures prominently in poverty alleviation or agricultural modernization narratives, figuring as a tool to help smallholders become more innovative, entrepreneurial and business minded. Instead of focusing on its potential, this book looks at drip irrigation-in-use, making sense of what it does from the perspectives of the farmers who use it, and of the development workers and agencies, policymakers, private companies, local craftsmen, engineers, extension agents or researchers who engage with it for a diversity of reasons and to realize a multiplicity of objectives. While anchored in a sound engineering understanding of the design and operating principles of the technology, the book extends the analysis beyond engineering and hydraulics to understand drip irrigation as a sociotechnical phenomenon that not only changes the way water is supplied to crops but also transforms agricultural farming systems and even how society is organized. The book provides field evidence from a diversity of interdisciplinary case studies in sub-Saharan Africa, the Mediterranean, Latin America, and South Asia, thus revealing some of the untold stories of drip irrigation.

This book examines the political economy that governs the management of international transboundary river basins in the developing world. These shared rivers are the setting for irrigation, hydropower and flood management projects as well as water transfer schemes. Often, these projects attempt to engineer the river basin with deep political, socio-economic and environmental implications. The politics of transboundary river basin management sheds light on the challenges concerning sustainable development, water allocation and utilization between sovereign states. Advancing conceptual thinking beyond simplistic analyses of river basins in conflict or cooperation, the author proposes a new analytical framework. The Transboundary Waters Interaction NexuS (TWINS) examines the coexistence of conflict and cooperation in riparian interaction. This framework highlights the importance of power relations between basin states that determine negotiation processes and institutions of water resources management. The analysis illustrates the way river basin management is framed by powerful elite decision-makers, combined with geopolitical factors and geographical imaginations. In addition, the book explains how national development strategies and water resources demands have a significant role in shaping the intensities of conflict and cooperation at the international level. The book draws on detailed case studies from the Ganges River basin in South Asia, the Orange-Senqu River basin in Southern Africa and the Mekong River basin in Southeast Asia, providing key insights on equity and power asymmetry applicable to other basins in the developing world.
