Understanding the impacts of urbanization on the urban water cycle and managing the associated health risks demand adequate strategies and measures. Health risks associated with urban water systems and services include the microbiological and chemical contamination of urban waters and outbreak of water-borne diseases, mainly due to poor water and sanitation in urban areas, and the discharge as well as the disposal of inadequately treated, or untreated, industrial and domestic wastewater. Climate change only exacerbates these problems, as alternative scenarios need to be taken into consideration in urban water risk management.

Urban Water Security: Managing Risks the result of a project by UNESCO 's International Hydrological Programme on the topic addresses issues associated with urban water risks. The first section of the volume describes risks associated with urban water systems and services. The volume then discusses the concept of risk management for urban water systems and explores different approaches to managing and controlling urban water risks. A concluding section presents case studies on managing urban water risks.

The Integrated Urban Water Management (IUWM) is an emerging approach to managing the entire urban water cycle in an integrated way, which is key to achieving the sustainability of urban water resources and services. The IUWM incorporates: the systematic consideration of the various dimensions of water, including surface and groundwater resources, quality and quantity issues; the implication that while water is a system it is also a component which interacts with other systems; and the interrelationships between water and social and economic development. Integrated Urban Water Management: Arid and Semi-Arid Regions - the outcome of UNESCO's International Hydrological Programme project on the topic - examines the integrated management of water resources in urban settings, focusing on issues specific to arid and semi-arid regions and on what make them different from other regions. The urban water management system is considered herein as two integrated major entities; water supply management and water excess management. The first six chapters provide an overview of the various aspects of IUWM in arid and semi-arid regions, with emphasis on water supply technologies, such as artificial recharge, water transfers, desalination, and harvesting of rainfall. Water excess management is examined in the context of both the stormwater management system and the floodplain management system. Case studies from developed and developing countries are presented in order to emphasize the various needs and challenges of water management in urban environments in arid and semi-arid regions around the world.

Salinity affects 10 to 16% of all irrigated lands while the annual rate of land loss due to waterlogging and salinity is about 0.5 million hectares per year. In this dissertation, the role of subsurface drainage to reduce these problems in irrigated agriculture in arid and semi-arid regions has been analysed and challenges for improving subsurface drainage practices have been formulated.

Although the installed subsurface drainage systems are in general technically sound and cost-effective, drainage development lags behind irrigation development and consequently a substantial part of the irrigated areas suffers from waterlogging and salinity. This is mainly because the subsurface drainage systems are designed and implemented by government, with the users, the small farmers, having little responsibility and having little input. In the adopted top-down approach the location-specific conditions and farmers? preferences are hardly taken into consideration. Furthermore, the emphasis has been on the technical aspects (the physical infrastructure), while the organizational aspects (institutional infrastructure) have been largely neglected.

To reverse the negative trend in salt build-up and waterlogging in irrigated lands in semi-arid and arid regions, a number of challenges for enhancing the role of subsurface drainage have been formulated: (i) balancing top-down against bottom-up, (ii) from standardization to flexibility and (iii) focus on capacity development.

Water is perhaps the most important chemical substance known. Without it, the very existence of life would be questionable.

Yet its detailed structure and behavior in the condensed phase and the interfaces between the condensed phase and its environment remain somewhat controversial. Indeed as ever more sophisticated and novel experimental and theoretical tools are applied to the study of bulk liquid water and ice and its interfaces, it is becoming increasingly clear that this disparate information could heat the debate on the phase and interface behavior of water rather than cool it!

This book plans to achieve a unification of views towards the goal of understanding the microscopic structure and behavior of condensed phases of water at interfaces and progressing into the bulk.

'This book bridges disciplines, previously confined to specialist journal publications, by providing a comprehensive overview of the systems analysis application to water resources. It is ideal for Masters-level courses in Water Resources Engineering where modern management techniques of optimization and modelling are highly important in the strategic management of a vital resource.' - Derek Clarke, University of Southampton, UK 'The great novelty of this book is that it presents in detail how fuzzy-set theory can be used in water resource system management. The author was one of the pioneers who opened up this new field and is considered to be one of the greatest experts in it.' - Rodolfo Soncini Sessa, Politecnico di Milano, Italy Water resources management is increasingly interdisciplinary and must take into account complex socioeconomic factors and environmental variables. This book describes the 'systems approach' and its application to contemporary water resources management, focusing on three main sets of tools: simulation, optimization and multi-objective analysis. This approach is presented within the context of sustainable planning and development under conditions of uncertainty. Managing Water Resources: Methods and Tools for a Systems Approach introduces system dynamic simulation as a tool for integrated modelling and contains coverage of the use of fuzzy sets for incorporating objective and subjective uncertainties. The book combines theory with many practical examples, as well as including programs and exercises on downloadable resources. It comprises both an advanced text for students of water resources and civil or environmental engineering and a practical guide for professionals. Published jointly with UNESCO and International Hydrological Programme

Published in 1991, the first edition of "The Practical Handbook of Ground-Water Monitoring" quickly became the gold standard reference on the topic of ground-water monitoring. But, as in all rapidly evolving fields, regulations change, technology advances, methods improve, and research reveals flaws in prior thinking. As a consequence, books that document the state of the science, even widely acknowledged definitive works, become outdated and need to be rewritten periodically to stay current. Reflecting this and renamed to highlight its wider scope, The Practical Handbook of Environmental Site Characterization and Ground-Water Monitoring, Second Edition provides an updated look at the field. Completely revised, the book contains so much new information that it has doubled in size.

Containing the most up-to-date information available, this second edition emphasizes the practical application of current technology. It covers environmental site characterization and ground-water monitoring in great detail, from the federal regulations that govern environmental investigations, to the various direct and indirect methods of investigating and monitoring the subsurface, to the analysis and interpretation of complex sets of environmental data.

Cheaper, better, faster was the mantra of the 1990s, resulting in more streamlined approaches to both environmental site characterization and ground-water monitoring, but also pitting the application of good science against the mandate to get a project done as quickly and inexpensively as possible. This book provides unbiased, technical discussions of the tremendously powerful tools developed in the last decade, helping environmental professionalsstrike a balance between good science and economics.

This book offers essential information on geospatial technologies for water resource management and highlights the latest GIS and geostatistics techniques as they relate to groundwater. Groundwater is inarguably India's single most important natural resource. It is the foundation of millions of Indian farmers' livelihood security and the primary source of drinking water for a vast majority of Indians in rural and urban areas. The prospects of continued high rates of growth in the Indian economy will, to a great extent, depend on how judiciously we can manage groundwater in the years to come. Over the past three decades, India has emerged as by far the single largest consumer of groundwater in the world. Though groundwater has made the country self-sufficient in terms of food, we face a crisis of dwindling water tables and declining water quality. Deep drilling by tube wells, which was once part of the solution to water shortages, is now in danger of becoming part of the problem. Consequently, we urgently need to focus our efforts on the sustainable and equitable management of groundwater. Addressing that need, this book presents novel advances in and applications of RS-GIS and geostatistical techniques to the research community in a precise and straightforward manner.

One of the main problems confronting the world of the 21st Century is a shortage of water. There is already severe scarcity in many regions of the world, causing tremendous problems for local populations and indeed entire societies. There is insufficient water available for the production of food to alleviate poverty and starvation; the lack of water hampers industrial, urban and tourism development, forcing restrictions on other sectors, especially agriculture; health problems arise as the deterioration of ground and surface waters favours water-borne diseases, which flourish in the absence of decent water distribution and sewerage systems. Water conflicts still arise in areas under stress, while water for nature has become a vanishing priority in such zones.

This book is a guide to the establishment of regional and/or local guidelines for developing and implementing new ideas for coping with water scarcity. The basic premise underlying the book is that water scarcity will persist, so personal, human and society-wide skills will be needed to cope with it while living in harmony with the necessary environmental constraints. The book provides basic information to assist decision makers, water managers, engineers, agronomists, social scientists and other professions (and their students) in formulating coherent, hopefully harmonious and consolidated views on the issue. Guidelines are also given for introducing the general public to the concept of water scarcity and how to deal with it.

Professionals involved in the planning, design, operation, and construction of water, wastewater, and stormwater systems need to understand the productivity-enhancing applications of GIS. Inspired by an ASCE-sponsored continuing education course taught by the author, GIS Applications for Water, Wastewater, and Stormwater Systems focuses on the practical aspects of software and data tools that enable GIS applications. The book documents and analyzes effective use of GIS, demonstrating how you can apply the technology to make tasks easier to perform, saving time and money for your organization.

The book first describes GIS, detailing its importance and explaining how to avoid potential pitfalls via a needs analysis study. It then describes GIS-related technologies that are crucial in applications development: remote sensing; DEM data; GPS; Internet applications; and mobile GIS. The final ten chapters focus on the "Four Ms" of the water industry-Mapping, Monitoring, Modeling, and Maintenance-applications that define the most important activities for efficient management of water, wastewater, and stormwater systems.

Promoting a performance- (or outcome-) based style of learning, each chapter first states learning objectives and later concludes with a chapter summary and questions. The text encourages more effective and natural inductive study by first presenting case studies, then explaining procedures. This volume supplements the text with numerous maps, tables, and illustrations.

This book provides a comprehensive overview of the current knowledge on the fate and interaction of pharmaceuticals in soil-crop systems. It addresses the principles of their transport, uptake and metabolism and reviews methodologies for their analytical determination. It also discusses ecotoxicological effects arising from their presence and highlights bioremediation approaches for their removal. The use of treated wastewater to irrigate crops is becoming more widespread in regions where freshwater is limited. This practice conserves freshwater resources and contributes to nutrient recycling. However, concerns remain regarding the safety of irrigation with treated wastewater since it contains residues of pharmaceuticals that have survived treatment, which means that soil and fauna are potentially exposed to these xenobiotics. Various pathways govern the fate of pharmaceuticals in crop-soil systems, including soil degradation; formation of non-extractable residues; uptake by soil-dwelling organisms (e.g. earthworms); and uptake, transport, and metabolism in agricultural crops. Investigations into these aspects have only recently been initiated, and there is still a long way to go before a meaningful assessment of the impact of wastewater has been completed.
