This book argues that groundwater pollution risk assessment is the essential foundation of groundwater pollution prevention and control. It is on this basis that economic leverage is used to make new breakthroughs in groundwater protection and governance. Presenting a case study on the Jilin Section of the Songhua River, the book applies the overlay index method to assess the shallow groundwater pollution risk and identify high-risk areas and major pollution sources in an effort to identify the mechanism of interaction between industrial structures and groundwater pollution. Further, it proposes concrete measures for preventing and controlling groundwater pollution from an industrial economics perspective. As such, the book offers a valuable resource for all graduate students, lecturers and researchers who are interested in learning about resources and environmental economics.

This proceedings book provides the latest developments on water as a unique resource that can meet the fundamental needs of human beings and ecosystems. Wastewater generated in industrial, commercial, residential and sensible places must take care as it may pollute the ground and surface water if not treated properly. Environmental pollution discharged from industrial, commercial, residential and sensible places must take care as it may pollute the air, water and land if not treated properly. Most of the design and development of wastewater technologies and environmental treatment were unable to take load as there is huge amount of wastewater and environmental pollution that was generating every day. This threatens the sustainable development, and it needs to solve in accurate, reliable, urgent and timely. Our interest is sustainable innovative and technological transfer approaches which can be used available for supporting, operationalizing and delivering sustainable wastewater technologies and environmental treatment. The authors hope that the book covers possible spectrum of wastewater technologies and environmental treatment to high level of environmental protection, clean and green management lessons, identifies the barriers for transformative change and then informs agenda and initiatives for the sustainable development. ICWTET2020 is dedicated to wastewater technologies and environmental treatment, with a focus on the high level of environmental protection. The aim of the ICWTET2020 is to disseminate current knowledge and sustainable development, share experience and lessons learned and stimulate discussion and reflection, thus promoting a sustainable paradigm shift. The final purpose is to contribute transformative change towards sustainable development through dissemination of sustainable wastewater technologies and environmental treatment.

This book examines the role of The International Maritime Organization (IMO) in the prevention and control of pollution of the marine environment from vessels with a particular reference to the current north-south tensions regarding the strategy for combating climate change in the maritime sector as well as the prevention of marine pollution from the ship-breaking industry. The IMO, a United Nations specialized agency, has been entrusted with the duty to provide machinery for cooperation among governments for the prevention and control of pollution of the marine environment from vessels. The organization is responsible for drafting legal instruments as well as for facilitating technical cooperation for the protection of the marine environment. Although IMO legal instruments are mainly targeted at the prevention of pollution of the marine environment from vessels, there is a trend towards a liberal interpretation of this, and the organization has expanded its work to areas like shipbreaking, which is essentially a land-based industry.

This book highlights the application of Geographical Information System (GIS) and nature based algorithms to solve the problems of water and water based renewable energy resources. The irregularity in availability of resources and inefficiency in utilization of the available resources has reduced the potentiality of water and water based renewable energy resources. In recent years various soft computation methods (SCM) along with GIS were adopted to solve critical problems. The book collects various studies where many SCMs were used along with GIS to provide a solution for optimal utilization of natural resources for satisfying the basic needs of the population as well as fulfilling their burgeoning energy demands. The articles depict innovative application of soft computation techniques to identify the root cause and to mitigate the uncertainty for optimal utilization of the available water resources. The advantage of SCM and GIS were used to maximize the utilization of water resources under cost and time constraints in face of climatic abnormalities and effect of rapid urbanization.

The NATO Advanced Research Workshop, "Decision Support for Natural Disasters and Intentional Threats to Water Security" was the result of close collaboration between environmental, security, water resource, and health officials in the United States and Croatia. The premise of the Workshop is that multiple, disparate threats to water security exist, and that shared decision support structures provide effective means for avoiding and responding to potential or actual situations. The Workshop was co-directed by Professors Tissa Illangasekare of the Colorado School of Mines, and Dragutin Geres of Hrvatske vode. The Workshop was organized into a series of case studies, presentation of management tools, or a combination of the two. Presentations were further organized as to (1) Natural Occurrences, (2) Anthropogenic Causes, and (3) Decision Support Tools. Delegates from eleven countries assembled to explore these topics at the Hotel Dubrovnik President in Dubrovnik from April 22-25, 2007. A total of thirty delegates from NATO, Partner, Mediterranean Dialog, or other countries were in attendance. The final program included technical sessions using a presentation and dialog format, a field trip, and networking sessions. There were twenty five technical presentations supported by seventeen formal papers (many updated in late-2008 and 2009), and these form the basis for these proceedings. xi ACKNOWLEDGEMENTS The co-directors and organizers of this Advanced Research Workshop a- nowledge the NATO Science Programme for major financial support and for providing detailed guidance on how best to organize and execute a meeting of this nature.

When Europeans first arrived at what is now California's San Joaquin Valley, they found a vast landscape of wetlands, small ponds, riparian forests, and grasslands surrounding three large swampland lakes. What greets a visitor to the region today is a dramatically different view of mile after mile of row crops, vineyards, orchards, and grazing acreage - some of the most fertile and productive agricultural land in the world. This remarkable transformation, with its enduring consequences, is at the center of Ruling the Waters, a legal, social, and environmental history of how western water law shaped, and was shaped by, the subjugation of the largest freshwater wetlands wildlife habitat in the West. At the heart of efforts to wrest arable land from the region was the Kern River, which rises in the Sierra Nevada and carries snowmelt to what was once a great network of lakes, sloughs, and marshes at the southern end of California's Central Valley. In Ruling the Waters Douglas R. Littlefield describes how, over the course of the nineteenth and early twentieth centuries, pioneers and entrepreneurs diverted water out of this network of waterways to extract gold in the mountains and irrigate farms lower down the river, and how the law was made to accommodate these practices. Struggles over the Kern River's water established one of the most important concepts in water law in some parts of the United States - that prior appropriation, dependent on the chronological order of diversions from waterways, could legally coexist with riparian rights, which restrict water usage to landownership directly next to a river or stream. Littlefield traces this concept to the 1886 California Supreme Court case of Lux v. Haggin - which pitted the giant farming and cattle company of Miller & Lux against a prominent land baron, James B. Haggin - and shows how the lawsuit profoundly shaped future waters issues, which in turn influenced water laws in other western states that were grappling with similar questions. Far from a dry legal history, Ruling the Waters tells a story with world-wide historical environmental ramifications, a tale of competing personalities and values and visions that forever changed both the economy and the ecology of the American West.

This book deals with water management, one of the most challenging issues of contemporary society. Research and innovation in the field of water management must address certain fundamental aspects: access to water, water quality, water treatment, transboundary effect of water, etc. A comprehensive analysis was performed in a national research program of Moldova, entitled "Research and management of water quality". The main goal of the research program was to create and improve the legal, scientific and methodological, technological basis and sustainable development of water, implementation of modern technologies in water supply, treatment and reuse. Other priorities include expansion of access to water sources, improvement of environmental protection, especially water protection against pollution and depletion, efficient water use and establishing an effective monitoring system for disaster prevention. The topics concern research of water structure and quality, surface water, groundwater, water treatment, irrigation technologies and water pollution by remains from industry, one of the main environmental problems of our time. The book helps to get to coherent water policies of states.

This open access textbook provides a concise introduction to economic approaches and mathematical methods for the study of water allocation and distribution problems. Written in an accessible and straightforward style, it discusses and analyzes central issues in integrated water resource management, water tariffs, water markets, and transboundary water management. By illustrating the interplay between the hydrological cycle and the rules and institutions that govern today's water allocation policies, the authors develop a modern perspective on water management. Moreover, the book presents an in-depth assessment of the political and ethical dimensions of water management and its institutional embeddedness, by discussing distribution issues and issues of the enforceability of human rights in managing water resources. Given its scope, the book will appeal to advanced undergraduate and graduate students of economics and engineering, as well as practitioners in the water sector, seeking a deeper understanding of economic approaches to the study of water management.

The main objective of the Water Framework Directive in the European countries is to achieve a good status of all the water bodies, in the integrated management of river basins. In order to assess the impact of improvement measures, water quality models are necessary. During the previous decades the progress in computer technology and computational methods has supported the development of advanced mathematical models for pollutant transport in rivers and streams. This book is intended to provide the fundamental knowledge needed for a deeper understanding of these models and the development of new ones, which will fulfil future quality requirements in water resources management. This book focuses on the fundamentals of computational techniques required in water quality modelling.

Advection, dispersion and concentrated sources or sinks of contaminants lead to the formulation of the fundamental differential equation of pollutant transport. Its integration, according to appropriate initial and boundary conditions and with the knowledge of the velocity field, allows for pollutant behaviour to be assessed in the entire water body. An analytical integration is convenient only in one-dimensional approach with considerable simplification. Integration in the numerical field is useful for taking into account particular aspects of water body and pollutants.

To ensure their reliability, the models require accurate calibration and validation, based on proper data, taken from direct measurements. In addition, sensitivity and uncertainty analysis are also of utmost importance.

All the above items are discussed in detail in the 21 chapters of the book, which is written in a didactic form for professionals and students.

Contamination of the different components of environment through industrial and anthropogenic activities have guided new eras of research. This has lead to development of strategies/methodologies to curtail/minimize environmental contamination. Research studies conducted all over the globe established that bioremediation play a promising role in minimizing environmental contamination. In the last decade, phytoremediation studies have been conducted on a vast scale. Initial research in this scenario focused on screening terrestrial plant species that remove contaminants from soil and air. Later, scientific community realized that water is a basic necessity for sustaining life on earth and quality of which is getting deteriorated day by day. This initiated studies on phytoremediation using aquatic plants. Role of aquatic plant species in cleaning water bodies was also explored. Many of the aquatic plant species showed potential to treat domestic, municipal and industrial wastewaters and hence their use in constructed wetlands for treating wastewaters was emphasized. The present book contains five chapters. First two chapters provide information about types of contaminants commonly reported in wastewaters and enlists some important and well studied aquatic plant species known for their potential to remove various contaminants from wastewater. Subsequent chapters deal with mechanisms involved in contaminant removal by aquatic plant species, and also provide detailed information about role of aquatic plant species in wetlands. Potential of constructed wetlands in cleaning domestic and industrial wastewaters has also been discussed in detail. The strategy for enhancing phytoremediation capacity of plants by different means and effectiveness of phytoremediation technology in terms of monitory benefits has been discussed in last chapter. Last chapter also emphasizes the future aspects of this technology.
