Book Description
One of the main challenges faced by humans today is finding a balance between economic development of respective countries and sustainable utilisation of Earths resources. With the increase in the human population, demand for water resources is increasing globally. One of the challenges for water conservation in the future is the sustainability of current and future water resource allocation. Finding a balance between what is needed by humans and what is needed in the environment is an important step in the sustainability of water resources. With this in mind, sustainable utilisation of water resources, and conservation and management of aquatic ecosystems on Earth is an essential step towards the sustainable management of global water resources. This book discusses the current status of water resources on Earth and challenges water resource conservation in the first chapter. The second chapter of the book describes the physical, chemical and biological properties of water, and the biological indicators that can be used as water quality indicators. The third chapter of the book discusses how water becomes polluted, factors contributing to water pollution, as well as types and sources of water pollutants. The fourth chapter discusses the importance of water quality monitoring programmes and the methods of water quality monitoring programmes. Chapters Five and Six discuss the characteristics of lotic and lentic systems, factors affecting lotic and lentic systems and possible management options for each category. Chapter Seven discusses the aspects related to watershed management and water pollution control. The final chapter discusses agricultural and urban watershed management options, common issues related to their management, and strategies to reduce waste generation and pollution control.

Book Description
In this concise introduction to water resources, Shimon Anisfeld explores the fundamental interactions between humans and water, including drinking, sanitation, irrigation, and power production. The book familiarizes students with the current water crisis and with approaches for managing this essential resource more effectively in a time of rapid environmental and social change. Anisfeld addresses both human and ecological problems, including scarcity, pollution, disease, flooding, conflicts over water, and degradation of aquatic ecosystems. In addition to providing the background necessary to understand each of these problems, the book discusses ways to move towards better management and addresses the key current debates in the water policy field. In the past, water development has often proceeded in a single-sector fashion, with each group of users implementing its own plans without coordination with other groups, resulting in both conflict and inefficiency. Now, Anisfeld writes, the challenge of water management is figuring out how to balance all the different demands for water, from sanitation to energy generation to ecosystem protection. For inquiring students of any level, Water Resources provides a comprehensive one-volume guide to a complex but vital field of study.

Book Description
This classroom resource provides clear, concise scientific information in an understandable and enjoyable way about water and aquatic life. Spanning the hydrologic cycle from rain to watersheds, aquifers to springs, rivers to estuaries, ample illustrations promote understanding of important concepts and clarify major ideas. Aquatic science is covered comprehensively, with relevant principles of chemistry, physics, geology, geography, ecology, and biology included throughout the text. Emphasizing water sustainability and conservation, the book tells us what we can do personally to conserve for the future and presents job and volunteer opportunities in the hope that some students will pursue careers in aquatic science. Texas Aquatic Science, originally developed as part of a multi-faceted education project for middle and high school students, can also be used at the college level for non-science majors, in the home-school environment, and by anyone who educates kids about nature and water.

Book Description
In order to confront the increasingly severe water problems faced by all parts of the country, the United States needs to make a new commitment to research on water resources. A new mechanism is needed to coordinate water research currently fragmented among nearly 20 federal agencies. Given the competition for water among farmers, communities, aquatic ecosystems and other users-as well as emerging challenges such as climate change and the threat of waterborne diseases-Confronting the Nation's Water Problems concludes that an additional $70 million in federal funding should go annually to water research. Funding should go specifically to the areas of water demand and use, water supply augmentation, and other institutional research topics. The book notes that overall federal funding for water research has been stagnant in real terms for the past 30 years and that the portion dedicated to research on water use and social science topics has declined considerably.

Book Description
The world faces huge challenges for water as population continues to grow, as emerging economies develop and as climate change alters the global and local water cycle. There are major questions to be answered about how we supply water in a sustainable and safe manner to fulfil our needs, while at the same time protecting vulnerable ecosystems from disaster. Water Resources: An Integrated Approach provides students with a comprehensive overview of both natural and socio-economic processes associated with water. The book contains chapters written by 20 specialist contributors, providing expert depth of coverage to topics. The text guides the reader through the topic of water starting with its unique properties and moving through environmental processes and human impacts upon them including the changing water cycle, water movement in river basins, water quality, groundwater and aquatic ecosystems. The book then covers management strategies for water resources, water treatment and re-use, and the role of water in human health before covering water economics and water conflict. The text concludes with a chapter that examines new concepts such as virtual water that help us understand current and future water resource use and availability across interconnected local and global scales. This book provides a novel interdisciplinary approach to water in a changing world, from an environmental change perspective and inter-related social, political and economic dimensions. It includes global examples from both the developing and developed world. Each chapter is supplemented with boxed case studies, end of chapter questions, and further reading, as well as a glossary of terms. The text is richly illustrated throughout with over 150 full colour diagrams and photos.

Book Description
Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.
