Cyanobacteria and their toxins are an increasing global public health menace. Most recently, problems have been experienced in Australia, the United States and, due to drought and increasing water scarcity, pose a severe threat in the U.K. With an international range of contributors, all leading experts in their fields, Toxic Cyanobacteria in Water examines the increasing need to protect drinking water and water resources from the hazards of Cyanobacteria and their impact on health. Written and edited by a World Health Organization working group, Toxic Cyanobacteria in Water is an operational handbook in a practical, assessible style.Toxic Cyanobacteria in Water will be invaluable to environmental health officers, professionals in the fields of water supply, public health, fresh water ecology and education, national and international organizations, special interest groups, post-graduate students and utilities responsible for managing drinking water supplies.

Written by two of the world’s leading experts on sediment management, 'Extending the Life of Reservoirs' provides guidance on adopting sediment management practices for hydropower and water supply dam projects. It explains how ensuring long-term resilience of critical infrastructure requires early and constant attention to reservoir sedimentation processes, which can reduce the storage capacity of reservoirs and damage hydro mechanical equipment. The report provides concrete guidance on safeguarding against these effects and preserving the many important services of hydropower and dam projects, including water supply, irrigation, and renewable electricity. In particular, it stresses the importance of integrating sediment management into the early planning phases of projects. 'Extending the Life of Reservoirs' is designed to assist those evaluating dam and hydropower proposals. While for the primary audience includes policy makers, lending agencies, and general practitioners, the level of detail provided in the report should appeal to a wide array of stakeholder groups. The content is neither overly technical nor overly simplistic, and aims to provide practical and useful information. Importantly, this report provides a new perspective on the importance of sediment management that is not found in prior work. It stresses the value of sediment management measures as a robust adaptation measure to support sustainable hydropower. The techniques described in the report make sense regardless of future climate changes, but in many cases have even more value when uncertainty over future hydrological patterns is taken into account.

Research on reservoir sedimentation in recent years has been aimed mainly at water resources projects in developing countries. These countries, especially in Africa, often have to cope with long droughts, flash floods and severe erosion problems. Large reservoir capacities are required to capture water provided by flash floods so as to ensure the supply of water in periods of drought. The problem arising however is that these floods, due to their tremendous stream power, carry enormous volumes of sediment which, due to the size of reservoirs, are virtually deposited in toto in the reservoir basin, leading to fast deterioration of a costly investment. Accurate forecasting of reservoir behaviour is therefore of the utmost importance.This book fills a gap in current literature by providing in one volume comprehensive coverage of techniques required to practically investigate the effects sediment deposition in reservoirs has on the viability of water resources projects. Current techniques for practically estimating sediment yield from catchments, estimating the volume of sediment expected to deposit in reservoirs, predicting sediment distribution and calculating scour downstream of reservoirs are evaluated and presented. The liberal use of diagrams and graphs to explain the various techniques enhances understanding and makes practical application simple. A major feature of the book is the application of stream power theory to explain the process of reservoir sedimentation and to develop four new methods for predicting sediment distribution in reservoirs.The book is primarily directed at practising engineers involved in the planning and design of water resources projects and at post-graduate students interested in this field of study.

Big dams built for irrigation, power, water supply, and other purposes were among the most potent symbols of economic development for much of the twentieth century. Of late they have become a lightning rod for challenges to this vision of development as something planned by elites with scant regard for environmental and social consequences—especially for the populations that are displaced as their homelands are flooded. In this book, Sanjeev Khagram traces changes in our ideas of what constitutes appropriate development through the shifting transnational dynamics of big dam construction. Khagram tells the story of a growing, but contentious, world society that features novel and increasingly efficacious norms of appropriate behavior in such areas as human rights and environmental protection. The transnational coalitions and networks led by nongovernmental groups that espouse such norms may seem weak in comparison with states, corporations, and such international agencies as the World Bank. Yet they became progressively more effective at altering the policies and practices of these historically more powerful actors and organizations from the 1970s on. Khagram develops these claims in a detailed ethnographic account of the transnational struggles around the Narmada River Valley Dam Projects in central India, a huge complex of thirty large and more than three thousand small dams. He offers further substantiation through a comparative historical analysis of the political economy of big dam projects in India, Brazil, South Africa, and China as well as by examining the changing behavior of international agencies and global companies. The author concludes with a discussion of the World Commission on Dams, an innovative attempt in the late 1990s to generate new norms among conflicting stakeholders.

This book discusses different aspects of water resources, ranging from hydrology and modeling to management and policy responses. Climate changes and the uncertainty of future hydrological regimes make sustainable water resources management a difficult task, requiring a set of approaches that address climate variability and change. The book focuses on three main themes: hydrological changes, adaptive decision-making for water resources, and institutional analysis and risk management. It discusses the applications and limitations of climate change models and scenarios related to precipitation projection, which predicts to the future availability of water. It also offers interesting examples from around the globe to describe the policy options for dealing with climate change. Addressing emerging issues that need to be resolved and techniques that can be applied for sustainable climate-change-sensitive water resources protection and management, this practical, state-of-the-art reference book is a valuable resource for researchers, students and professionals interested in sustainable water resources management in a changing climate.
