Book Description
If present trends continue, most climatologists agree that the concentration of carbon dioxide in the atmosphere will have doubled by the year 2050. This increase in CO 2 will have a major effect on the global climate and substantially alter the physical, chemical and biological characteristics of lakes throughout the world. In recent years, it has become clear that year-to-year changes in the weather have a major effect on the seasonal dynamics of lakes. Many water quality problems that were once regarded as "local" phenomena are now known to be influenced by changes in the weather that operate on a regional or even global scale. For example, blooms of toxic blue-green algae can be induced by prolonged reductions in the intensity of wind-mixing as well as increased supplies of nutrients. Long-term studies in the English Lake District have shown that many of these variations are quasi-cyclical in nature and can be related to long-term changes in the distribution of atmospheric pressure over the Atlantic Ocean. It is not yet clear what effect these changes have on the dynamics of European lakes but much of the historical data required to extend these analyses to continental Europe is already available. In the early 1970s the International Biological Programme served as a particularly effective focus for comparative limnological research in eastern as well as western Europe.

Book Description
To plan successfully and manage the increased uncertainties posed by likely future climate change, knowledge needs to advance much more for the water profession beyond what it is now available. Meeting these challenges does not depend exclusively on advances in climatological-hydrologic models. Policies for adaptation and strategies for mitigation measures have to be formulated on the basis of what are likely to be the potential impacts. These will have to be regularly fine-tuned and implemented according to changing needs and as more reliable knowledge and data become available. Even more challenging will be the politics of policy making and implementation, which will require a quantum leap from current policy-making and implementation processes. One can even say that, in addition to the development of more reliable models, the politics of climate change and water management remains one of the greatest uncertainties for the water profession. This book addresses water management practices and how these should and could be modified to cope with climatic and other related uncertainties over the next two to three decades; the types of strategies and good practices that may be available or have to be developed to cope with the current and expected uncertainties in relation to climate change; and the types of knowledge, information and technological developments needed to incorporate possible future climate change impacts within the framework of water resources management. Decision making in the water sector under changing climate and related uncertainties, and societal water security under altering and fluctuating climate are also discussed. Several case studies are included from several basins, cities, regions and countries in both developed and non-developing countries. This book was published as a special issue of the International Journal of Water Resources Development.

Book Description
Global change possesses serious challenges for water managers and scientists. In mountain areas, where water supplies for half of the world population originate, climate and hydrologic models are still subject to considerable uncertainty. And yet, critical decisions have to be taken to ensure adequate and safe water supplies to billions of people, millions of farmers and industries, without further deteriorating rivers and water bodies. While global warming is known to cause glaciers’ retreat and reduced snow packs around the world, it is not clear that mountain discharge will be lower. What is widely recognised is that water management must be adapted to accommodate significant regime changes. However, this inevitably involves managing transboundary rivers, adding further complexity to putting principles in practice. This book takes global warming and the importance of mountain areas in world water resources as the starting point. First, it provides detailed reviews of the processes going on in several rivers systems and world regions in Europe (Rhône and Ebro), North America (Canadian Rockies, Western US and Mexico), the Middle East (Jordan), Africa (Tunisia, Kenya and South Africa). These contexts provide case studies and examples that show the difficulties and potential for adaptation to global change. Land-use, economics, numerous modeling approaches are some of the cross-cutting issues covered in the chapters. The volume also includes the views of water practitioners, with two chapters authored by members of the US-Canada International Joint Commission, an industrialist from Western Canada and an environmental leader in Spain. By combining a rich set of contexts and approaches, the volume succeeds in offering a view of the global challenges faced by water agencies, international donors and researchers around the world. A case is made in some chapters to seek adaptive strategies rather than trying to reduce or control resources variability. This requires factoring in land-use, social and economic aspects, especially in developing countries. Another conclusion is that complex problems can and must be posed and negotiated with the help of models, mapping techniques and science-based facts. However complex these may be, there are ways to translate them to easily interpretable and visualisations of alternative scenarios and courses of action. This book provides numerous examples of the potential of such approaches to draft environmental programmes solve transboundary disputes and reduce the economic consequences of droughts and climate instability.

Book Description
It has been more than ten years since the last edition of the bestselling Restoration and Management of Lakes and Reservoirs. In that time, lake and reservoir management and restoration technologies have evolved and an enhanced version of this standard resource is long overdue. Completely revised and updated, the third edition continues the tradition of providing comprehensive coverage of the chemical, physical, and biological processes of eutrophication and its control. The authors describe the eutrophication process, outline methods for developing a pre-management and restoration diagnosis-feasibility study, and provide detailed descriptions of scientifically sound management and restoration methods. See what’s new in the Third Edition: • New chapters on aquatic plant ecology and management • Emphasis on freshwater availability • A regional framework for water quality attainment • Methods of lake and reservoir restoration and management • Updates or revisions to all other chapters The book features in-depth discussions of techniques used to manage eutrophication in standing water bodies, procedures for using these techniques, the principles involved, and successes and failures through a selection of case studies and cost analyses. Each chapter includes an introduction to the scientific basis of the problem, a description of the methods and procedures, and presents several case histories. Potential negative impacts and costs, where known, are described. A useful classroom text, reference manual, and general guide, this is the text against which all other resources in this field are measured.

Book Description
In this book, scientists from eleven countries summarize the results of an EU project (CLIME) that explored the effects of observed and projected changes in the climate on the dynamics of lakes in Northern, Western and Central Europe. Historical measurements from eighteen sites were used to compare the seasonal dynamics of the lakes and to assess their sensitivity to local, regional and global-scale changes in the weather. Simulations using a common set of water quality models, perturbed by six climate-change scenarios, were then used to assess the uncertainties associated with the projected changes in the climate. The book includes chapters on the phenology and modelling of lake ice, the supply and recycling of nitrogen and phosphorus, the flux of dissolved organic carbon and the growth and the seasonal succession of phytoplankton. There are also chapters on the coherent responses of lakes to changes in the circulation of the atmosphere, the development of a web-based Decision Support System and the implications of climate change for the Water Framework Directive.

Book Description
Continuing concern about water supply and quality, ecosystem sustainability and restoration demands that the modern approach to the management of lakes and reservoirs should be based on a sound understanding of the application of the scientific and ecological principles that underlie freshwater processes. The Lakes Handbook provides an up-to-date overview of the application of ecologically sound approaches, methods and tools using experience gained around the world for an understanding of lakes and their management. Volume one of the Handbook addresses the physical and biological aspects of lakes pertinent to lake management, emphasising those aspects particularly relevant to large, still bodies of water. Volume two then considers lake management, with particular emphasis on sustainability, restoration and rehabilitation. This handbook will be invaluable to ecologists, environmental scientists, physical geographers and hydrologists involved in limnological research, as well as advanced undergraduate and graduate students looking for authoritative reviews of the key areas of limnological study.

Book Description
Most aquatic ecosystems have variable water levels. These water-level fluctuations (WLF) have multiple effects on the organisms above and below the waterline. Natural WLF patterns in lakes guarantee both productivity and biodiversity, while untimely floods and droughts may have negative effects. Human impacts on WLF have led to a stabilization of the water levels of many lakes by hydraulic regulation, untimely drawdown due to water use, or floods due to water release from hydropower plants in the catchments. This book provides a first review in this field. It presents selected papers on the ecological effects of WLF in lakes, resulting from a workshop at the University of Konstanz in winter 2005. Issues addressed here include the extent of WLF, and analyses of their effects on different groups of biota from microorganisms to vertebrates. Applied issues include recommendations for the hydrological management of regulated lakes to reduce negative impacts, and a conceptual framework is delivered by an extension of the floodpulse concept for lakes. Current impacts on water use, including increasing demands on drinking and irrigation water, hydropower etc., and climate change effects on WLF make this book an essential resource for aquatic ecologists, engineers, and decision-makers dealing with the management of lake ecosystems and their catchments.

Book Description
Lake and Reservoir Restoration deals with the eutrophication process and the methods to protect, restore, and manage lakes and reservoirs. The most common in-lake techniques or procedures, plus nutrient diversion, are reviewed with regard to their scientific basis, methods of application, known effectiveness, feasibility, drawbacks, and costs. Areas for further research and development are also highlighted. This book is comprised of 16 chapters organized into four sections. After an introduction to the theory of the problem and the restoration technique, the discussion turns to the various restoration methods such as those used for physical and chemical control of nutrients. Diversion and advanced waste treatment, hypolimnetic withdrawal, and dilution and flushing are considered along with phosphorus precipitation and inactivation, sediment oxidation, sediment removal, and hypolimnetic aeration. Case studies and success stories are presented and the costs and potential negative impacts of the methods are examined. The following chapters focus on methods to control plant biomass, including artificial circulation, water-level drawdown, harvesting, biological control, and surface and sediment covers. A chapter on liming acidified lakes concludes this text. This monograph will be useful to professional limnologists and engineers, on-site lake or reservoir managers, and those who are interested in learning about the problems and management of lakes and reservoirs.
