The supply and management of fresh water for the world's billions of inhabitants is likely to be one of the most daunting challenges of the coming century. For countries that share river basins with others, questions of how best to use and protect precious water resources always become entangled in complex political, legal, environmental, and economic considerations. This book focuses on the issues that face all international river basins by examining in detail the Nile Basin and the ten countries that lay claim to its waters.

John Waterbury applies collective action theory and international relations theory to the challenges of the ten Nile nations. Confronting issues ranging from food security and famine prevention to political stability, these countries have yet to arrive at a comprehensive understanding of how to manage the Nile's resources. Waterbury proposes a series of steps leading to the formulation of environmentally sound policies and regulations by individual states, the establishment of accords among groups of states, and the critical participation of third-party sources of funding like the World Bank. He concludes that if there is to be a solution to the dilemmas of the Nile Basin countries, it must be based upon contractual understandings, brokered by third-party funders, and based on the national interests of each basin state.

A set of conservation and restoration practices, and a review of protected sites within the Polish basins and catchment areas, are also provided. This book and the companion volume Polish River Basins and Lakes - Part I: Hydrology and Hydrochemistry offer valuable resources for students, environmental chemists, biologists, geologists, hydrologists and surface waters managers interested in the environmental conditions of Poland's surface waters.

India has 7,500 km of coastline with diverse habitats and rich biota. Coastal ecosystems, unfortunately, are experiencing wide range of pressures due to siltation, eutrophication, coastal development, aquaculture and climate change. Those species that adapt to these pressures will expand their living boundaries while others may fade away. Accordingly, the study of coastal biodiversity is of great concern globally and constitutes an important element of global change research. Gujarat has 1,600 km of coastline, reportedly with rich diversity of seaweeds. Previously published accounts on seaweed biodiversity were mainly in the form of checklists, the earliest among these being the checklist of Krishnamurthy and Joshi prepared in the early 1970s. The more recent checklists are based almost entirely on secondary information. The present book entitled Seaweeds of India - The Diversity and Distribution of Seaweeds of Gujarat Coast is a timely publication based wholly on primary data. Data were collected through extensive and systematic ? eld studies conducted by the authors during different seasons over a three year period. The authors collected nearly 200 species of seaweeds belonging to 100 genera of Chlorophyta, Phaeophyta and Rhodophyta. Twenty-four of the species are new to Gujarat coast and three are new to Indian waters. The book contains high-quality images of the different species in their existing habitats. Brief taxonomical descriptions, together with information on ecology, distribution, seasonality and abundance, are covered for each of the species.

The oceans cover over 70% of our planet. They are host to a biodiversity of tremendous wealth. Its preservation is now a global priority featuring in several international conventions and a confirmed objective of European policies and national strategies. Understanding the dynamics and the uses of the marine biodiversity is a genuine scientific challenge. Fourteen international experts have got together and identified five priority research themes to address the problem, based on analysing the state of knowledge.

Tidal freshwater forested wetlands are unique wetland systems. Occupying low relief coastal areas which are subject to both upland runoff and tidal flooding, these systems are especially vulnerable to pressure from human development and to climate change impacts of sea-level rise and increased drought/flood frequency. Yet to date the ecological dynamics, distribution, and conservation status of these communities is poorly understood.This book draws together the latest findings from investigators focusing on the hydrological processes, community organization, and stress physiology of freshwater, tidally influenced land-margin forests of the southeastern United States. It describes the land use history that led to the restricted distribution of these wetlands, and provides descriptions of the hydrology, soils, biogeochemistry, and physiological ecology of these systems, highlighting the similarities shared among tidal freshwater forested wetlands.

This volume is of great importance to humans and other living organisms. The study of water quality draws information from a variety of disciplines including chemistry, biology, mathematics, physics, engineering, and resource management. University training in water quality is often limited to specialized courses in engineering, ecology, and fisheries curricula. This book also offers a basic understanding of water quality to professionals who are not formally trained in the subject. The revised third edition updates and expands the discussion, and incorporates additional figures and illustrative problems. Improvements include a new chapter on basic chemistry, a more comprehensive chapter on hydrology, and an updated chapter on regulations and standards. Because it employs only first-year college-level chemistry and very basic physics, the book is well-suited as the foundation for a general introductory course in water quality. It is equally useful as a guide for self-study and an in-depth resource for general readers.

This book provides a broad overview of how the promotion of ocean and coastal literacy is being planned, applied and evaluated in Brazil, a country of continental dimensions with a great diversity of cultural, educational and social realities. It discusses a range of target groups, from children to adults; formal and informal strategies; and various promoting players, such as groups/institutions. Researchers representing Brazilian academic institutions and NGOs share their environmental education (EE) experiences in Brazil and describe the main concerns regarding the marine and coastal environments as well as how they are addressing these concerns in their EE projects. This book is of interest to anyone who is looking for ways of designing and implementing EE activities with a robust theoretical background in different socio-cultural scenarios.

It is organised both thematically and by region, with the sea floor and its biological hotspots - areas of high biodiversity such as seamounts - shown at a resolution not possible before. The atlas presents everything from submarine canyons to coral carbonate mounds, using digital terrain models generated from multibeam data and photographs taken from unmanned deep-water vehicles (ROVs).

The full-colour imagery includes digital three-dimensional seabed maps as well as the photographs, with concise text descriptions and topic boxes used to highlight and explain the geological, biological and hydrographical features, in addition to their importance and context in the deep-sea realm. Alongside the wealth of background information and topic boxes on special highlights, extensive on-line resources link the reader to full data sets and GIS locations, while suggestions for further reading point to ongoing research highlights. This is a fascinating resource that will be of use to anyone involved in off-shore and underwater activities, whether scientific or commercial.

Winner of the Marsh Book of the Year Award (2015) Throughout British history rivers have been of profound economic, social and cultural importance - yet as we see with increasing frequency they have the potential to wreak great destruction. This book describes the natural and not-so-natural changes that have affected British rivers since the last ice age and looks at the many plants and animals that live along, above and within them. Detailed case studies of the Meon, Dee and Endrick illustrate the incredibly varied nature of our river ecosystems, and the natural and human factors that make each one different. Written by two widely respected river ecologists, the book looks not only at rivers as they were and are but also at how they can be managed and cared for. Full of interesting facts and stunning images, Rivers is essential reading for anyone professionally involved in rivers and for the naturalist, conservationist and layman alike. It is the one book you need to understand this singularly important and often contentious feature of the British landscape.

Part travelogue, part history, and part environmental treatise, "Mekong - The Occluding River" is above all else an urgent warning that factors such as pollution, ecological devastation, and the depletion of natural resources are threatening the very existence of the Mekong River. Author Ngo The Vinh combines his vivid travel notes and collection of photographs with a meticulously researched history of the environmental degradation of the Mekong River. Translated from Vietnamese, the best-selling treatise outlines the myriad threats facing the river today. From oil shipments feeding the industrial cities of southwestern China to gigantic hydroelectric dams known as the Mekong Cascades in Yunnan province, China is the worst environmental offender, though the other nations along Mekong's banks behave no better. From Thailand to Laos to Vietnam, hydroelectric dams that threaten the Mekong and its inhabitants are being built at an alarming rate. To save the Mekong, Ngo The Vinh calls upon all the nations that benefit from its life-giving water to observe the "Spirit of the Mekong" in the implementation of all future development projects. To achieve this end, there must be a concerted and sustained commitment to cooperation and sustainability. At this critical cross-roads, we should remind ourselves of the mantra from Sea World San Diego: "Extinction is forever. Endangered means we still have time."

The Rhine is one of Europe 's most researched rivers and this book presents a compilation of that research in one volume. Topics include the river 's catchment area, its hydrology, the development of water protection requirements and early warning systems on the Rhine. Additionally the book describes many aspects of water quality from the Rhine but also from alpine lakes, tributaries, estuary and adjacent coastal waters connected with the river.

In a rapidly evolving world of knowledge and technology, do you ever wonder how hydrology is catching up? This book takes the angle of computational hydrology and envisions one of the future directions, namely, quantitative integration of high-quality hydrologic field data with geologic, hydrologic, chemical, atmospheric, and biological information to characterize and predict natural systems in hydrological sciences.

Intelligent computation and information fusion are the key words. The aim is to provide both established scientists and graduate students with a summary of recent developments in this topic. The chapters of this edited volume cover some of the most important ingredients for quantitative hydrological information fusion, including data fusion techniques, interactive computational environments, and supporting mathematical and numerical methods. Real-life applications of hydrological information fusion are also addressed.

This book provides an introductory understanding of fluvial geomorphic principles and how these principles can be integrated with geochemical data to cost-effectively characterize, assess and remediate contaminated rivers. The book stresses the importance of needing to understand both geomorphic and geochemical processes. Thus, the overall presentation is first an analysis of physical and chemical processes and, second, a discussion of how an understanding of these processes can be applied to specific aspects of site assessment and remediation. Such analyses provide the basis for a realistic prediction of the kinds of environmental responses that might be expected, for example, during future changes in climate or land-use.

This book presents the latest developments and recent research trends in the field of plankton, highlighting the potential ecological and biotechnological applications. It critically and comprehensively discusses strain selection, growth characteristics, large-scale culturing, and biomass harvesting, focusing on the screening and production of high-value products from algae, and evaluating carbon dioxide sequestration from fuel gas as a climate change mitigation strategy. The latter areas of research are clearly central to the sustainable development approach that is currently attracting global attention. Over the decades, much of the literature on has focused on the biological and ecological aspects of phytoplankton found in freshwater, marine and brackish water environments. However, these organisms are known to also inhabit various other environments. More recently, there has been a substantial shift toward the concept of sustainable development and the "green economy" with emphasis on exploiting biological systems for the benefit of mankind. The significance of these plankton cannot be underestimated as they contribute approximately 40% of the oxygen in the atmosphere. Therefore, there is potential for exploitation of this invaluable biomass source that could lead to significant environmental and economic benefits for man. Providing a comprehensive outline of the most recent developments and advances in the field of industrial applications of these plankton, this book is an excellent reference resource for researchers and practitioners.

One of the major questions in the evolution of animals is the transition from unicellular to multicellular organization, which resulted in the emergence of Metazoa through a hypothetical Urmetazoa. The Comparative Embryology of Sponges contains abundant original and literary data on comparative embryology and morphology of the Porifera (Sponges), a group of 'lower Metazoa'. On the basis of this material, original typization of the development of Sponges is given and the problems concerning origin and evolution of Porifera and their ontogenesis are discussed. A morphogenetic interpretation of the body plan development during embryogenesis, metamorphosis and asexual reproduction in Sponges is proposed. Special attention is given to the analysis of characteristic features of the ontogenesis in Porifera. The book pursues three primary goals: 1) generalization of all existing information on individual development of sponges, its classification and a statement according to taxonomical structure of Porifera; 2) revealing of heterogeneity of morphogenesis and peculiarities of ontogeneses in various clades of Porifera, and also their correlations with the organization, both adult sponges, and their larvae; 3) revealing homology of morphogeneses in both Porifera and Eumetazoa, testifying to the general evolutionary roots of multicellular animals, and peculiar features of sponges' morphogeneses and ontogenesis. This book will be of interest to embryologists, zoologists, morphologists and researchers in evolutionary biology.

Delphus E. Carpenter (1877-1951) was Colorado's commissioner of interstate streams during a time when water rights were a legal battleground for western states. A complex, unassuming man as rare and cunning in politics and law as the elusive silver fox of the Rocky Mountain West, Carpenter boldly relied on negotiation instead of endless litigation to forge agreements among states first, before federal intervention. In Silver Fox of the Rockies, Daniel Tyler tells Carpenter's story and that of the great interstate water compacts he helped create. Those compacts, produced in the early twentieth century, have guided not only agricultural use but urban growth and development throughout much of the American West to this day. In Carpenter's time, most western states relied on the doctrine of prior appropriation--first in time, first in right--which granted exclusive use of resources to those who claimed them first, regardless of common needs. Carpenter feared that population growth and rapid agricultural development in states sharing the same river basins would rob Colorado of its right to a fair share of water. To avoid that eventuality, Carpenter invoked the compact clause of the U.S. Constitution, a clause previously used to settle boundary disputes, and applied it to interstate water rights. The result was a mechanism by which complex issues involving interstate water rights could be settled through negotiation without litigating them before the U.S. Supreme Court. Carpenter believed in the preservation of states' rights in order to preserve the constitutionally mandated balance between state and federal authority. Today, water remains critically important to the American West, and thegreat interstate water compacts Carpenter helped engineer constitute his most enduring legacy. Of particular significance is the Colorado River Compact of 1922, without which Hoover Dam could never have been built.

Most of the time series analysis methods applied today rely heavily on the key assumptions of linearity, Gaussianity and stationarity. Natural time series, including hydrologic, climatic and environmental time series, which satisfy these assumptions seem to be the exception rather than the rule. Nevertheless, most time series analysis is performed using standard methods after relaxing the required conditions one way or another, in the hope that the departure from these assumptions is not large enough to affect the result of the analysis. A large amount of data is available today after almost a century of intensive data collection of various natural time series. In addition to a few older data series such as sunspot numbers, sea surface temperatures, etc., data obtained through dating techniques (tree-ring data, ice core data, geological and marine deposits, etc.), are available. With the advent of powerful computers, the use of simplified methods can no longer be justified, especially with the success of these methods in explaining the inherent variability in natural time series. This book presents a number of new techniques that have been discussed in the literature during the last two decades concerning the investigation of stationarity, linearity and Gaussianity of hydrologic and environmental times series. These techniques cover different approaches for assessing nonstationarity, ranging from time domain analysis, to frequency domain analysis, to the combined time-frequency and time-scale analyses, to segmentation analysis, in addition to formal statistical tests of linearity and Gaussianity. It is hoped that this endeavor would facilitate further research into this important area.

Lake Issyk-Kul is a closed lake located in the Tien Shan mountain belt of the Republic of Kyrgyzstan. It is the world's fifth deepest lake (668 m) and the second largest high altitude lake in the world (1607 m above sea level). The lake is affected by several environmental threats of both anthropogenic and natural origin: decline of the lake level resulting in progressively increasing salinity, incomplete vertical water exchange, and risk of contamination by past and present industrial activity.
Although the lake has been intensively studied, the information is only available in unpublished reports or local scientific journals. This book presents for the first time to an international audience the main physical, chemical, biological and geological characteristics of the lake, the fruits of many years of observations, complemented by recent results of international projects. Case studies of similar problems in other parts of the world are presented, together with ethical aspects of the environmental protection of the lake.

Large lakes are important because of their size and ecological distinctiveness as well as their economic and cultural value. Optimal management of them requires a proper understanding of anthropogenic impacts both on the lake ecosystems as such and on the services they provide for society. The specific structural and functional properties of large lakes, e.g. morphology, hydrography, biogeochemical cycles and food-web structure, are all directly related to their size. Although large lakes are among the best-studied ecosystems in the world, the application to them of environmental regulations such as the European Water Framework Directive is a challenging task and requires that several natural and management aspects specific to these water bodies are adequately considered. These vulnerable ecosystems often suffer from accelerated eutrophication, over-fishing, toxic contamination and invasive species. Large lakes offer socio-economic benefits and can be used in many ways, and are often areas in which economic, cultural and political interests overlap. In this book the problems regarding the present status of European large lakes and the directions of change are discussed. Threats caused by direct human impact and by climate change, protection needs and restoration measures are considered.

The four volumes in this set cover major aspects of hydrology and water resources, including surface water hydrology, subsurface water hydrology, water quality hydrology, and water resources planning management. The books reflect the water resources technology as practised in India and the Indian subcontinent which should be of value to water resources professionals in the West. The books should be of interest to academicians, graduate students, practising engineers, water engineers, as well as water policy makers.

This volume presents recent advances in the research on meromictic lakes and a state-of-the art overview of this area. After an introduction to the terminology and geographic distribution of meromictic lakes, three concise chapters describe their physical, chemical and biological features. The following eight chapters present case studies of more than a dozen meromictic lakes, showing the variety of physical and biochemical processes that promote meromixis. The result is a broad picture of the ecology and biochemistry of meromictic lakes in tropical and cold regions, in man-made pit lakes and euxinic marine lakes, and in freshwater as well as hypersaline lakes. In the final chapter the editors provide a synthesis of the topic and conclude that the study of meromictic lakes also offers new insights into the limnology of inland lakes. The book appeals to researchers in the fields of ecology, limnology, environmental physics and biophysics.
