This illustrated introduction to Central American Chironomidae offers extensive photographic material, as well as detailed morphological and ecological descriptions of chironomid subfossils found in Central American lake sediments. The book uniquely provides two identification keys: one for living larvae occurring (or potentially being present) in Central America and one for the recorded subfossil remains, using limited morphological characters. Paleolimnological investigations using chironomid remains have undergone a resurgence of interest, and this taxonomic guide will aid the thorough analysis of the diversity and distribution of the taxa encountered to date in Central America. Out of the total 64 described genera, the book brings 20 endemic genera, and more than half of the presented morphotypes are new. Plates are included for each taxon with generic characters and also provide a key to morphotypes, if present, their specific characters, distribution, and ecology. Authored by a (paleo)limnologist and a taxonomist, the guide draws on a thorough taxonomical knowledge of the region's recent chironomid fauna. It uses a paleolimnological approach to transmit this information to morphotypes that can be linked with ecology and used to reconstruct the past development of nature. The book thus helps paleo-workers and taxonomists to learn more about these fascinating insects and, through them, to discover the world around us. Providing a comprehensive reference for aquatic ecologists, paleolimnologists, students, and researchers, the guide will also be of interest to non-academic professionals working on applied research and biomonitoring of lakes. It will be useful for people studying both recent and subfossil material, not only in Central America, but in the whole Neotropical region.

Recent contributions have significantly enhanced the understanding of the SCS-CN method and consequently its application potential. In the simplest form, the fundamental proportionality concept of the method relates the two orthogonal hydrological processes of surface water and ground water and the other hypothesis relates to the atmospheric process. Qualitatively, the method broadly integrates all the three major processes of the hydrologic cycle; and therefore it can form one of the fundamental concepts of hydrology. This textbook is aimed at presenting an up-to-date account of the SCS-CN method and clarify its potential for practical applications, and especially those other than originally intended.

The subject matter of the book is divided into nine chapters, treating the following topics: a brief introduction of rainfall-runoff modeling and elements of catchment, precipitation, interception, surface detention and depression storage, evaporation, infiltration, runoff, and the runoff hydrograph; the factors affecting the curve number (CN), the determination of CN, the use of NEH-4 tables, sensitivity analysis, advantages and limitations of the SCS-CN method, and application to distributed watershed modeling; an analytical derivation of the SCS-CN method focusing on the Mockus and other methods; a determination of S' using the volumetric concept encompassing an analytical derivation, verification of the existing AMC criteria, determination of S, use of NEH-4 tables and advantages and limitations of the modified model; the determination of S' using physical principles, involving Fokker-Planck equation of infiltration, description of S, S/P relations for the modified model anddetermination of Ds from universal soil loss equation; simulation of infiltration and runoff hydrographs, with particular emphasis on SCS-CN-based infiltration and runoff models and application of infiltration and runoff models; long-term hydrologic simulation and hydrologic models of Williams and LaSeur, Hawkins, Pandit and Gopalkrishnan, and Mishra and others; rainfall-excess computation, soil moisture budgeting, catchment routing, and baseflow computation; transport of pollutants in urban watersheds; and sediment yield.

Audience: This volume will be of interest to agricultural scientists, agricultural and civil engineers, environmental engineers, forest and range scientists, as well as watershed managers. It will also be useful to college students and faculty members engaged in environment and water related studies.

The Ganges is one of the most complex yet fascinating river systems in the world. The basin is characterized by a high degree of heterogeneity from climatic, hydrological, geomorphological, cultural, environmental and socio-economic perspectives. More than 500 million people are directly or indirectly dependent upon the Ganges River Basin, which spans China, Nepal, India and Bangladesh. While there are many books covering one aspect of the Ganges, ranging from hydrology to cultural significance, this book is unique in presenting a comprehensive inter-disciplinary overview of the key issues and challenges facing the region. Contributors from the three main riparian nations assess the status and trends of water resources, including the Himalayas, groundwater, pollution, floods, drought and climate change. They describe livelihood systems in the basin, and the social, economic, geopolitical and institutional constraints, including transboundary disputes, to achieving productive, sustainable and equitable water access. Management of the main water-use sectors and their inter-linkages are reviewed, as well as the sustainability and trade-offs in conservation of natural systems and resource development such as for hydropower or agriculture.

From perpetually snow-capped peaks to stifling deserts below sea-level, the Colorado cuts the deepest and truest cross-section through the heart of the continent.It flows through time as well as space. At the bottom of the Grand Canyon lies one of the early layers of the earth's crust. The cliff dwellers' civilization, and the rise and fall of the great pueblos were only a brief moment in its history. Later came the Spaniards, and then the trappers and prospectors. Not so long ago the Indians battled to defend their invaded country and new technological developments--the greatest is which is Boulder Dam--are beginning to change the face of a region other generations were unable to alter. Frank Waters, a native to Colorado, has brought to his book an understanding of the relation between man and nature which is part of his Indian heritage.

How much water does the world need to support growing human populations? What factors influence water quality, droughts, floods, and waterborne diseases? What are the potential effects of climate change on the world's water resources? These questions and more are discussed in this thorough introduction to the complex world of water resources. The strength of the book is its coverage of the fundamentals of the science of water, aquatic ecology, geomorphology and hydrology, supplemented by internet resources and examples from water resource issues in the news to engage the student. The book begins with a short history of human use and influence on water, followed by chapters on the geomorphology, hydrology, chemistry, and biology of lakes, rivers, and wetlands. Major disease issues, worldwide water quality and quantity problems, and potential solutions are addressed. Water laws, water allocation, and the conflicts involved are discussed using US and international examples. Students in departments of environmental studies, life science, Earth science, and engineering will benefit from this broad survey of these crucial issues.

This book presents a comprehensive survey about the most recent developments in industrial applications, processing techniques and modifications of polymers from marine sources. It systematically introduces the reader to the biomaterials Chitin, Collagen, Alginates, Cellulose and Polyesters and links their interwoven industrial significance and environmental implications. The book elucidates the impact of industrial sourcing of the aquatic system for organic and inorganic matter on the environment and deepens the understanding of the industrial and economic significance of aquatic biopolymers. Further it addresses the question of how to balance the conservation of aquatic life and the industrial and economic interest in developing biodegradable alternatives for plastic. Thus the book will appeal to scientists in the field of chemistry, materials and polymer science as well as engineering.

Until recently, focus on groundwater mainly concerned its use as drinking water and as an important resource for industry (e.g. cooling waters) and agriculture (irrigation). It has, however, become increasingly obvious that groundwater should not only be viewed as a drinking water reservoir, but that it should also be protected for its environmental value. In this respect, groundwater represents an important link of the hydrological cycle through the maintenance of wetlands and river flows, acting as a buffer through dry periods. Hence, deterioration of groundwater quality may directly affect other related aquatic and terrestrial ecosystems. The groundwater legislative framework under the EU Water Framework Directive and the newly adopted Groundwater Directive establishes criteria linked to environmental objectives which have to be met by 2015 following successive operational steps including characterisation, risk assessment (analysis of pressures and impacts), monitoring and design of programmes of measures. These milestones require that sound technical and scientific information be made accessible to water managers, which is so far still not sufficiently streamlined. In this context, this book describes the groundwater legislative milestones and presents series of research and development activities that aim to directly support them. It has, therefore, the ambition to become a vehicle liaising policy requirements and available scientific knowledge in this area.

As they provide a negotiating space for a diversity of interests, Multi-Stakeholder Platforms (MSPs) are an increasingly popular mode of involving civil society in resource management decisions. This book focuses on water management to take a positive, if critical, look at this phenomenon. Illustrated by a wide geographical range of case studies from both developed and developing worlds, it recognizes that MSPs will neither automatically break down divides nor bring actors to the table on an equal footing, and argues that MSPs may in some cases do more harm than good. The volume then examines how MSPs can make a difference and how they might successfully co-opt the public, private and civil-society sectors. The book highlights the particular difficulties of MSPs when dealing with integrated water management programmes, explaining how MSPs are most successful at a less complex and more local level. It finally questions whether MSPs are - or can be - sustainable, and puts forward suggestions for improving their durability.

The revitalizing and restoration of rivers, creeks and streams is a major focus of urban conservation activity throughout North America and Europe. This book presents models and examples for organizing multiple stakeholders for purposes of waterway revitalization-if not restoration-within a context of fairness and environmental justice. After decades of neglect and misuse the challenge of cleaning up urban rivers and streams is shown to be complex and truly daunting. Urban river cleanup typically involves multiple agendas and stakeholders, as well as complicated technical issues. It is also often the situation that the most affected have the least voice in what happens. The authors present social process models for maximum inclusion of various stakeholders in decision-making for urban waterway regeneration. A range of examples is presented, drawn principally from North America and Europe.

Pollutant Effects in Freshwater provides a practical and concise introduction to the ecological consequences of water pollution in aquatic ecosystems.

The new research ideas put forward in groundwater modelling will assist decision makers in tackling challenging problems such as controlling pollution of underground aquifers and obtaining adequate water supplies. Additionally, different types of stochastic models are used in modelling a range of interesting surface water problems. Other topics covered in this landmark volume include stochastic optimization, moment analysis, carbon dioxide modelling and rainfall prediction. Audience: The book is of interest to researchers, teachers, students and practitioners who wish to be at the leading edge of stochastic and statistical modelling in the environmental sciences.

Water is a precious natural resource, which is crucial to our survival. It needs to be used judiciously in the context of an increasing population not only to sustain essential requirements such as those for drinking and domestic usage, but also for increased food production, industrial usage, power generation, navigational requirements, pisciculture, recreation, landscaping etc. There are many books dealing with hydrology, hydraulics and hydraulic structures, which generally deal with larger problems of development, analysis, design and implementation of water resources. However, there are few books, which deal with small-scale development of water resources consistent with the environmental concerns as well as application of relevant eco-friendly technologies. This book provides both the perspectives.

Flooding accounts for one-third of natural disasters worldwide and for over half the deaths that occur as a result of natural disasters. As the frequency and volume of flooding increases, due to climate change, there is a new urgency amongst researchers and professionals working in flood risk management. River Basin Modelling for Flood Risk Mitigation brings together thirty edited papers by leading experts who gathered for the European Union's Advanced Study Course at the University of Birmingham, UK. In this book, coverage ranges in scope from issues concerning the protection of life to river restoration and wetland management. Eminent experts examine a variety of topics, including climate change, hydroinformatics, hydrometeorology, river flow forecasting systems, and dam-break modeling. They also explore risk and uncertainty issues for flood management, the social and economic impacts of flooding, and developments in flood forecasting and early warning systems. Case studies illustrate the concepts and methods presented throughout the text. With broad yet integrated coverage, River Basin Modelling for Flood Risk Mitigation is an informative and accessible reference tool for professional engineers involved with flood risk management.

Modern hydrology is more interdisciplinary than ever. Staggering amounts and varieties of information pour in from GIS and remote sensing systems every day, and this information must be collected, interpreted, and shared efficiently. Hydroinformatics: Data Integrative Approaches in Computation, Analysis, and Modeling introduces the tools, approaches, and system considerations necessary to take full advantage of the abundant hydrological data available today. Linking hydrological science with computer engineering, networking, and database science, this book lays a pedagogical foundation in the concepts underlying developments in hydroinformatics. It begins with an introduction to data representation through Unified Modeling Language (UML), followed by digital libraries, metadata, the basics of data models, and Modelshed, a new hydrological data model. Building on this platform, the book discusses integrating and managing diverse data in large datasets, data communication issues such as XML and Grid computing, the basic principles of data processing and analysis including feature extraction and spatial registration, and modern methods of soft computing such as neural networks and genetic algorithms. Today, hydrological data are increasingly rich, complex, and multidimensional. Providing a thorough compendium of techniques and methodologies, Hydroinformatics: Data Integrative Approaches in Computation, Analysis, and Modeling is the first reference to supply the tools necessary to confront these challenges successfully.

The Rouge River is a mostly urbanized watershed of about 500 square miles populated by nearly 1.4 million people. While not geographically large, the river has played an outsized role in the history of southeast Michigan, most famously housing Ford's massive Rouge Factory, designed by architect Albert Kahn and later memorialized in Diego Rivera's renowned "Detroit Industry" murals. In recent decades, the story of the Rouge River has also been one of grassroots environmental activism. After pollution from the Ford complex and neighboring factories literally caused the river to catch on fire in 1969, community groups launched a Herculean effort to restore and protect the watershed. Today the Rouge stands as one of the most successful examples of urban river revival in the country. Rouge River Revived describes the river's history from pre-European times into the 21st century. Chapters cover topics such as Native American life on the Rouge; indigenous flora and fauna over time; the river's role in the founding of local cities; its key involvement in Detroit's urban development and intensive industrialization; and the dramatic clean-up arising from citizen concern and activism. This book is not only a history of the environment of the Rouge River, but also of the complex and evolving relationship between humans and natural spaces.

The latest developments regarding the theory and practice of effectively resolving conflict in water resources and environmental management are presented in this book by respected experts from around the globe. Water conflicts are particularly complex and challenging to solve because water and environmental issues span both the societal realm, in which people and organizations interact, and the physical world which sustains all human activities. For instance, when large-scale water diversions take place across political jurisdictions, conflicts may ensue among stakeholders within and across regions, while the water transfers may cause severe damage to sensitive ecological systems. Therefore, to arrive at realistic and fair resolutions, one must take into account not only the economics and politics of the situation but also the water quantity and quality changes that may occur within the altered hydrological system as well as the ecosystems contained therein. When the effects of climate change and the closely connected activities of energy production and usage are also considered, the complexity of the problem becomes even greater and messier. Accordingly, one must adopt an integrative and adaptive approach to water and environmental governance that specifically recognizes the conflicting value systems of stakeholders, including nature and future generations even though they are not present at the bargaining table. The 16 chapters in this leading-edge book are written by authors who presented their original research at the International Conference on Water Resources and Environment Research (ICWRER) 2013, which was held in Koblenz, Germany, from June 3rd to 7th, 2013, and subsequently submitted expanded versions of their research for review and publication in this timely book. The rich range of contributions are put into perspective in the first chapter and then categorized into four main interconnected parts: Part I: Management and EvaluationPart II: Global, Trans-boundary and International Dimensions Part III: Consensus-building, Bargaining and Negotiation Part IV: Ecological and Socio-economic Impacts

The latest cutting-edge research on flood pulsing and wetland restoration in North America

Presenting the latest research from leaders in the field of restoration ecology, Flood Pulsing in Wetlands reflects the current movement to incorporate flood pulsing into wetland restoration efforts. Emphasizing how integral flood pulsing is to successful wetland restoration, the book’s contributors provide descriptions of restoration projects across North America in which flood pulsing has been primarily used to restore beneficial hydrodynamic conditions to floodplain areas, and improve or save vegetation, wildlife, and terrain.

Detailing the importance and applicability of recreating flood-pulsed conditions on floodplains for successful restoration, the first chapter introduces the concept of flood pulse and its unique role in wetland restoration. The following chapters detail the strategies and results of individual projects and the impact flood pulsing had on the projects’ overall goals. Case studies detail the history of each region, such as the Southwest, including the Sonoran Desert communities and the Middle Rio Grande; the Missouri River in Montana; the Illinois River Valley; and the Southeast, including Brushy Lake, Arkansas. Also documented is the most famous case of flood pulsing used in the restoration of an entire landscape, the Kissimmee River project. Approaches used to restore specific plant and animal populations, the unique ecological concerns of each region, and the future outlook for each area are fully described.

Extensive bibliographies for each chapter make Flood Pulsing in Wetlands: Restoring the Natural Hydrological Balance the essential reference for restoration ecologists, consultants in wetland restoration, government and restoration agency employees, land managers, ecologists, foresters, and geologists.

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 book demonstrates the role of dominant ecological factors on the organisms of running water and the functioning of the ecosystem, as well as the consequences of human activity. It provides vision of certain rivers and streams that represent various types of European watercourses.

The large lakes of the East African Rift Valley are among the oldest on Earth, and are vital resources for the people of their basins. They are unique among the large lakes of the world in terms of their sensitivity to climatic change, rich and diverse populations of endemic species, circulation dynamics and water-column chemistry, and long, continuous records of past climatic change. A comprehensive study of the large African lakes is long overdue. The scientific justification for such an effort is noted in the previous paragraph and is illustrated in great detail in this volume. Societal need for the sustainable utilization of these lakes offers an even more compelling reason for examination of biological food webs, water quality, and past climate variability in East Africa. The lakes provide the most important source of protein for the people of the African Rift Valley, and fish populations are shifting dramatically in response to fishing pressure, introduction of exotic species, land use impact on water quality, and perhaps climatic change. Current estimates of primary productivity, the underpinning of the food resource, are extremely crude and based on only a few spot measurements.
