A stunningly illustrated atlas of the world's rivers, estuaries, and deltas, and their ecosystemsFrom the Congo and the Mekong to the Seine and the Mississippi, Earth's rivers carve through landscapes before coursing into the world's oceans through estuaries and deltas. Their inexorable flow carries sediment and more, acting as lifeblood for a variety of ecosystems and communities. More than any other surface feature of Earth, rivers, estuaries, and deltas are vitally important to our economic and social well-being, and our management of them often sits at the sharp edge of today's most pressing environmental challenges. The World Atlas of Rivers, Estuaries, and Deltas takes readers on an unforgettable tour of these dynamic bodies of water, explaining how they function at each stage of their flow. Combining maps and graphics with informative essays and beautiful photos, this invaluable reference book will give you a new appreciation for the power that rivers, estuaries, and deltas wield. Features a wealth of color photos, maps, and infographicsBrings together invaluable perspectives from leading expertsDescribes the rich biodiversity associated with the world's rivers, estuaries, and deltasExplains how rivers, estuaries, and deltas work, from river networks to deltaic floodplains, and sheds light on the erosion, movement, and deposition of sedimentDescribes the anatomy of rivers, estuaries, and deltas, from channel geometry and river planforms to estuarine shape and delta morphologyExamines the ecology and ecosystems of rivers, estuaries, and deltas and how humans interact with these environmentsAdditional topics include damming, climate change, water use, pollution, resource management, and planetary health, as well as future perspectives on these vital landscapes

This fully revised and updated edition introduces the reader to sedimentology and stratigraphic principles, and provides tools for the interpretation of sediments and sedimentary rocks. The processes of formation, transport and deposition of sediment are considered and then applied to develop conceptual models for the full range of sedimentary environments, from deserts to deep seas and reefs to rivers. Different approaches to using stratigraphic principles to date and correlate strata are also considered, in order to provide a comprehensive introduction to all aspects of sedimentology and stratigraphy. The text and figures are designed to be accessible to anyone completely new to the subject, and all of the illustrative material is provided in an accompanying CD-ROM. High-resolution versions of these images can also be downloaded from the companion website for this book at: www.wiley.com/go/nicholssedimentology.

Lakes are among the most extensive freshwater aquatic ecosystems in the world. Their evolution results from the interactions of numerous natural and anthropogenic factors. This book includes 12 chapters and presents case studies on the impacts of changes and tectonic movements on the evolution of lake water levels (Section 1), the interactions between anthropogenic activities and the physicochemical characteristics of lakes (Section 2), and the limnological characteristics and their interactions with other components of the environment (Section 3).

The environmental history of "the most polluted lake in America."​​Native Americans have long regarded Onondaga Lake as one of the most sacred spaces in the continent, the place where peace between nations was achieved and the Haudenosaunee Confederacy was created. In the mid-twentieth century, however, it acquired a wholly different reputation as "the most polluted lake in America." Toxic Lake is an environmental history of this complex ecological system, tracking how it was tarnished, the costly efforts to clean it up, and the controversies those efforts generated. Thomas Shevory argues that the history of Onondaga Lake mirrors the larger environmental history of the US, from colonization to the industrial era, resulting, eventually, in the rise of social movements and legislative action for environmental protection. Layered within this history is the dismissal of indigenous land claims and the marginalization of indigenous voices in clean-up efforts. Toxic Lake illustrates that the failure to prevent the environmental destruction of Onondaga Lake was part of a political climate which favored unregulated industrial production and urban growth, ignoring the destructive impacts on local environments. Shevory argues this larger failure was the result of an active process of privileging the economic interests of polluters over other business interests, expanding neighborhoods, and indigenous rights. He concludes with an investigation of New York's recent declaration that the clean-up is complete, questioning what exactly that means and whether the lake's status as a sacred space will ever be re-established. Toxic Lake is a compelling work of history, demonstrating the disastrous effects of pollution and the importance of community involvement in environmental activism.

River deltas are among the most sensitive and widely exploited territories habitats on Earth. Although predominantly shallow aquatic environments, river deltas are extremely important environments socioeconomically and their usage places ever-increasing stresses on these habitats, especially where there is any anthropogenic involvement. The effective governance and administration of river delta regions often requires an intricate scientific understanding of the various contributary natural processes. River Deltas Research - Recent Advances is a book that draws on the most recent world-class scientific research on river delta topics including climate change, water quality, geomorphology, anthropogenic stresses, water quality, sedimentation, ecosystems, and many more. The research was carried out by researchers who specialise in the river deltas and related issues.

In Casting Iconic Waters, writer, naturalist, and educator Steve Ramirez takes the reader on a physical and philosophical journey to some of the most legendary rivers and wild landscapes in America.

Handbook of Water Pollution discusses a wide range of contaminants heavily affecting our environment and water bodies. The chapters discuss heavy metals, metalloids, pesticides, explosives, toxic chemicals, dyes, plastics, e-wastes, fertilizers, detergents, nitrates/nitrites, phosphates, hydrocarbons, and fecal wastes, along with their sources of action against our environment, their methods of analysis, and finally, their treatments are all presented in detail. Our environment is heavily affected due to extreme human activities. Environmental pollution is a major concern worldwide. Within this, water pollution is one of the major challenges that puts the total ecology at risk. Water pollution is alarming everywhere; many governing authorities believe it is also an unavoidable result of human activity. However, the economic cost of water pollution far outweighs the benefits of skimping on its cause. Water pollution is not just merely related to financial cost but related to all living beings. Toxic waste is getting into the water bodies in various regions, causing many illnesses in humans and poisoning other living things. The destruction of any single component of our ecosystem can have a devastating effect on our biodiversity. Therefore, it is necessary to understand the causes of pollution, their nature and mechanism, and, at the same time, study the remedies. The major causes of water pollution are industrial waste, sewage, plastics, oil leakage, biological organisms, toxic chemicals and radioactive waste, and so on. A tremendous amount of research work is going on around the world to understand the causes, their mechanism, and solutions. Many new works are published every day, therefore it's important to gather some of the most relevant findings in one place. This will serve as a link between collected knowledge and current advancements, while also facilitating future thinking.

Die Erforschung der Gewassernamen bekam nach 1945 durch die Tatigkeit des Indogermanisten Hans Krahe neue Impulse, die zur systematischen Erfassung der deutschen Gewassernamen im Projekt Hydronymia Germaniae"e; (1960-2005) fuhrten und eine rege Forschungstatigkeit auslosten. Die sich hierdurch ergebenden Erkenntnisse uber das hohe Alter vieler Gewassernamen in Mitteleuropa, ihren besonderen kulturgeschichtlichen Wert, ihren sprachlichen Bau und ihre Etymologie waren bislang nur in rein wissenschaftlichen Publikationen zuganglich. Das Deutsche Gewassernamenbuch verfolgt das Ziel, einem breiten, nicht fachkundig ausgebildeten Interessentenkreis die Forschungsergebnisse jetzt in der Form eines etymologischen Namenbuchs zu erschlieen. In einer Einleitung werden die Leser uber die Moglichkeiten, deutsche Gewassernamen im Verlauf der Geschichte zu bilden, uber die Benennungsmotive und historische Schichtung (keltische, germanisch-deutsche, slawische Namen) informiert. Die Namenartikel, die entweder dem Namen eines Gewassers (z. B. Donau) oder dem Namen mehrerer Gewasser (z.B. Traun) auf der Grundlage einer Belegreihe erklaren, folgen einem einheitlichen Aufbau: Namen-Stichwort, Lokalisierung, Belege, Deutung, Literatur.

During the first two decades of the twenty-first century, the whole messy truth about the legacy of last century's big dam building binge has come to light. What started out as an arguably good government project has drifted oceans away from that original virtuous intent. Governments plugged the nation's rivers in a misguided attempt to turn them into revenue streams. Water control projects' main legacy will be one of needless ecological destruction, fostering a host of unnecessary injustices.

Doctoral Thesis / Dissertation from the year 2015 in the subject Environmental Sciences, grade: A, , language: English, abstract: This study explains that Majalgaon Reservoir is in rich biodiversity of zooplankton, fishes and need to conservation in the future. The investigation generated some important baseline data on the pollution status Zooplankton and fish community structure of the reservoir. These data would be helpful in planning for future policy decisions on using the reservoir for the better conservation and management of the precious wildlife in the world-famous sanctuary. Analysis and interpretation of the data on diversity of biota and water quality parameters provided the necessary information to assess the impact of local people, researcher, and scientist related activities on the limnology of the reservoir.In any aquatic ecosystem limnological characteristic can affect both fauna and flora. Biodiversity contributes both directly and indirectly to human such as food for good health, security, social relationship, life and freedom for choice etc. In last decade people interfere with ecosystem and over exploitation of natural resources its result that biodiversity decreases. But thelosses in biodiversity and change in ecosystem service have adversely affected the well-being. The present study is relevant to limnological study, biodiversity of zooplankton and fishes (species) in Majalgaon Reservoir. Recommendations Made by the author:1. Conservation and ecofriendly utilization of biotic potential like fishery.2. Creation of awareness in the mind of people related to the water body about importanceand survival of the water body through seminars, field study visiting etc.3. The Majalgaon reservoir is highly potential and can yield substantial quantity of fishproduction of advanced scientific fish culture technology is implemented and by avoidingexcessive fishing throughout the year.4. To establish fish breeding center, which will helpful for fish culture and its production itwill also helpful to solve the same unemployment.5. To establish ornithological center. 6. It is also recommended that the Majalgaon water reservoir is not only the source of waterfor population but it is important source of fishery and it is an important aquaticecosystem.7. Hence, the combined intensive effect of hydrobiologists, taxonomists, biotechnologists can behelpful for the survival and effective utilization of precious water body.

Interdisciplinary and practice-oriented overview of sediment management in river basins Sustainable Sediment Management in Regulated Rivers shows how sediment management can be incorporated into engineering plans at an early stage. The expert authors base their approach on the geomorphology and hydroecology of the whole river system. Their insight provides readers with a balanced perspective to the economics of riverbed engineering and other interventions into natural river systems. Importantly, the work also outlines the process of devising effective sediment management plans. To illustrate best practices, numerous case studies for sediment processes and for the sustainable management of river systems in the USA and elsewhere have been included. Key topics covered in the work include: Changes in sediment supply Upstream sediment supply management Sediment removal Sediment management and environmental consequences downstream of dams Managing sediment through multiple reservoirs Engineers, consultants, and industry professionals in both the private and public sectors will benefit from the information in Sustainable Sediment Management in Regulated Rivers to make better and more informed decisions in the planning and execution of river basin engineering projects.
