This book was released on 2009-03-03 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: In many areas nutrient loadings to aquatic ecosystems have increased considerably as a result of population growth, industrial development and urbanisation. This has resulted in enhanced growth of phytoplankton, shifts in composition of the plankton community and changes in the structure of ecosystems, which are often considered to be objectionable. To help understanding these processes and to predict future conditions, a mathematical model, BLOOM, has been developed and applied since 1977. It simulates the biomass and composition of phytoplankton and macro algae in relation to the amount of nutrients, the under water light climate and grazing. It can be applied as a relatively simple screening tool, but also as part of advanced integrated modelling systems including additional hydrodynamic, suspended matter and habitat components. The model has been extensively validated, which means that its credibility was demonstrated systematically for certain types of applications. It has been applied as a supporting management tool to a very large number of aquatic systems worldwide: lakes, channel systems, estuaries, lagoons and coastal seas, using generic coefficients (one set for fresh water, one set for marine simulations) as much as possible. The principles of the model, its validation and a number of representative applications are described in Eco-Hydrodynamic Modelling of Primary Production in Coastal Waters and Lakes Using BLOOM.

Available in PDF, EPUB and Kindle. Book excerpt: Focusing on fundamental principles, Hydro-Environmental Analysis: Freshwater Environments presents in-depth information about freshwater environments and how they are influenced by regulation. It provides a holistic approach, exploring the factors that impact water quality and quantity, and the regulations, policy and management methods that are necessary to maintain this vital resource. It offers a historical viewpoint as well as an overview and foundation of the physical, chemical, and biological characteristics affecting the management of freshwater environments. The book concentrates on broad and general concepts, providing an interdisciplinary foundation. The author covers the methods of measurement and classification; chemical, physical, and biological characteristics; indicators of ecological health; and management and restoration. He also considers common indicators of environmental health; characteristics and operations of regulatory control structures; applicable laws and regulations; and restoration methods. The text delves into rivers and streams in the first half and lakes and reservoirs in the second half. Each section centers on the characteristics of those systems and methods of classification, and then moves on to discuss the physical, chemical, and biological characteristics of each. In the section on lakes and reservoirs, it examines the characteristics and operations of regulatory structures, and presents the methods commonly used to assess the environmental health or integrity of these water bodies. It also introduces considerations for restoration, and presents two unique aquatic environments: wetlands and reservoir tailwaters. Written from an engineering perspective, the book is an ideal introduction to the aquatic and limnological sciences for students of environmental science, as well as students of environmental engineering. It also serves as a reference for engineers and scientists involved in the management, regulation, or restoration of freshwater environments.
Download or read book Ecosystem Based Management Ecosystem Services and Aquatic Biodiversity written by Timothy G. O’Higgins and published by Springer Nature. This book was released on 2020 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquatic ecosystems are rich in biodiversity and home to a diverse array of species and habitats, providing a wide variety of benefits to human beings. Many of these valuable ecosystems are at risk of being irreversibly damaged by human activities and pressures, including pollution, contamination, invasive species, overfishing and climate change. Such pressures threaten the sustainability of these ecosystems, their provision of ecosystem services and ultimately human well-being. Ecosystem-based management (EBM) is now widely considered the most promising paradigm for balancing sustainable development and biodiversity protection, and various international strategies and conventions have championed the EBM cause and the inclusion of ecosystem services in decision-making. This open access book introduces the essential concepts and principles required to implement ecosystem-based management, detailing tools and techniques, and describing the application of these concepts and tools to a broad range of aquatic ecosystems, from the shores of Lough Erne in Northern Ireland to the estuaries of the US Pacific Northwest and the tropical Mekong Delta.
Download or read book Application of Hydrodynamic Cavitation in Environmental Engineering written by Janusz Ozonek and published by CRC Press. This book was released on 2012-03-06 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Containing the state-of-the-art in hydrodynamic cavitation, the book consists of two parts. The first part presents the physical basis of cavitation and a systematic classification of various kinds of cavitation and their formation sources. Special attention is paid to a group of factors that promote cavitation formation in natural liquids. A general model of cavitation is formulated as well as a sub-model describing dynamics of the formation, development and collapse of cavitation bubbles. The sub-model also includes effects of cavitation bubble occurrence on the liquid in the direct vicinity of bubbles. Finally, part one also includes a thermodynamic hydrocavitation model of water containing cavitation nuclei (natural waters). The second part deals with the application of hydrodynamic cavitation effects to advanced oxidation of substances that pollute the natural environment. Results of laboratory experiments on the application of cavitation effects to decompose selected organic compounds which hardly undergo biodegradation are presented, as well as a concept of the cavitation phenomenon application on an industrial scale. Application of Hydrodynamic Cavitation in Environmental Engineering will be useful to professionals dealing with the design and practical application of hydrocavitation reactors, and to academics in environmental engineering.
Download or read book Environmental Hydraulics written by V.P. Singh and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: Triggerd primarily byill effects of polluted air, soil and water resources on living species, public concern for environmental quality has been growing during the past four decades or so. One manifestation of this concern is found in occurrence of public debates as well as in the demand for full environmental impact assessment before a water-resources project is approved. Engineering soundness and economic feasibility are no longer sufficient criteria for construction of hydraulic works. As a result, environmental considerations have become very much a part of hydraulic analyses. In response to growing environmental concerns, the field of hydraulics has expanded and a new branch, called Environmental Hydraulics, has emerged. The focus of this branch is on hydraulic analyses of those environmental issues that are important for protection, restoration, and managementof environmental quality. The motivation for this book grew out of the desire to provide a hydraulic discussion of some of the key environmental issues.It is hoped that the book would serve to stimulate others to write more comprehensive texts on this subject of growing importance.
Download or read book Handbook of Environmental Fluid Dynamics Volume One written by Harindra Joseph Fernando and published by CRC Press. This book was released on 2012-12-12 with total page 638 pages. Available in PDF, EPUB and Kindle. Book excerpt: With major implications for applied physics, engineering, and the natural and social sciences, the rapidly growing area of environmental fluid dynamics focuses on the interactions of human activities, environment, and fluid motion. A landmark for the field, the two-volume Handbook of Environmental Fluid Dynamics presents the basic principles, fundamental flow processes, modeling techniques, and measurement methods used in the study of environmental motions. It also offers critical discussions of environmental sustainability related to engineering. The handbook features 81 chapters written by 135 renowned researchers from around the world. Covering environmental, policy, biological, and chemical aspects, it tackles important cross-disciplinary topics such as sustainability, ecology, pollution, micrometeorology, and limnology. Volume One: Overview and Fundamentals provides a comprehensive overview of the basic principles. It starts with general topics that emphasize the relevance of environmental fluid dynamics research in society, public policy, infrastructure, quality of life, security, and the law. It then discusses established and emerging focus areas. The volume also examines the sub-mesoscale flow processes and phenomena that form the building blocks of environmental motions, with emphasis on turbulent motions and their role in heat, momentum, and species transport. As communities face existential challenges posed by climate change, rapid urbanization, and scarcity of water and energy, the study of environmental fluid dynamics becomes increasingly relevant. This volume is a valuable resource for students, researchers, and policymakers working to better understand the fundamentals of environmental motions and how they affect and are influenced by anthropogenic activities.

Available in PDF, EPUB and Kindle. Book excerpt: Over the last two decades environmental hydraulics as an academic discipline has expanded considerably, caused by growing concerns over water environmental issues associated with pollution and water balance problems on regional and global scale. These issues require a thorough understanding of processes related to environmental flows and transport phenomena, and the development of new approaches for practical solutions. Environmental Hydraulics includes about 200 contributions from 35 countries presented at the 6th International Symposium on Environmental Hydraulics (Athens, Greece, 23-25 June 2010). They cover the state-of-the-art on a broad range of topics, including: fundamentals aspects of environmental fluid mechanics; environmental hydraulics problems of inland, coastal and ground waters; interfacial processes; computational, experimental and field measurement techniques; ecological aspects, and effects of global climate change. Environmental Hydraulics will be of interest to researchers, civil/environmental engineers, and professional engineers dealing with the design and operation of environmental hydraulic works such as wastewater treatment and disposal, river and marine constructions, and to academics and graduate students in related fields.
Download or read book Global Ecological Consequences of the 1982 83 El Ni o Southern Oscillation written by P.W. Glynn and published by Elsevier. This book was released on 1990-09-06 with total page 587 pages. Available in PDF, EPUB and Kindle. Book excerpt: El Niño is a meteorologic/oceanographic phenomenon that occurs sporadically (every few years) at low latitudes. It is felt particularly strongly in the eastern Pacific region, notably from the equator southwards along the coasts of Ecuador and Peru. The El Niño is a component of the ENSO (El Niño Southern Oscillation) which accentuates the intimate and causal connection between atmospheric and marine processes. Obvious manifestations of El Niño in the eastern Pacific are anomalous warming of the sea; reduced upwelling; a marked decline in fisheries, and high rainfall with frequent flooding. The 1982/83 El Niño was exceptionally severe, and was probably the strongest warming of the equatorial Pacific Ocean to occur during this century. The warming was intense and spread over large parts of the Pacific Ocean and penetrated to greater depths than usual. Many eastern Pacific coral reefs that had exhibited uninterrupted growth for several hundred years until 1983 were devasted by the disturbance and are now in an erosional mode. Marine species were adversely affected. The consequent depletion of the plant food base resulted in significant reductions in stocks of fish, squid etc. This led to a mass migration and near-total reproductive failure of marine birds at Christmas Island. Emphasis in this volume is placed on disturbances to benthic communities; littoral populations; terrestrial communities and extratropical regions.
