This book was released on 2013-10-22 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: Principles and Methods for Determining Ecological Criteria on Hydrobiocenoses is a collection of papers presented at the 1975 European Scientific Colloquium on Principles and Methods for Determining Ecological Criteria on Hydrobiocenoses, held in Luxembourg. This Colloquium aims to define a scientific basis for assessing the results of pollution on aquatic fauna and flora, as well as the biological methods to be used in assessing the extent of such pollution. This book is organized into four parts encompassing 29 chapters. After a brief overview of a series of parameters for the specific uses of different water classifications and regional evaluation of water pollution, this book goes on examining the ecological consequences of water pollution establishment of criteria and the ecological variable and their effect on aquatic fauna. These topics are followed by a discussion of the value of aquatic plants in water quality characterization, as well as the principles of the methods used. The succeeding parts highlight the concepts and practical methods used in the biological monitoring of surface waters. These parts particularly consider the benefits of using bioindicators and laboratory bioassays. The concluding discusses a comparative study of biological-ecological water assessment methods of water quality. This book will be of value to environmental scientists, engineers, and researchers.

Download or read book Water Quality Indices written by Tabassum Abbasi and published by Elsevier. This book was released on 2012-03-10 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers water quality indices (WQI) in depth – it describes what purpose they serve, how they are generated, what are their strengths and weaknesses, and how to make the best use of them. It is a concise and unique guide to WQIs for chemists, chemical/environmental engineers and government officials. Whereas it is easy to express the quantity of water, it is very difficult to express its quality because a large number of variables determine the water quality. WQIs seek to resolve the difficulty by translating a set of a large number of variables to a one-digit or a two-digit numeral. They are essential in communicating the status of different water resources in terms of water quality and the impact of various factors on it to policy makers, service personnel, and the lay public. Further they are exceedingly useful in the monitoring and management of water quality. With the importance of water and water quality increasing exponentially, the importance of this topic is also set to increase enormously because only with the use of indices is it possible to assess, express, communicate, and monitor the overall quality of any water source. Provides a concise guide to WQIs: their purpose and generation Compares existing methods and WQIs and outlines strengths and weaknesses Makes recommendations on how the indices should be used and under what circumstances they apply

Download or read book Assessing the Ecological Integrity of Running Waters written by M. Jungwirth and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 491 pages. Available in PDF, EPUB and Kindle. Book excerpt: The assessment of the ecological integrity of running waters is a prerequisite to an understanding of the effects of human alterations. The evaluation of degradation processes provides key information on how to avoid further negative impacts. The success of future conservation, mitigation and restoration activities will rely on sound assessment methodologies and their ecological relevance and applicability. Assessment methodologies are therefore an integral part of sustainable river management. This book synthesizes and discusses state-of-the-art experiences in assessment methodologies. Including the latest knowledge on structures, processes and functions of running waters as a fundamental basis for developing adequate assessment methods, the book focuses on method development, application, and in particular on integrated assessment methods. This book is directed at scientists and managers with the aim of more effective preservation, restoration and maintenance of the ecological integrity of running water ecosystems.

Download or read book Riverine Ecosystem Management written by Stefan Schmutz and published by Springer. This book was released on 2018-05-08 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book surveys the frontier of scientific river research and provides examples to guide management towards a sustainable future of riverine ecosystems. Principal structures and functions of the biogeosphere of rivers are explained; key threats are identified, and effective solutions for restoration and mitigation are provided. Rivers are among the most threatened ecosystems of the world. They increasingly suffer from pollution, water abstraction, river channelisation and damming. Fundamental knowledge of ecosystem structure and function is necessary to understand how human acitivities interfere with natural processes and which interventions are feasible to rectify this. Modern water legislation strives for sustainable water resource management and protection of important habitats and species. However, decision makers would benefit from more profound understanding of ecosystem degradation processes and of innovative methodologies and tools for efficient mitigation and restoration. The book provides best-practice examples of sustainable river management from on-site studies, European-wide analyses and case studies from other parts of the world. This book will be of interest to researchers in the field of aquatic ecology, river system functioning, conservation and restoration, to postgraduate students, to institutions involved in water management, and to water related industries.

Download or read book Bioassessment of Freshwater Ecosystems written by Robert C. Bailey and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquatic ecosystem assessment is a rapidly developing field, and one of the newer approaches to assessing the condition of rivers and lakes is the Reference Condition Approach. This is a significant advancement in biomonitoring because it solves the problem of trying to locate nearby control or reference sites when studying an ecosystem that may be degraded, a problem that bedevils traditional approaches. Rather than using upstream reference sites in a river system or next-bay-over reference sites in a lake, an array of ecologically similar, least-exposed to stress sites scattered throughout a catchment or region is used. Once the reference condition has been established, any site suspected of being impacted can be assessed by comparison to the reference sites, and its status determined. The Reference Condition database, once formed, can be used repeatedly.

Download or read book Aquatic Biodiversity II written by H. Segers and published by Springer Science & Business Media. This book was released on 2006-01-20 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Freshwater Biodiversity is a much underestimated component of global biodiversity, both in its diversity and in its potential to act as models for fundamental research in evolutionary biology and ecosystem studies. Freshwater organisms also reflect quality of water bodies and can thus be used to monitor changes in ecosystem health. The present book comprises a unique collection of primary research papers spanning a wide range of topics in aquatic biodiversity studies, and including a first global assessment of specific diversity of freshwater animals. The book also presents a section on the interaction between scientists and science policy managers. A target opinion paper lists priorities in aquatic biodiversity research for the next decade and several reactions from distinguished scientists discuss the relevance of these items from different points of view: fundamental ecology, taxonomy and systematics, needs of developing countries, present-day biodiversity policy at European and at global scales. It is believed that such a platform for the interaction between science and science policy is an absolute necessity for the efficient use of research budgets in the future.
