With regional, national, and global processes affecting both the structure and function of lakes and rivers, assessment methodology must encompass many attributes to evaluate the impact of these processes on water quality. Many of the changes in biological communities correlate to resource exploitation, nonpoint pollutant interactions, and habitat alteration - factors that can be missed by routine chemical sampling. This creates the need for ecologically-based approaches to this problem. Biological monitoring is a fundamental part of an ecologically-based approach. Biological Monitoring of Aquatic Systems brings together contributions by authors recognized as leaders in the development and utilization of biological monitoring techniques for freshwater ecosystems. It provides a conceptual framework for the use of biological monitoring to assess the environmental health of freshwater resources. Biological monitoring is an important part of any water quality assessment program. Biological Monitoring of Aquatic Systems provides you with an understanding of water resources. It includes discussions concerning historical development, ecological basis, experimental design characteristics, case studies, and future concerns. As efforts to maintain and restore the world's water resources intensify, the need to develop accurate methods to assess the health of these resources becomes critical.

Simplistic thinking would have us believe that by eliminating the loading of a given pollutant, an aquatic system will revert to its previous pristine state. This premise is without scientific verification. Besides the fact that typically very little documentation exists defining what exactly that previous pristine state was, it should be noted that biological processes are non-linear. They reflect adaptations by populations and corresponding responses of trophic organization that are not predictable by linear models of recovery. Restoration of Aquatic Systems makes a clear delineation between genuine restoration and public perception of restoration efforts. Written by Robert Livingston, one of the foremost international authorities on ecosystem studies of freshwater, estuarine, and marine environments, this work is the final volume of a trilogy derived from 70 field-years of data garnered from 10 different coastal systems on the Atlantic and Gulf coasts. The text provides a synthetic look at the restoration of aquatic systems, emphasizing the functional basis that supports such activities, followed by a review of the evidence of recovery. Livingston considers numerous cases of scientific restoration; however, while the first two volumes could be considered pure science, this volume brings into play the impact of political as well as economic interests and where appropriate, media leverage. This work is thus concerned with just how effective the restoration process becomes as a product of a complex mixture of competing interests. From this effort, an interdisciplinary comparative database has been created that is currently being published in a series of books and peer-reviewed scientific journals. This work is used to evaluate system-level processes that determine the effects of nutrient loading and nutrient dynamics on phytoplankton/benthic macrophyte productivity and associated food web responses.

The 10th International Symposium on Process Systems Engineering, PSE'09, will be held in Salvador-Bahia, Brazil on August 16-20, 2009. The special focus of PSE 2009 is Sustainability, Energy and Engineering. PSE 2009 is the tenth in the triennial series of international symposia on process systems engineering initiated in 1982. The meeting is brings together the worldwide PSE community of researchers and practitioners who are involved in the creation and application of computing-based methodologies for planning, design, operation, control and maintenance of chemical and petrochemical process industries. PSE'09 will look at how the PSE methods and tools can support sustainable resource systems and emerging technologies in the areas of green engineering: environmentally conscious design of industrial processes. PSE methods and tools support: - sustainable resource systems - emerging technologies in the areas of green engineering - environmentally conscious design of industrial processes

Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressed--restoration--is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

The demand for high quality aquacultured products and an increasing concern for resource conservation has led individuals and large corporations to invest time and money in commercial scale recirculating production systems. However, there are relatively few reports of profitable recirculating production systems in operation. There is little doubt that most fish reared in ponds, floating net pens, or raceways can be produced in commercial scale recirculating systems. The objective of this book is to provide basic information and analytical skills for the reader so that they may make the proper design or investment decisions concerning water reuse and recycle systems. The chapters of this book are sequenced to provide continuity to a basic approach that would be used in designing a water reuse or recycle system. The chapter authors contributing to this book have written extensively in the literature already on the particular subject being addressed in their chapter. Considerable background information on the basic processes being presented is also given in each chapter to supplement the basic design information being provided. These chapters should provide the reader with essentially all the information required in order to design and manage a water reuse system. The book is written for engineers and biologists working in the area of intensive fish culture. The text should also prove useful as a design manual for practising aquaculturists and as a resource of current "state-of-the-art" methodologies associated with water reuse systems.

Chemical Kinetics and Process Dynamics in Aquatic Systems is devoted to chemical reactions and biogeochemical processes in aquatic systems. The book provides a thorough analysis of the principles, mathematics, and analytical tools used in chemical, microbial, and reactor kinetics. It also presents a comprehensive, up-to-date description of the kinetics of important chemical processes in aquatic environments. Aquatic photochemistry and correlation methods (e.g., LFERs and QSARs) to predict process rates are covered. Numerous examples are included, and each chapter has a detailed bibliography and problems sets. The book will be an excellent text/reference for professionals and students in such fields as aquatic chemistry, limnology, aqueous geochemistry, microbial ecology, marine science, environmental and water resources engineering, and geochemistry.

The new science of ecological engineering is winning increasing acceptance all over the world. Established industrial economies like Sweden and the United States are investing more in it as initial skepticism and regulatory hurdles are giving way to burgeoning investments by companies and municipalities, increased research activity, and great interest by the public. Less-developed countries are investigating inexpensive and effective ways to build their wastewater treatment infrastructure with ecological engineering. Eastern European countries and the former Soviet Union are turning to ecological engineering to solve their acute pollution problems. Ecological Engineering for Wastewater Treatment, Second Edition, presents comprehensive coverage of topics ranging from wastewater source separation at the household level to the use of huge, natural wetlands. It is an updated description of the state of the art, intended as a tool for teaching and inspiring the management of wastewater as a resource, one of the keys to sustainable development. In this Second Edition, existing chapters have been updated, new chapters have been added, and a comprehensive index has been added.
