Available in PDF, EPUB and Kindle. Book excerpt: To fulfill its commitment to clean water, the United States depends on limnology, a multidisciplinary science that seeks to understand the behavior of freshwater bodies by integrating aspects of all basic sciencesâ€"from chemistry and fluid mechanics to botany, ichthyology, and microbiology. Now, prominent limnologists are concerned about this important field, citing the lack of adequate educational programs and other issues. Freshwater Ecosystems responds with recommendations for strengthening the field and ensuring the readiness of the next generation of practitioners. Highlighted with case studies, this book explores limnology's place in the university structure and the need for curriculum reform, with concrete suggestions for curricula and field research at the undergraduate, graduate, and postdoctoral levels. The volume examines the wide-ranging career opportunities for limnologists and recommends strategies for integrating limnology more fully into water resource decision management. Freshwater Ecosystems tells the story of limnology and its most prominent practitioners and examines the current strengths and weaknesses of the field. The committee discusses how limnology can contribute to appropriate policies for industrial waste, wetlands destruction, the release of greenhouse gases, extensive damming of rivers, the zebra mussel and other "invasions" of speciesâ€"the broad spectrum of problems that threaten the nation's freshwater supply. Freshwater Ecosystems provides the foundation for improving a field whose importance will continue to increase as human populations grow and place even greater demands on freshwater resources. This volume will be of value to administrators of university and government science programs, faculty and students in aquatic science, aquatic resource managers, and clean-water advocatesâ€"and it is readily accessible to the concerned individual.

This book was released on 1983 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes field investigations conducted at seven reservoirs in 1979 and 1980 to determine the effect of reservoir releases on tailwater biota. The study sites differ greatly in project purpose, depth of water release from the reservoir, and location and are representative of many U.S. Army Corps of Engineers reservoirs throughout the United States. Studies were conducted in tailwaters below both flood-control and peaking hydropower projects. Effects of reservoir discharge were most evident near the dams where environmental stress was most severe; farther downstream the effect were moderated. The invertebrate and fish communities in tailwaters were affected most by the temperature, volume, and timing of the discharges. High levels of iron and manganese occurred in most tailwaters, but their effects on invertebrates and fish were not addresed in this study. The numbers of invertebrate and fish species were largest in tailwaters of flood-control projects with warmwater release and smallest in tailwaters of large hydropower projects.

Download or read book Effects of Reservoirs Releases on Tailwater Ecology A Literature Review written by Charles H. Walburg and published by . This book was released on 1981 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document presents a review of the often contradictory literature describing the effects of release waters on the tailwater environment and biota. The physical and chemical conditions found in tailwaters downstream from warmwater and coldwater discharge impoundments are compared and contrasted to those found in natural streams. Reservoir discharges modify the physical, chemical, and biological characteristics of the stream ecosystem. Physical and chemical characteristics in tailwaters are primarily determined by the depth, volume, and schedule of water releases. The magnitude of change is related to the type of reservoir and to the design and operation of outlet structures. The structure of the biotic community reflects the physical and chemical conditions existing in a particular tailwater. The community is composed of organisms, including nonnative species, that are adapted to this environment. The effects of the tailwater environment on the life history, physiology, and abundance of selected species are described. This information will aid in the development of reservoir discharge guidelines that will enhance the quality of the tailwater environment to increase project benefits. (Author).
