Download or read book Water Temperature Characteristics of Lakes Subjected to Climate Change written by Midhat Hondzo and published by . This book was released on 1992 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: A deterministic, one dimensional, unsteady lake water temperature model was modified and validated to simulate the seasonal (spring to fall) temperature statification structure over a wide range of lake morphometries, trophic and meteorological conditions. Model coefficients related to hypolimnetic eddy diffusivity, light attenuation, wind sheltering, ad convective heat transfer were generalized using theoretical and empirical extensions. Propagation of uncertainty in the lake temperature model was studied using a vector state-space method. The output uncertainty was defined as the result of deviations of meteorological variables from their mean values. Surface water temperatures were affected by uncertain meteorological forcing. Air temperture and dew point temperature fluctuations had significant effects on lake temperature uncertainty. The method presents a useful alternative for studying long-term averages and variability of the water temperature structure in lakes due to variable meteorological forcing. The lake water temperature model was linked to a daily meteorological data base to simulate daily water temperature in several specific lakes as well as 27 lake classes characteristic for the north central US. Case studies of lake water temperature and stratification response to variable climate were made in a particulary warm year (1988) and a more normal one (1971). A regional analysis was conducted for 27 lake classes over a period of twenty-five years (1955-1979). Output from a global climate model (GISS) was used to modify te meteorological data base to account for a doubling of atmospheric CO2. The simulations predict that after climate change: 1) epilimnetic water temperatures will be higher but will increase less than air temperature, 2) hypolimnetic temperatures in seasonally stratified dimictic lakes will be largely unchanged and in some cases lower than at present, 3) evaporative water loss will be increased by as much as 300 mm for the open water season, 4) onset of stratification will occur earlier and overturn will occur later in the season, and 5) overall lake stability will become greater in spring and sumer.
Download or read book The Impact of Climate Change on European Lakes written by Glen George and published by Springer Science & Business Media. This book was released on 2009-11-27 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, scientists from eleven countries summarize the results of an EU project (CLIME) that explored the effects of observed and projected changes in the climate on the dynamics of lakes in Northern, Western and Central Europe. Historical measurements from eighteen sites were used to compare the seasonal dynamics of the lakes and to assess their sensitivity to local, regional and global-scale changes in the weather. Simulations using a common set of water quality models, perturbed by six climate-change scenarios, were then used to assess the uncertainties associated with the projected changes in the climate. The book includes chapters on the phenology and modelling of lake ice, the supply and recycling of nitrogen and phosphorus, the flux of dissolved organic carbon and the growth and the seasonal succession of phytoplankton. There are also chapters on the coherent responses of lakes to changes in the circulation of the atmosphere, the development of a web-based Decision Support System and the implications of climate change for the Water Framework Directive.

Download or read book Ecology of Meromictic Lakes written by Ramesh D. Gulati and published by Springer. This book was released on 2017-02-22 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents recent advances in the research on meromictic lakes and a state-of-the art overview of this area. After an introduction to the terminology and geographic distribution of meromictic lakes, three concise chapters describe their physical, chemical and biological features. The following eight chapters present case studies of more than a dozen meromictic lakes, showing the variety of physical and biochemical processes that promote meromixis. The result is a broad picture of the ecology and biochemistry of meromictic lakes in tropical and cold regions, in man-made pit lakes and euxinic marine lakes, and in freshwater as well as hypersaline lakes. In the final chapter the editors provide a synthesis of the topic and conclude that the study of meromictic lakes also offers new insights into the limnology of inland lakes. The book appeals to researchers in the fields of ecology, limnology, environmental physics and biophysics.

This is an ideal book for the scientific research community, but is also accessible to Masters and senior undergraduate students.
Download or read book Transport and Fate of Chemicals in the Environment written by John S. Gulliver and published by Springer Science & Business Media. This book was released on 2012-12-12 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: What happens when a chemical is released into the environment? It diffuses, disperses, adsorbs, reacts, and/or changes state. To predict and analyze this process, the mathematics of diffusion is applied to lakes, rivers, groundwater, the atmosphere, the oceans, and transport between these media. A sustainable world requires a deep understanding of the transport of chemicals through the environment and how to address and harness this process. This volume presents a succinct and in-depth introduction to this critical topic. Featuring authoritative, peer-reviewed articles from the Encyclopedia of Sustainability Science and Technology, Transport and Fate of Chemicals in the Environment represents an essential one-stop reference for an audience of researchers, undergraduate and graduate students, and industry professionals.

Download or read book Freshwater Ecosystems written by Committee on Inland Aquatic Ecosystems and published by National Academies Press. This book was released on 1996-10-11 with total page 400 pages. 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 sciences--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 species-- 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 advocates--and it is readily accessible to the concerned individual.
