This book was released on 2024-03-01 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the development of societies and economies, the process of industrialization and urban modernization is accelerating, urban populations are increasing, and more and more wastewater is generated and released. Large quantities of hazardous industrial and agricultural wastewater and domestic sewage are discharged directly into reservoirs, lakes, rivers and the sea, without adequate treatment. The wide range of pollutants discharged can degrade, interact, and transform in aquatic environments. When light, temperature, nutrients and other natural conditions are suitable, it is common for algal species to burst into bloom, causing serious damage to the ecological environment of the receiving water body. As the flux of river discharge into the sea increases year by year, the deterioration of coastal water environments accelerates. Meanwhile, variations in climate and vegetation impact basin hydrological proceses and river runoff into the sea.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract : The objective of this dissertation is to develop a framework of coupling model system and apply the system (i.e., single or multiple model components) in the Great Lakes to better understand the impacts of multi-scale hydrodynamics of coastal systems. This work has included three main topics that reveal the lake dynamics from basin to nearshore scales. In the basin scale, a study of the long-term wave climate of Lake Michigan from 1979 to 2020 is conducted following the climate change over the past decades, and a high-resolution wave model is performed for hindcasting. The details of this study are included in chapter 3. Two nearshore related cases are studied in Lake Michigan and Lake Ontario, respectively. The occurrence of meteotsunamis is not uncommon in Lake Michigan, and it has significant contributions in a nearshore flooding event (i.e., meteotsunami-induced flooding). The modeling study of nearshore meteotsunami-induced flooding is produced in the Ludington, Michigan nearshore of Lake Michigan. The study applied an extremely high-resolution hydrodynamic model with localized configurations to adapt to specific features (i.e., breakwaters and wet/dry processes). Numerical experiments were examined to evaluate the recent flooding situation and additional flooding analysis was performed to represent near future climate scenarios. The study is expected to set up a framework in the future for similar work in different locations. The details can be found in chapter 4. Another phenomena related to nearshore processes is conducted on the northern shore of Lake Ontario near the town of Ajax. To resolve the transport issues (i.e., discharge plume and pollutant of concern footprint dimensions), a high-resolution, linked hydrodynamic-tracer model is applied. The model results are validated with observations and then used for qualifying the footprint dimensions. The results and suggestions for potential management aspects are given in chapter 5.

Available in PDF, EPUB and Kindle. Book excerpt: Scientists, regulators, and the general public are now more and more aware of the chemicals present in surface waters worldwide. Agrochemicals, such as herbicides or insecticides, pharmaceuticals and cosmetics can be detected at low to medium concentrations in seas, groundwaters and rivers. Among freshwaters, lakes are of particular concern. These large reservoirs are used as sources of food and drinking water, but also serve for recreational activities. This book aims in presenting insights into the physical, chemical, and ecological dynamics of large lakes that enable proposing recommendations for sustainable lake management regarding chemicals. Lake Geneva, Switzerland, is used as a case study, but the developed methodologies and tools can be useful for lake water quality management in general. A first chapter is dedicated to the chemicals entering the lake through agriculture. These are mainly pesticides. After a review of the different types of compounds, the authors present the main pathways these compounds follow to enter the lake. The case of glyphosate, an herbicide largely used worldwide, is presented. A second chapter illustrates the urban source of pollutants with the case of pharmaceuticals and biocides. Two models are presented that allow estimating the load and the dynamic of these chemicals that may exit from an urban catchment and therefore reach a lake. Special attention will be paid to the ‘end of pipe’ removal of these compounds at a WWTP. A third chapter is dedicated to the lake circulation. The aim of this chapter is to present an overall description of the lake’s hydrodynamics, which is driven by three factors: wind, temperature and Coriolis forces. To achieve this aim, a hydrodynamic model is presented that allows describing the behavior of the top layer of the lake based on the wind direction. The importance of stable hydrogen and oxygen isotopes for characterizing the sources of water and the mixing processes in the lake is also described. The next chapters are dedicated to a Bay, called the Vidy Bay, that receives the treated effluents of the largest wastewater treatment plant of the lake catchment. This latter represents therefore one of the major point sources of contaminants for lake Geneva. These two chapters will focus on the various processes that control the transfer of chemicals (associated to particles or in a dissolved state) discharged into the bay and transported to the lake’s main water body. Then, a next chapter focuses on one major issue of chemicals in aquatic systems like lakes, i.e. the risk of the mixture of chemicals. The evaluation of the risk of mixture is not trivial and the models that allow doing it are presented in a critical way. Their validity as predictive tools is illustrated with the example of herbicides mixture in Lake Geneva. A final chapter synthesizes the main findings and discusses some recommendations for the management of large lakes regarding micropollution.

This book was released on 2012-12-06 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the late 1970s. the adverse effects of man-made eutrophication became manifest in many countries. which explains. perhaps. why there was such a broad interest when the former Resources and Environment Area of the International Institute for Applied Systems Analysis (IIASA) organized a workshop on the subject. There was such an enthusiasm among the partici pants that two further workshops were quickly organized. one on deep and the other on shallow lake eutrophication problems. The organization of these meetings was extremely stimulating. and the round table discussions among scientists from both West and East remain thought provoking for those who took part. The general feeling emerged that the complexity and multifaceted nature of the problem, even though perhaps not fully recognized at that time. clearly demanded a systems analysis approach. No wonder. then. that the request made by the Hungarian Member Organization of nASA to adopt Lake Balaton as a "real life laboratory" for an nASA case study fell on fertile ground. the more so since it appeared that shallow lake eutrophication had received less attention and was less well understood than that of deep lakes. And so the nASA Lake Balaton Case Study began. with the appointment of Gerrit van Straten as the first leader of the project.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: models were employed to construct ensemble water and nutrient load predictions and in turn, improve the reliability of the load estimates. The contributions of external loads and internal processes to the water quality of a waterbody were quantified to understand the dynamic relationship between drivers and algal blooms processes in a waterbody. Comprehensive future climate projections were incorporated into the modeling to test whether the current management practices can be effective under projected climate change scenarios and investigate the impacts of climate change on water quantity and quality in the watershed lake system. This study is expected to provide information and tools that help develop spatially integrated climate adaptation plans for improved sustainability of a watershed lake system.

Available in PDF, EPUB and Kindle. Book excerpt: Lakes are highly essential for their water quality, habitat suitability, and water supply. Lakes constitute important source for aquatic life, fish, wildlife, and human, but can undergo rapid environmental changes. Most important factors that affect lake ecosystem are climate, atmospheric inputs, land use, morphology, and physiography. Several environmental problems can affect a lake's water quality, and habitat suitability. The book "Lake Sciences and Climate Change" deals with several aspects of lake sciences (botany, zoology, geology, chemistry, models, morphology, and physiography) ,as well as the effect of climatic changes on lake body ecosystem. The book is divided into three sections and structured into 10 chapters. The first section discusses the relationship between lake and climatic change; the second section explains lake biology and health; and the third section focuses on water quality, management, and modeling. Scientists from different fields of lake sciences reported in this book their findings.

This book was released on 1998-05-31 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: If present trends continue, most climatologists agree that the concentration of carbon dioxide in the atmosphere will have doubled by the year 2050. This increase in CO 2 will have a major effect on the global climate and substantially alter the physical, chemical and biological characteristics of lakes throughout the world. In recent years, it has become clear that year-to-year changes in the weather have a major effect on the seasonal dynamics of lakes. Many water quality problems that were once regarded as "local" phenomena are now known to be influenced by changes in the weather that operate on a regional or even global scale. For example, blooms of toxic blue-green algae can be induced by prolonged reductions in the intensity of wind-mixing as well as increased supplies of nutrients. Long-term studies in the English Lake District have shown that many of these variations are quasi-cyclical in nature and can be related to long-term changes in the distribution of atmospheric pressure over the Atlantic Ocean. It is not yet clear what effect these changes have on the dynamics of European lakes but much of the historical data required to extend these analyses to continental Europe is already available. In the early 1970s the International Biological Programme served as a particularly effective focus for comparative limnological research in eastern as well as western Europe.
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.

This book was released on 2008 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Technical Paper addresses the issue of freshwater. Sealevel rise is dealt with only insofar as it can lead to impacts on freshwater in coastal areas and beyond. Climate, freshwater, biophysical and socio-economic systems are interconnected in complex ways. Hence, a change in any one of these can induce a change in any other. Freshwater-related issues are critical in determining key regional and sectoral vulnerabilities. Therefore, the relationship between climate change and freshwater resources is of primary concern to human society and also has implications for all living species. -- page vii.
Download or read book Lake Water written by Oleg S. Pokrovsky and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Lake ecosystems are known to be valid sentinels for current climate changes and anthropogenic pressure because they provide indicators of these impacts either directly or indirectly through the influence of climate and human activity on their catchments. Among these indicators, to name just a few, are water temperature, dissolved organic carbon, nutrients and metals, phyto- and zooplankton composition as well as population and biodiversity of crustacea, mollusks and fish. The advantages of using lakes as tracers of climatic changes and anthropogenic impacts on aquatic ecosystems are multiple. Lake ecosystems are well constrained, confined and are studied in a sustained fashion; lakes respond directly to climate change and local and global pollution via incorporating the effects of these impacts occurring within the catchment; lakes integrate responses over time, and thus allow to avoid the random or unique single-time effects. Finally, lakes of various sizes are distributed worldwide and, as such, can act as sentinels across various climatic conditions while exhibiting different degrees of vulnerability to external pressure depending on their size and specific location capturing different aspects of climate change (e.g., changing precipitation regime, heat waves, permafrost thaw, invasion of new species, local and global (dispersed) pollution). However, the majority of published studies on lakes in the boreal and subarctic zone deal with Western and Northern Europe and Northern America, with quite limited information on lakes in the NW Russia. This book is intended to partially fill this gap by presenting 13 chapters describing the hydrology, hydrochemistry and hydrobiology of various lakes located in the NW European Russia, from the Finland border in the West to the Ural Mountains in the East. The thirteen chapters of the book, written by the experts in the field of biogeochemistry, limnology and zoology cover full limnetic ecosystems, from lake physical characteristics to lake water chemistry, microbiology, phytoplankton and zooplankton population, Crustacea, mollusks and fish. A multidisciplinary approach across wide geographical zones, comprising both small and large lakes of the Russian Subarctic, presented in this book, will be interesting for a large community of scholars, students, and researchers from academic and private organizations"--
