Lake Ladoga is the largest lake in Europe and, with its surface of 17,891 km2 and volume of 837 km3, it ranks among the top fifteen of the world's freshwater bodies. The ecological condition of Lake Ladoga is of concern to several million people living in its surroundings. There is evidence of water quality degradation and gradual eutrophication of the lake during the past decades; on the other hand, pollution control measures have improved the situation in many of the most polluted sites near industrial effluent sources. The first international Lake Ladoga Symposium was held in St. Petersburg on 22-26 November, 1993. The symposium was attended by 160 scientists, and about half of the papers presented at the symposium have been edited for this book. The contributions are grouped under the following headings: Present state of Lake Ladoga; Hydrodynamics of Lake Ladoga and other large water bodies; Water quality and pollution; Ecological studies of Lake Ladoga biota; History of Lake Ladoga and rates of change in its environment; Research methods for large lakes. Besides providing up-to-date information on the state of the lake, the papers deal with studies of many other large lakes of the cold-temperature zone and the general problems and methods of large lake research. Furthermore, the book is a valuable source of reference to the voluminous Russian limnological literature.
This is the first book to be entirely devoted to the geomorphology and sedimentology of estuaries. The chapters in the book are structured according to the morphogenetic classification which is based on a new definition of estuaries and covers all areas within this field. The material is presented in such a way that it serves both as a reference for the researcher and as a textbook for use on courses covering estuaries, coastal environments, sedimentology and oceanography. Internationally renowned specialists have provided in-depth descriptions of the geomorphology, sedimentology and interactive processes associated with each particular subject.
Understanding and being able to predict fluvial processes is one of the biggest challenges for hydraulics and environmental engineers, hydrologists and other scientists interested in preserving and restoring the diverse functions of rivers. The interactions among flow, turbulence, vegetation, macroinvertebrates and other organisms, as well as the transport and retention of particulate matter, have important consequences on the ecological health of rivers. Managing rivers in an ecologically friendly way is a major component of sustainable engineering design, maintenance and restoration of ecological habitats. To address these challenges, a major focus of River Flow 2016 was to highlight the latest advances in experimental, computational and theoretical approaches that can be used to deepen our understanding and capacity to predict flow and the associated fluid-driven ecological processes, anthropogenic influences, sediment transport and morphodynamic processes. River Flow 2016 was organized under the auspices of the Committee for Fluvial Hydraulics of the International Association for Hydro-Environment Engineering and Research (IAHR). Since its first edition in 2002, the River Flow conference series has become the main international event focusing on river hydrodynamics, sediment transport, river engineering and restoration. Some of the highlights of the 8th International Conference on Fluvial Hydraulics were to focus on inter-disciplinary research involving, among others, ecological and biological aspects relevant to river flows and processes and to emphasize broader themes dealing with river sustainability. River Flow 2016 (extended abstract book 854 pages + full paper CD-ROM 2436 pages) contains the contributions presented during the regular sessions covering the main conference themes and the special sessions focusing on specific hot topics of river flow research, and will be of interest to academics interested in hydraulics, hydrology and environmental engineering.

An incisive critique of Canada’s drinking water gatekeepers. Canada is celebrated for its abundance of fresh water, and few Canadians question the safety of the water that comes from our taps. But is this trust justified? One study estimates that contamination of drinking water causes 90,000 cases of illness and ninety deaths every year. In this authoritative review of decades of legislation, research, and independent regulatory critiques, accompanied by riveting stories of the many failures of our water supply, award-winning journalist Chris Wood and Canadian water policy expert Ralph Pentland expose how governments at every level have failed to protect our drinking water. The authors review the history of water management in Canada and approaches to the problem in Europe and the United States, then analyze our own approach in recent times, and finally propose a strategy to protect our water—including a new charter that will hold our government to account.
Pat McKeague’s eighth edition of INTERMEDIATE ALGEBRA is the traditional text for the modern student. Retaining the clarity and patience in explanation and concept development that has made it the book of choice for so many over the years, this new edition is replete with new examples, applications, and fresh new technology options. Throughout this text, you’ll find hundreds of new and relevant applications, with timely references to topics like gas prices and to companies like Google and Yahoo. Real data is used throughout, and wherever possible, has been updated to reflect recent changes. By showing how mathematics is used every day, the author makes students feel more at ease with the topics at hand. In a course where many students are entering with math anxiety, McKeague almost immediately calms students with chapter and section introductions, provides just in time study tips, and then helps students prepare with Getting Ready for Class boxes found throughout the text. This new edition comes complete with Enhanced WebAssign (EWA), the easy to use homework management system. With EWA, you can assign, collect, grade, and record homework assignments via the web. This complete learning system for students includes text-specific exercises, as well as tutorials, videos, and links to online tutoring, and eBook sections of the text. Important Notice: Media content referenced within the product description or the product text may not be available in the ebook version.

In Physical Processes in Estuaries the present day knowledge of the physics of transport phenomena in estuaries and their mathematical treatment is summarized: It is divided into following parts: - Water movements in estuaries - Estuarine fronts and river plumes - Internal waves and interface stability - Fine sediment transport, aggregation of particles, settling velocity of mud flocs - Sedimentation and erosion of fine sediments. For each topic an up-to-date review and recommendations for future research are given, followed by results of original studies. Since estuarine environments are the first to be threatened by urbanization and industrial exploitation this book is an important tool for students and researchers of environmental problems as well as for consultants and water authorities.
