This book was released on 1986 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experiments to study the melting of a horizontal ice sheet with a flow of water above it were conducted in a 35 m long refrigerated flume with a cross section of 1.2x1.2 m. Water depth, temperature, and velocity were varied as well as the temperature and initial surface profile of the ice sheet. The heat transfer regimes were found to consist of forced turbulent flow at high Reynolds numbers with a transition to free convection heat transfer. There was no convincing evidence of a forced laminar regime. The data were correlated for each of the regimes, with the Reynolds number, Re, or the Grashof number combined with the Reynolds number as Gr/Re to the 2.5 power used to characterize the different kinds of heat transfer. For water flowing over a horizontal ice sheet, the melting heat flux, for low flow velocities, was not found to drop below the value for the free convection case-488.5 W/sq m-as long as the water temperature exceeds 3.4 C. This is significant since the free convection melt values far exceed those for laminar forced convection. At the low flow velocities, the melting flux was not dependent upon the fluid temperature until the water temperature dropped below 3.4 C, when q sub c = 135.7 (Delta T). In general, the heat transfer was found to significantly exceed that of non-melting systems for the same regimes. This was attributed to increased free stream turbulence, thermal instability due to the density maximum of water near 4 C, and the turbulent eddies associated with the generation of a wavy ice surface during the melting.

Download or read book The First International Lake Ladoga Symposium written by Heikki Simola and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 book was released on 2006-08-31 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first book on the subject, this monograph examines the phenomenon of a huge sealed, freshwater lake, isolated from the rest of the world by kilometers' thick ice. The existence of melting ice at the bottom of the huge Vostok Lake has served as a model and inspired the team planning the Galileo space craft to gather data on the ice sheet of the Jupiterian moon Europa. The book provides interpretation of, and calculations for, stimulating factors for possible melting and a huge lake's existence at the bottom of the Martian ice sheets.

Download or read book Encyclopedia of Lakes and Reservoirs written by Lars Bengtsson and published by Springer. This book was released on 2012-06-25 with total page 954 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lakes and reservoirs hold about 90% of the world's surface fresh water, but overuse, water withdrawal and pollution of these bodies puts some one billion people at risk. The Encyclopedia of Lakes and Reservoirs reviews the physical, chemical and ecological characteristics of lakes and reservoirs, and describes their uses and environmental state trends in different parts of the world. Superbly illustrated throughout, it includes some 200 entries in a range of topics, including acidification, artificialisation, canals, climate change effects, dams, dew ponds, drainage, eutrofication, evaporation, fisheries, hydro-electric power, nutrients, organic pollution, paleolimnology, reservoir capacities and depths, sedimentation, water resources and more.

Download or read book Applied Climatology written by Allen Perry and published by Routledge. This book was released on 2013-03-07 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Big freeze' conditions, storms, severe flooding, droughts, and heatwaves - recent extremes in weather, with their resultant physical, economic and human losses, highlight the vulnerability of society to changes in the atmosphere. Atmospheric pollution, urbanization, natural atmospheric disasters are causing dramatic changes in climatic environments. Applied Climatology examines the effects of climate on physical, biological and cultural environments. Specialist contributors from Europe, North America and Australasia examine the impacts of changing climates on the functioning and development of physical biological environments including glaciers, water resources, landforms, soils, vegetation and animals. Weather and climate effects day-to-day activities and lifestyles from the clothes we wear to the buildings we design, and the food and energy we produce. This book focusses on the relationship between climate and a wide range of human activities and responses relating to health and comfort, building design, transport systems, agriculture and fisheries, tourism and social, industrial and legal issues. Climate-environment relationships and impacts on human activities are predicted to change dramatically if global warming accelerates at the rates currently proposed. Applied Climatology examines the characteristics and consequences of the changing global climate and considers the future for both natural and human environments.

Download or read book Freezing of Lakes and the Evolution of their Ice Cover written by Matti Leppäranta and published by Springer Science & Business Media. This book was released on 2014-11-28 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: A large number of boreal lakes are ice-covered in winter. However, research and literature of these lakes concerns by far only the open water season. In particular, no textbook on physics of ice-covered lakes exists, and now it would be a proper time to prepare such. Winter limnology has become an increasing active field of research recently. A series of winter limnology symposia was started in 2008 in Finland with nearly 100 participants. The second symposium was held in Berlin in 2010 and the third one is coming in 2012 in Norway. Winter limnologists need strongly a textbook on lake ice physics since the ice acts as their boundary condition.
