Download or read book River Ice Breakup written by S. Beltaos and published by . This book was released on 2008 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The breakup of a river ice cover can be both fascinating and perilous, owing to ever-changing ice conditions and dynamic processes that sometimes lead to extreme flood events caused by ice jams. Though much progress has been made recently in the study of ice jams, less has been achieved on the more general, and more complex, problem of how to predict the entire breakup process, from the first ice movement to the last ice effect on river stage. This type of knowledge is essential to determining when and where ice jam threats may develop and when they may release and generate steep flood waves that can trigger ice runs and jamming further downstream. In turn, such understanding is invaluable to natural hazard reduction, ecosystem conservation and protection, and adaptation to climatic impacts. This book combines the existing information, previously scattered in various journals, conference proceedings, and technical reports. It contains contributions by several authors to achieve a comprehensive and balanced coverage, including qualitative and quantitative descriptions of relevant physical processes, forecasting methods and flood-frequency assessments, as well as ecological impacts and climatic considerations. The book should be of interest to readers of different backgrounds, both beginners and specialists. -- Publisher's website.

Download or read book The Atlantic Salmon written by Eric Verspoor and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atlantic Salmon is a cultural icon throughout its North Atlantic range; it is the focus of probably the World’s highest profile recreational fishery and is the basis for one of the World’s largest aquaculture industries. Despite this, many wild stocks of salmon are in decline and underpinning this is a dearth of information on the nature and extent of population structuring and adaptive population differentiation, and its implications for species conservation. This important new book will go a long way to rectify this situation by providing a thorough review of the genetics of Atlantic salmon. Sponsored by the European Union and the Atlantic Salmon Trust, this book comprises the work of an international team of scientists, carefully integrated and edited to provide a landmark book of vital interest to all those working with Atlantic salmon.

Download or read book Flood Early Warning Systems written by Daniela Molinari and published by WIT Press. This book was released on 2013 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presenting the results of an ambitious research activity this book intends to understand why Early Warning Systems (EWSs) fail. However, from the beginning, the objective turned out to be challenging; first, because, so far, there is not a shared understanding of what an EWS is (among both researchers and practitioners communities); second, as a consequence, because it is equally unclear when an EWS can be considered successful or not. Due to this, the research needed first to face some “open questions” instead of going straight to the point under investigation. Specifically, it was first necessary to define EWS, identify its components and functions, peculiarities, and weak points. Only at that point, a first attempt to evaluate EWS performance was possible. Flood Early Warning Systems Performance is organised according to the conceptual steps required by the research. In part I the “open questions” about the definition and the role of EWSs are handled, the aim being the identification of how to evaluate their effectiveness/performance. Part II focuses on the real aim of the research, providing concepts and tools to assess EWS performance; suggested tools are also implemented in a case study to describe how they can be applied in practice. Focusing specifically on the topic of flood risk in mountainous regions, the book can be viewed as a sort of manual for EWS designers, managers, and users. It is organised into different independent sections which will appeal both to experts as well as those with an interest in the subject. Most of results can also be exported to other hazards.

Download or read book Ecology of Atlantic Salmon and Brown Trout written by Bror Jonsson and published by Springer Science & Business Media. This book was released on 2011-05-03 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: Destruction of habitat is the major cause for loss of biodiversity including variation in life history and habitat ecology. Each species and population adapts to its environment, adaptations visible in morphology, ecology, behaviour, physiology and genetics. Here, the authors present the population ecology of Atlantic salmon and brown trout and how it is influenced by the environment in terms of growth, migration, spawning and recruitment. Salmonids appeared as freshwater fish some 50 million years ago. Atlantic salmon and brown trout evolved in the Atlantic basin, Atlantic salmon in North America and Europe, brown trout in Europe, Northern Africa and Western Asia. The species live in small streams as well as large rivers, lakes, estuaries, coastal seas and oceans, with brown trout better adapted to small streams and less well adapted to feeding in the ocean than Atlantic salmon. Smolt and adult sizes and longevity are constrained by habitat conditions of populations spawning in small streams. Feeding, wintering and spawning opportunities influence migratory versus resident lifestyles, while the growth rate influences egg size and number, age at maturity, reproductive success and longevity. Further, early experiences influence later performance. For instance, juvenile behaviour influences adult homing, competition for spawning habitat, partner finding and predator avoidance. The abundance of wild Atlantic salmon populations has declined in recent years; climate change and escaped farmed salmon are major threats. The climate influences through changes in temperature and flow, while escaped farmed salmon do so through ecological competition, interbreeding and the spreading of contagious diseases. The authors pinpoint essential problems and offer suggestions as to how they can be reduced. In this context, population enhancement, habitat restoration and management are also discussed. The text closes with a presentation of what the authors view as major scientific challenges in ecological research on these species.

Download or read book Great Peace of Montreal of 1701 written by Gilles Havard and published by McGill-Queen's Press - MQUP. This book was released on 2001-05-25 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last decades of the seventeenth century were marked by persistent, bloody conflicts between the French and their Native allies on the one side and the Iroquois confederacy on the other. In the summer of 1701, 1,300 representatives of forty First Nations from the Maritimes to the Great Lakes and from James Bay to southern Illinois met with the French at Montreal. Elaborate, month-long ceremonies culminated in the signing of The Great Peace of Montreal, which effectively put an end to the Iroquois wars. In The Great Peace of Montreal of 1701 Gilles Havard brings to life the European and Native players who brought about this major feat of international diplomacy. He highlights the differing interests and strategies of the numerous First Nations involved while giving a dramatic account of the colourful conference. The treaty, Havard argues, was the culmination of the French colonial strategy of Native alliances and adaptation to Native political customs. It illustrates the extent of cultural interchange between the French and their Native allies and the crucial role the latter played in French conflicts with the Iroquois and the British. As we approach the 300th anniversary of the treaty's signing in August 1701, Gilles Havard emphasizes its contemporary significance: in signing a treaty with forty separate parties the French recognized the independent sovereignty of every First Nation. This translation is significantly revised and updated from the original French publication of 1992.
