This book was released on 1996 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Describes the effects of flow regulation on the freeze-up processes of part of the Peace River downstream of the Bennett Dam, which has regulated the river flow since 1972. Ice modelling and a review of ice observations and other field data were used to characterise the extent of flow regulation and its effects on ice in the river channel. Explicit equations and algorithms are presented that quantify the processes by which an ice cover forms on large regulated and non-regulated rivers. Work previously undertaken on the Peace River is also described to provide a framework for the calibration of these algorithms for the river in both its regulated and non-regulated condition. A procedure was developed for forecasting freeze-up on a non-regulated river and a stability relationship was derived that uses both air temperature and discharge to determine whether a juxtaposed or consolidated ice cover will form. In addition, the hydraulic characteristics of the Peace River were evaluated for six reaches using the existing data base.

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.

This book was released on 2019-09-25 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book exposes practitioners and students to the theory and application of river and lake ice processes to gain a better understanding of these processes for modelling and forecasting. It focuses on the following processes of the surface water ice: freeze-up, ice cover thickening, ice cover breakup and ice jamming. The reader will receive a fundamental understanding of the physical processes of each component and how they are applied in monitoring and modelling ice covers during the winter season and forecasting ice floods. Exercises accompany each component to reinforce the theoretical principles learned. These exercises will also expose the reader to different tools to process data, such a space-borne remote sensing imagery for ice cover classification. A thread supporting numerical modelling of river ice and lake ice processes runs through the book.

Download or read book Flow Control to Manage River Ice written by Andrew M. Tuthill and published by . This book was released on 1999 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes flow-control methods for reducing ice problems in rivers. Objectives include reducing ice interference with winter hydroelectric production and navigation, ice jam flood mitigation, as well as ensuring minimum winter flows for fish and water supply. The winter season is divided into three periods. During early winter, the main objective of flow control is to promote the rapid formation of a smooth, stable ice cover. For the midwinter period, the aim of the river regulation is to maintain an intact ice cover and avoid premature ice breakup. During the final winter period, the goal is to minimize adverse effects of ice breakup. Examples illustrate the methods and objectives, emphasizing innovative approaches. Available flow regulation planning tools are described and valuable research directions identified.

Download or read book The Regulation of Peace River written by Michael Church and published by John Wiley & Sons. This book was released on 2014-12-31 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive overview of the first longitudinal study of the downstream response of a major river to the establishment of a large hydropower facility and dams. Peace River, a northward flowing boreal river in northwestern Canada was dammed in 1967 and the book describes the morphological response of the 1200 km downstream channel and the response of riparian vegetation to the change in flow regime over the first forty years of regulated flows. Beginning with a description of the effect of regulation on the flow and sediment regimes of the river, the book proceeds to study changes in downstream channel geometry on the main stem, on the lowermost course of tributaries, and on the hydraulic geometry, the overall morphology of the channel, and riparian vegetation succession. The river is subject to annual freeze-up and break-up, so a chapter is devoted to the ice regime of the river. A chapter compares the effects of two extraordinary post-regulation flood events. The penultimate chapter presents a prediction of the ultimate equilibrium form of the regulated river based on rational regime theory. An online database of all the main observations will provide invaluable material for advanced students of river hydraulics and geomorphology. This book carefully brings together a range of studies that have been previously inaccessible providing a rare and comprehensive analysis of the effects of a big dam on a river, a river that itself represents an example of the kind of system that is likely to receive considerable attention in the future from dam engineers and environmentalists. • An invaluable reference to river scientists, hydroelectric power developers, engineers and environmentalists • Focus on a northward flowing boreal river, a type that holds most of the remaining hydroelectric power potential in the Northern Hemisphere • Exceptional separation of water and sediment sources, permitting study of the isolated effect of manipulating one of the two major governing conditions of river processes and form • Unique example of water regulation and both natural and engineered flood flows • Detailed study of both morphological changes of the channel and of the riparian vegetation • Online data supplement including major data tables and numerous maps.

This book was released on 2017-08-14 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the current environmental changes due to global warming in northern Eurasia, especially focusing on eastern Siberia. Spring flooding, ice-jam movements, and monitoring using remote sensing are included. Additionally, current reindeer herding of indigenous peoples in Siberia and related environmental changes such as waterlogging, rising temperatures, and vegetation changes are addressed. As a summary, the book also introduces readers to adaptation strategies at several governmental levels. The book primarily focuses on 1) introducing readers to global warming and human-nature dynamics in Siberia, with special emphasis on humidification of the region in the mid-2000s, and 2) describing social adaptation to the changing terrestrial ecosystem, with an emphasis on water environments. Adaptation strategies based on vulnerability assessments of environmental changes in northern Eurasia are crucial topics for intergovernmental organizations, such as the IPCC (Intergovernmental Panel on Climate Change). Thus, the book offers a valuable resource not only for environmental researchers but also for several stakeholders regarding global environmental change.

Download or read book Numerical Modelling of Ice Floods in the Ning-Meng Reach of the Yellow River Basin written by Chunqing Wang and published by CRC Press. This book was released on 2018-01-29 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ning-Meng reach of the Yellow River basin is located in the Inner Mongolia region at the Northern part of the Yellow River. Due to the special geographical conditions, the river flow direction is towards the North causing the Ning-Meng reach to freeze up every year in wintertime. Both during the freeze-up and break-up period, unfavourable conditions occur which may cause ice jamming and ice dam formation leading to dike breaching and overtopping of the embankment. Throughout history this has often led to considerable casualties and property loss. Enhanced economic development and human activities in the region have altered the characteristics of the ice regime in recent decades, leading to several ice disasters during freezing or breaking-up periods. The integrated water resources management plan developed by the Yellow River Conservancy Commission (YRCC) outlines the requirements for water regulation in the upper Yellow River during ice flood periods. YRCC is developing measures that not only safeguard against ice floods, but also assure the availability of adequate water resources. These provide the overall requirements for developing an ice regime forecasting system including lead-time prediction and required accuracy. In order to develop such a system, numerical modelling of ice floods is an essential component of current research at the YRCC, together with field observations and laboratory experiments. In order to properly model river ice processes it is necessary to adjust the hydrodynamic equations to account for thermodynamic effects. In this research, hydrological and meteorological data from 1950 to 2010 were used to analyse the characteristics of ice regimes in the past. Also, additional field observations were carried out for ice flood model calibration and validation. By combining meteorological forecasting models with statistical models, a medium to short range air temperature forecasting model for the Ning-Meng reach was established. These results were used to improve ice formation modelling and prolong lead-time prediction. The numerical ice flood model developed in this thesis for the Ning-Meng reach allows better forecasting of the ice regime and improved decision support for upstream reservoir regulation and taking appropriate measures for disaster risk reduction.
