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 River Ice Processes and Ice Flood Forecasting written by Karl-Erich Lindenschmidt and published by Springer Nature. 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 Options for Management of Dynamic Ice Breakup on the Connecticut River Near Windsor Vermont written by Cold Regions Research and Engineering Laboratory (U.S.) and published by . This book was released on 1988 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cornish-Windsor bridge is the longest covered bridge in the United States and has significant historical value. At a large peak flow, dynamic ice breakup of the Connecticut River can threaten the bridge and cause flood damage in the town of Windsor, Vermont. Throughout the 1985-86 winter we regularly monitored ice conditions, including a midwinter dynamic ice breakup on 27 January. We conducted controlled release tests over the operating range of the turbines at Wilder Dam upstream during both open water and ice cover conditions. These data and observations were analyzed in light of more than 60 years of temperature and discharge records. Our analysis indicates that river regulation presents alternatives for ice management that would minimize the probability of bridge damage and flooding during breakup. The flow can be regulated early in the winter to promote the growth of a stable ice cover, minimizing the total ice production in the reach. In the weeks prior to breakup, sustained releases and above-freezing air temperatures cause melting, weakening and gradual breakup of the ice, greatly reducing the flooding potential. Also, it is possible to produce a controlled ice breakup prior to an imminent natural event at lower stage and discharge. All of these ice control alternatives have associated power production costs.

Download or read book Ice Control in River Harbors and Fleeting Areas written by Roscoe E. Perham and published by . This book was released on 1988 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ice control in river harbors and fleeting areas in the northern tier of the United States east of the Mississippi River is handled mainly by the barge and towboat companies. Fleeting area protection in many locations is provided by ice piers and mooring cells. When possible, unused barges are anchored in side channels and below islands or set along one side of the waterway in large groups for ice protection. Ice-breaking is done by towboats, without barges, and a wide track is broken out. Alternative methods of ice control are discussed. (FR).
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.

Available in PDF, EPUB and Kindle. Book excerpt: As part of the River Ice Management (RIM) program, several ice-affected, navigable rivers were studied to find locations where ice problems occur on a regular basis. The rivers studied were the Illinois River and the Ohio River and its tributaries, especially the Allegheny and the Monongahela. Several problem areas were found at river bends, islands, and locks and dams and were generally caused by having too much broken ice in the ship track. One site had a serious frazil ice problem. Ice control structures such as ice booms and deflector booms were investigated for use at certain locations. The report includes a list of 64 ice problem sites, 5 locks and dams that could benefit from ice control structures, and 3 proven structures that are technically applicable. Keywords: Booms equipment, Locks waterways, Allegheny River, Monongahela River, River navigation, Winter navigation. (edc).
