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 275 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.

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.

Download or read book The Periglacial Environment written by Hugh M. French and published by John Wiley & Sons. This book was released on 2017-10-27 with total page 755 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Periglacial Environment, Fourth Edition, is an authoritative overview of the world’s cold, non-glacial environments. First published in 1976 and subsequently revised in 1996 and 2007, the text has been the international standard for nearly 40 years. The Fourth Edition continues to be a personal interpretation of the frost-induced conditions, geomorphic processes and landforms that characterize periglacial environments. Part One discusses the periglacial concept and describes the typical climates and ecosystems that are involved. Part Two describes the geocryology (permafrost science) associated with frozen ground. Part Three outlines the weathering and geomorphic processes associated with cold-climate conditions. Part Four provides insight into the periglacial environments of the Quaternary, especially the Late Pleistocene. Part Five describes some of the problems associated with human occupancy in regions that experience frozen ground and cold-climate conditions. Extensively revised and updated Written by an expert with over 50 years of field research Draws upon the author’s personal experience from Northern Canada, Alaska, Siberia, Tibet, Antarctica, Svalbard, Scandinavia, southern South America, Western Europe and eastern North America This book is an invaluable reference for advanced undergraduates in geography, geology, earth sciences and environmental sciences programs, and to resource managers and geotechnical engineers interested in cold regions.

Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 163. The North, with its vast and varied landscapes, sparse population, and cold climate has always challenged its explorers: physically, mentally, logistically, and technically. The scientific community in particular has known such challenges in the past and does so today, especially in light of the projected intensification of climate change at high latitudes. Indeed, there are clear signs that change is already ongoing in many environmental variables: Air temperature and annual precipitation (including snowfall) are increasing in many regions; spring snow cover extent is decreasing; lake and river ice freeze-up dates are occurring later and breakup dates earlier; glaciers are retreating rapidly; permafrost temperatures are increasing and, in many cases, the permafrost is thawing; and sea-ice extent is at record minimums and thinning.

Book excerpt: Where there’s a Gill, there’s a way. Gordon Gill is a gentle, hard-working Métis man whose journey began on his Iroquois-Cree grandfather’s trapline and evolved into a successful business career. His story is one of change and the passing of not just one, but several eras in the development of Canada’s North and the evolution of the Indigenous struggle. A Métis Man's Dream: From Traplines to Tugboats in Canada's North details the history he met, and made, along the way. Vision, chance, and generosity played integral roles in Gill’s evolution from cook’s helper on the tugboat MV Malta to founding two groundbreaking companies, Northern Arc Shipbuilders and Northern Crane Services. Gill emerged and flourished despite challenging personal injuries, poverty, reading difficulties, and residential schooling. He weathered the ups and downs of northern conditions, the crush of Canada’s National Energy Policy, and changes in culture, economics, and opportunity with a resiliency and way of looking at things that is both visionary and resolutely Métis. Gill is a man of many eras, having experienced many historic firsts and lasts, including experiencing the final days of the Indian Day School of Hay River, and directing the design and fabrication of the first short-throw tugboat in the NWT, the MT Gordon Gill. Neil Gower brings together all of this and more in his thoughtful, sensitive compilation of Gill’s remembrances of the changes he has seen in his lifetime.
