This report presents the results of the Corps of Engineers' Section 22 study of ice jam flooding in the Lower Platte River basin. The purpose of the study was to gather and analyze historical data relating to ice jams, with the intent of developing guidance that can be used to alleviate ice jam flooding at seven sites within the study area. Ice event and related information is summarized for each site. Ice event characteristics for the study area are identified and analyzed. A model for predicting the occurrence of ice jams or other ice events within the study area was developed based on data for the Platte River at North Bend, Nebraska. The model provides the minimum discharge associated with ice events for a given date, assuming a threshold value of accumulated freezing degree-days has been reached. A data collection program for future field observations was developed and placed in operation during the winter of 1993-94. General information on ice jam mitigation measures, as well as specific information on such operations as dusting and blasting, is provided. Specific recommendations include increased monitoring of ice conditions, installation of ice motion detectors and water stage recorders, and further study of nonstructural and structural mitigation measures. The use of dusting and blasting as mitigation measures is also presented. The study was divided into six phases. Phase 1 involved collection of historical information from all available data sources, published and oral. Site visits were made to each identified site. Phase 2 entailed analysis and assessment of the collected hydrological, hydraulical, meteorological and ice data.

This is a unique, timely and engaging text with wide ranging geographical coverage. The text brings together, for the first time, information about a vast array of hazards associated with ice and snow, spanning both well known phenomenon (e.g. avalanches) and the less familiar (e.g. river ice jams and ice storms) using, in many cases, material which is rarely seen outside advanced academic research books and journals. The range of ice-related hazards will be introduced and the significance of the current global warming context discussed. Broad physical models of glacial, periglacial and atmospheric cold environments are presented to provide a scientific context for discussion of the human issues of risk, vulnerability impact and mitigation. Key Features: Wide ranging geographical coverage (the Americas, Asia, Australasia, Antarctic & Europe) Localised hazards (avalanches, life storms, landslides) contrasted to those with wider reaching effects (arctic ice loss, ice sheet retreat and wide spread permafrost decay) Includes the latest developments in the field Each chapter includes hazards overview, summery, conclusions, potential projects exercise and key references Includes a supplementary website with figures from the text and further references Each chapter includes a hazards overview, summary, conclusions, potential projects exercise and key references

With major implications for applied physics, engineering, and the natural and social sciences, the rapidly growing area of environmental fluid dynamics focuses on the interactions of human activities, environment, and fluid motion. A landmark for the field, this two-volume handbook presents the basic principles, fundamental flow processes, modeling techniques, and measurement methods used in the field, along with critical discussions of environmental sustainability related to engineering aspects. The first volume provides a comprehensive overview of the fundamentals, and the second volume explores the interactions between engineered structures and natural flows.
